PREDIMAX® Injection Hose Injection Hose for Economic Sealing of Construction Joints in Concrete Structures _________________________________________________________________________________________________________________________________

PREDIMAX 11 and PREDIMAX 19Product PREDIMAX is a double-jacketed PVC based hose with offset openings and/or slots for outlet of compressed injection material to seal joints in subterranean con-structions. The openings in the interior hose are offset from the openings in the outer hose, that is to say, ce-ment paste is prevented from entering.

For installation, you have to fix the injection hose to the first concrete section by means of some suitable fas-tening and imbed it with the next concrete-work phase.

Use (in general) The injection hose is used for sealing of construction joints which are permanently or occasionally exposed to loads due to subterranean, down-the-slope or sur-face water. Construction joints which are required for structural engineering reasons can be designed non-positive and watertight.

Features for Installation Sufficient cross section of the duct (reducing inner

friction of injection material thus allowing economical compression lengths) and permeability of the com-pression duct and outlet openings after concreting.

Cement paste is prevented from entering during concrete work because of the hose-in-hose system

Robust during installation under building-site condi-tions, fastening system included

Easy handling and time-saving fitting No unwanted twisting when installing from the reel,

because hose is circular Outlet of injection material from the concreted hose

system even under slight pressure, that is to say, outlet of material is assured to all sides

Smooth surface to avoid unwanted bonding between injection hose and concrete. PREDIMAX may there-fore be applied quite easily with any injection materi-al.

Favourable relation between price and performance, maximum reliability, for multiple injections.

Suitable for injection of regular cement (PREDIMAX 19 only), fine cement, ultra fine cement, PU resin or PU foam resin, EP resin or acrylates

Can be used for multiple injections Product certification to DIN EN ISO 9001 Injection hose with continuous markings of meter

length and control number PREDIMAX injection hose is a unique, patented

technology made in Switzerland

Application Horizontal sealing of constructional joints:

base/base, base/wall, wall/cover, cover/cover Vertical sealing of constructional joints: wall/wall Overground and underground workings, civil engi-

neering, tunnel constructions, special-purpose PREDIMAX may be used for compressing and/or

injecting resins, foamed resins, acrylates and ultra-fine-cement suspensions, fine cements or cement lime. PREDIMAX 19 can be injected beside the above mentioned injection media also with regular Portland Cement.

CEM 11 Injection Tube Injection Tube for Economic Sealing of Cold Joints in Concrete Structures _________________________________________________________________________________________________________________________________

An efficient, well-priced injection tube system for structural waterproofing Product PVC based injection hose for economical sealing of any construction joints in subterranean construction.

Single-wall hose of PVC based material, with slightly cone-shaped openings and slots from inside to outside for the compressed injection material to be squeezed out in order to seal the joints in underground construc-tions. The openings get closed by their geometry thus avoiding efficiently any penetration of cement paste into the injection hose.

The smooth surface of CEM 11 eliminates any unwant-ed bond between injection hose and concrete. The CEM 11 injection tube system can be used for any injection resin. Injections are possible even after years, because the smooth surface CEM 11 does not allow any sinter deposits or obstructions in the system. Use The CEM 11 injection hose is used for sealing of con-struction joints which are permanently or occasionally exposed to groundwater or surface water. CEM 11 is an efficient, effective injection tube system used to prepare waterproof, gastight and frictional con-struction joints. Application

Suitable for all kind of vertical and horizontal construc-tion joint / cold joint sealing! Product Characteristics Sufficiently dimensioned inside diameter and permea-

bility of the injection hose and the outlet openings af-ter concrete work. Prevents cement paste from penetrating during con-

crete work. Sturdy when being incorporated under building-site

conditions with fastening system included. Easy handling, simple time-saving fitting No unwanted twisting when you incorporate from the

coil as there is a circular hose.

Material to be injected leaves the hose system em-bedded in concrete, even under reasonable pressure, that is to say material is reliably coming out to all sides (opening injection-pressure min. 0.5 bar). Can be used for multiple injections by using acryIate-

gel or PU-gel. Outlet opening shaping conically from inside towards

outside. Some trifle opening resistance only has to be overcome therefore. Smooth surface, hence no unwanted bond between

injection hose and concrete. Very favourable balance of price and performance. Technical Data

Installation of the BPA Injection Hose System _________________________________________________________________________________________________________________________________

The PREDIMAX/CEM 11 injection hose is easy to install when you consider the following items of this installation manual: Put the hose in the middle of the cold joint. The connec-tion, ventilating hose / PREDIMAX/CEM 11 has to be placed completely inside the concrete structure.

The hose has to be well set on the cold joint and has to be fastened with hose clamps at approx. 15 cm dis-tance (depending on surface of the concrete of the construction joint). Overlapping: The overlapping should at least be 10 cm.

The injection ends shall be placed towards outside the formwork in order to be easily found again. Two differ-ent possibilities are shown:

Installation of the injection hose system by using shut-ter connector including rubber plate and a spider (for easy installation on the reinforcement) Installing the ventilation hoses inside an end box: Important: Ventilation hoses have to be fixed in order to avoid a replacement during the concrete work.

QUELLMAX® Plus Bentonite Waterstop Tape with Patented Rain Protection __________________________________________________________________________________________________________________________________

With General Building Code Test Certificate (abP)

Product QUELLMAX Plus is a technically matured and moreo-ver very price worthy swellable bentonite joint-sealing tape with crystallisation additives. QUELLMAX is used as a waterstop in concrete construction joints. QUELLMAX is tested up to 7 bar water pressure. QUELLMAX Plus The swellable bentonite waterstop tape consists of bentonite embedded in a matrix of highly molecular polyisobutylene caoutchouc and special fillers and crystalline admixtures (patented composition).

Contact with rain or general site water will not activate the product, but when QUELLMAX Plus is covered by concrete, the alkaline environment breaks down the coating and the QUELLMAX Plus will then be activated by leak water. Features QUELLMAX Plus is the only swellable bentonite joint-sealing tape that can be used without any compromise, because QUELLMAX Plus can be installed independently of

any weather condition, that means no unwanted swelling during installation (rain-protection)

Patented coating delays swelling from contact with water of 72 hours.

Application QUELLMAX Plus should be placed in in-situ concrete constructions because the swellable bentonite water-stop tape will be completely covered on all sides by concrete (min. 8 cm concrete cover are required) to make sure that the swelling sealing pressure can be built up. Advantages QUELLMAX Plus seals in two phases: -First phase: sealing by immediate swelling -Second phase: sealing by crystallisation Great swelling capacity (> 300 %) Easy Handling

No time-consuming setting on edges Self injecting effect, that is to say penetration into any

cracks and cavities because of a powerful swelling. Second sealing process by concrete crystallisation

Swelling and shrinkage are infinitely reversible Dimensionally extremely stable, not sticky, even at

high temperatures in summer High mineral portion, hence no fatigue of materials:

Sodium-bentonite reacts even decades after having been incorporated

No negative influence on the successful building-site routine

QUELLMAX® Blackstop Standard Bentonite Waterstop Tape __________________________________________________________________________________________________________________________________

With General Building Code Test Certificate (abP)

Product QUELLMAX Blackstop is a technically matured and moreover very well-priced swellable bentonite joint-sealing tape with crystallisation additives (patented). QUELLMAX is used as a waterstop in concrete con-struction joints. QUELLMAX is tested and approved up to 7 bar water pressure. QUELLMAX is also tested for use in changing water tables. QUELLMAX The swellable bentonite waterstop tape consists of bentonite embedded in a matrix of highly molecular polyisobutylene caoutchouc and special fillers and crystalline admixtures (patented composition). Supplied as a robust strip, QUELLMAX is simply fas-tened onto an existing joint face before the next con-crete pour. Any subsequent water leakage through the joint activates the QUELLMAX, which takes up leaking water and swells. This swelling action expands the product into the water flow paths (active self-injecting process) and effectively seals against water leakage through the cold joint. Features Compared with any other traditional joint sealants (PVC joint-sealing tape, joint-sealing sheets, etc.), QUELLMAX Blackstop is quite economical and reliable, because sources of errors are reduced to minimum the best ratio of price and performance is assured Application QUELLMAX shall be placed only in in-situ concrete constructions because the swellable bentonite water-stop tape shall be completely covered on all sides by concrete (min. 8 cm concrete cover are required) to make sure that the swelling sealing pressure can be built up. Advantages QUELLMAX seals in two phases: -First phase: sealing by immediate swelling -Second phase: sealing by crystallisation Great swelling capacity (> 300 %)

CEMswell – Hydrophilic Swelling Rubber _________________________________________________________________________________________________________________________________

CEMswell – Hydrophilic Rubber Shield-driven tunnels (TBM) are currently being used for construction work at even greater depths and higher water-pressure environments. The resultant need for improved water sealing characteristics is best met by water-expanding sealant materials, which swell on contact with water. Introduction Shield-driven tunnels are common features of such construction works as subways, water supply and sew-er systems in cities, tunnels, cable lying, etc. Recent trends in shield-driven tunnels have been towards new applications, increase and decrease in section size, and also construction at greater depths or under the seabed where measures against high-pressure water are of vital importance. CEMswell is a hydrophilic high quality product for sealing all joints in prefabricated concrete constructions. New Type of Rubber Seal

CEMswell is a new expanding rubber sealing material that is intended mainly for sealing of joints in tunnels and shafts. It has been developed for the successfully use in tunnels in pressure conditions up to 5 bar water pressure. Expansion up to 400 % CEMswell is an extruded rubber-based compound made from butyl rubber, hydrophilic resin, polyethylene, silicon and special admixtures. On contact with water it is capable of swelling up to 4 times its own volume, and under conditions of confinement will mould itself to exert pressure evenly on the surrounding surfaces, even when these are rough and the gaps to be filled are of uneven size. This feature assures a good water-proof seal without the need for any sort of high-compression force.

Shape and Size CEMswell is available in numerous standard shapes and sizes, and can also be extruded in non-standard shapes to meet client’s special requirements or in com-bination with ordinary non-expanding rubber. Three main grades are produced and in stock:

18x7mm: 6 rolls à 12 m (72m / box) 23x15mm: 5 rolls à 6 m (30m / box) 23 mm: 4 rolls à 5 m (20m / box) Technical Data

Colour: Grey (standard) Shore A: 38 Elongation at break 490 / 770 % Tensile strength 1.1 / 2.1 MPa Specific weight: 1.25 g/cm³ = 1.25 Volume of swelling: approx. 400 % Working tempera-ture:

-30 °C to +70 °C

Shelf life: 3 years when stored protect-ed constantly against frost and weather conditions. Concrete cover shall be at least 8 to 10 cm

Do not use CEMswell to seal cold joints of in-situ concrete constructions! CEMswell shall be used to seal joints of prefabri-cated concrete constructions!

CEMproof® CEMswell “Inject” CEMswell “Inject” combines CEMswell Swelling Rubber and CEM 11/PREDIMAX 11 Injection Hose _________________________________________________________________________________________________________________________________

Product for economical sealing of construction joints in watertight concrete structures Product Sealing with swelling rubber and injection hose consists of the products CEMswell swelling rubber and CEM 11/PREDIMAX 11 injection hose. Both together they result in the unique double sealing of construction joints (swelling and injecting). The injection tube ensures the injection material to be squeezed out at any time. CEMswell “Inject” The profile is used for sealing construction joints which are permanently or occasionally exposed to groundwa-ter, slope water and/or surface water. The structurally necessary construction joints can be sealed tight to water pressure. Product Characteristics CEMswell “inject” can be applied quite easily with any injection material. Can be used for simple injection with CEM 11 by

using PU-resins, EP-resins, etc. Can be used for multiple- and cement injections with

PREDIMAX 11 by using acrylate-gel or PU-gel. Injection hose with ongoing control-numbers Rain protected for 10 hours permanent rain Swelling capacity of minimum 400 % Dual safety! Swelling and Injecting! Advantages Swelling and injecting Sturdy when being incorporated under building-site

conditions with fastening system included Easy handling; simple time-saving fitting. Injection only if necessary!

Material to be injected leaves the hose system em-bedded in concrete, even under reasonable pressure, that is to say material is reliably coming out to all sides (opening injection-pressure min. 0.5 bar).

The smooth surface avoids unwanted bonding be-tween injection hose and concrete, therefore the CEMswell “inject” is easy to inject. Even after years an injection is still possible as the smooth surface does not allow any sinter deposits or obstructions in the system.

Very favorable balance of price and performance. Installation Installation can either be with: CEMstar adhesive or CEM 805 adhesive Nails or clamps A minimum of 8 cm concrete cover is required. Technical Data Injection Material PU-resin (Crack Seal), PU foam resin (SealStop F + additive), EP-resin, acrylate (without corrosive behav-iour).

CEMflex VB - Steel Plate Waterstop __________________________________________________________________________________________________________________________________

With General Building Code Test Certificate (abP) CEMflex VB - Steel Plate Waterstop The CEMflex VB elements are provided with a special coating on both sides. The connection of the special coating to the concrete prevents any water-flow through the concrete construc-tion joint. Besides the extremely good connection of the special coated steel plate to the surrounding concrete there are some other chemical reactions such as light swelling, crystallization, self-healing of concrete cracks and a natural sintering / crystallization (natural formation of limestone) of concrete cracks. Only 3 cm of concrete cover on both sides are neces-sary to seal the cold joint up to 5 bar (50 m water-pressure) The elements are 2,000 mm long, 150 mm high and about 1.25 mm thick. The special coating is not sticky and therefore no protection foil is necessary, which has to be removed before concrete work starts. Areas of Application CEMflex VB CEMflex VB can be used in all construction joints, horizontally or vertically, up to a maximum water-pressure of 80 meter (8 bar). Areas of application: Horizontal + vertical sealing of any concrete con-

struction joints! Waterproof cold joints in foundation-, basement-,

civil engineering work as well as in tunnel construc-tions, underground constructions and special-purpose solutions.

CEMflex VB Product Characteristics Galvanized steel metal plate (b = 0.75 mm / l = 2,000 mm / h = 150 mm) provided on both sides with a 0,5 mm thick special coating which sticks to the concrete chemically and seals permanently the joint which has to be sealed.

CEMflex VB is an active steel plate waterstop! The sealing function is based on the active crystalliza-tion process as well as the supported natural sintering process of concrete. Characteristics CEMflex VB The extreme good connection behaviour to the con-crete is responsible for the very good waterproofing property. CEMflex VB supports the natural sintering / crystalliza-tion of the cold joint as well as the cracks. Installation of CEMflex VB CEMflex VB with coating on both sides has to be in-stalled directly on top of the reinforcement. CEMflex VB has to be fixed by using the special omega steel plate holder. The overlapping has to be at least 5 cm. Form of Delivery / Storage The single element is 2,000 mm long, 150 mm high and 1.25 mm thick. In wooden boxes of 50 pieces = 100 m. CEMflex VB can be stored in dry and cold conditions. Installation example

-CEMflex VB steel plate- CEMflex VB

CEMflex VB steel plate reacts because of its various encapsulated components in the patented coating in combination (direct contact to concrete) with the components of the surrounded concrete.

Besides the extremely good connection of the special coated steel plate to the surrounding concrete there are some chemical reactions starting such as light swelling, crystallization, self-healing of concrete cracks and a natural sintering / crystallization (natural formation of limestone) of concrete joints as well as cracks.

The components of the special coating need water or water-based liquids in order to start automatically the chemical reaction; this natural crystallisation process is an active self-healing process! ►CEMflex VB is an “active“, water reacting steel plate waterstop!

This active self sealing process starts automatically by water contact. The function of this sealing process is secured even after decades of installation. By the use of CEMflex VB there will always be an automatically (active) waterproofing reaction / process. The crystalli-zation, self-healing of concrete cracks will penetrate deeper and deeper in the concrete structure.

The waterproofing reaction of CEMflex VB steel plate waterstop has been tested on the independent/public Institution of the University and is confirmed with an abP (General Building Code Test Certificate / Approval)

Application Prior to application, CEMproof Add X is added to Seal-Stop F to increase its reactivity. The reaction mix thus obtained maintains its state for at least 8 hours without significant viscosity increase. After mixing with CEMproof Add X, a skin may be formed on the surface of the liquid by reaction with the humidity contained in the air; but this does not affect the pumping operation.

SealStop F / CEMproof Add X products are injected as a single component via packers into the water-bearing zones using manual or motor-driven pumps. When in contact with water, the reaction mix foams up strongly and hardens. If the zone to be sealed contains insuffi-cient water, a full hardening of the SealStop F mass can be achieved by preliminary or subsequent water injection.

In contrast to the two-component systems, SealStop F will not harden in the injection pipe for hours since con-tact with the water contained in the ground is necessary for hardening.

Preferably, SealStop F is used for stopping the water flow from working joint with preinstalled grouting hoses such as PREDIMAX injection hose systems or CEM 11 injection hose system. Immediately after stopping the water flow by pumping SealStop F (single-component foaming PU-resin), CEMproof CrackSeal (two-component PU-resin) has to be injected to achieve a permanent elastic seal.

Immediately after ending the injection work flush the pump with CEMproof CleanEx in order to prevent clog-ging. For standstill periods of more than one day, fill the pump with CEMproof CleanEx afterwards.

For the consolidation of soil SealStop F is used without CEMproof Add X and has to be injected via injection hoses (PREDIMAX/CEM 11) or other injection pipes into natural moist or wet sand. The maximum radius of injection is approx. 30 cm; with a bigger radius the core is left uncured. The injection pressure should be no greater than the overburden pressure in order to avoid fracturing of the ground.

Recommendation: We recommend storing the products prior to processing for at least 12 h at a minimum temperature of 15 °C in order to achieve the recommended processing temper-ature of between 15 °C to 30 °C. When the material is warmed up, local overheating, e.g. at the container wall, must be avoided by any means.

18

Composition and Properties Components SealStop F consists of modified isocyanates with sof-teners and additives. CEMproof Add X is a catalyst blend.

System: SealStop F cures by reaction with ambient water yield-ing a polyurethane / polyurea foam. The expansion rate of the foam depends in the first place on the backpres-sure affected by the propagation of the resin into the structure to be sealed, i.e. wide cracks/gravel result in a high foaming factor, narrow cracks / fine sand in a low expansion rate and high strength.

Final Product: Cured SealStop F does not shrink nor swell with water, which makes this resin very stable. Form of Delivery / Storage Packing: SealStop F CEMproof Add X 20 kg in a can 4.5 kg in a can

System: The resin mix penetrates the cracks to be sealed. The major part of the water in there is displaced by the hy-drophobic resin; the remainder causes the acceleration of the curing and the formation of a mainly closed cell foam resin.

Final product: After more than 10 h, the resin is solid; the final curing takes several days. The cured resin is elastic and ex-tendable even in tabular adhesion. It meets the re-quirements of the minimum extendability of 10 % ac-cording to ZTV-ING. CEMproof CrackSeal T is compatible with groundwater. Application Generally, the resin mix is injected via a borehole packer and a borehole into the fissure to be sealed until resin matter is discharged by boreholes for checking purposes.

and standards for repair & protection of concrete

Technical Data Air- and undergound temperatures: Minimal +4 °C (at least, however, +3 °C over the dew point), maximal +50 °C

Estimated material consumption: Normal consumption is between 100 and 200 g/m² for the first coating and between 50 and 150 g/m² for the second coating. The material consumption depends on the absorbency, surface roughness and moisture of the underground as well as on the application- and ambient temperature. Therefore, the appliance of a test surface is recommended to define the object-specific material consumption.

Viscosity: CEMproof PORFÜLL is a super low viscosity impregna-tion with a slightly increasing viscosity at low tempera-tures.

Attendance time between the coatings: The attendance time between the coatings depends on the absorbency of the underground and is normally between three and six hours. Before applying the se-cond coating, the impregnation of the first coating should have penetrated into the underground.

Curing time: The curing times of the treated surface depend on the ambient temperature and are indicated below. The temperature of the ambient air and underground should not be less than 4 °C.

Overcoating:A PORFÜLL treated surface can be coat-ed with suitable paintings, coatings or floor covering adhesives. The coating material can be applied in the tacky surface. To define the compatibility, samples have to be applied first. The Innovation PORFÜLL Impregnation Coating

By adding the liquid component CEMdicht flex the miner-al sealant silt will become so flexible that it can be ap-plied to highly stressed, crackprone undergrounds (c.f. Technical leaflet "CEMdicht flex"). The liquid component CEMdicht flex+ has crystalline characteristics in addition.

CEMdicht holds the General Building Code Test Certifi-cate (abP). It is constantly controlled as required in the German Bauregelliste. Uses CEMdicht is used to protect buildings and parts thereof against ground dampness, pressing water and non-pressing water. It is applied: - at vertical waterproofing of earth touching constructions - for exterior waterproofing of walls (even afterwards) - for waterproofing of concrete slabs and foundations - for vertical waterproofing of splash water areas at wall bases - for waterproofing at the cross-section of walls and concrete slabs - for waterproofing against interior water pressure (water tanks) - Interior waterproofing against exterior water pressure flow (even afterwards) - waterproofing against temporarily pressing water from the inside during construction work.

CEMdicht is applied on: - reinforced concrete as per DIN 1045, - solidly filled masonry brick work as per DIN 1053 - cement plaster as per DIN 18550.

CEMdicht is suitable as waterproofing coating for under-ground screeds, plasters of the mortar groups PI, PII, and PIII as well as for tiles and slabs. Application of 1 Component – not flexible The underground should be firm, load carrying and free from separating substances. Concrete undergrounds have to be free of gravel nests, cracks, and other une-venness. The concrete neither must not contain additives nor be treated with products that harm the sealant silt. Unevenness and cracks have to be equalized with a PIII cement mortar before waterproofing.

Brickwork with joints has to be plastered with a plas-ter of PIII mortar group (minimum layer thickness 10 mm). Onto solidly filled brickwork as per DIN 1053 CEMdicht can be directly applied.

Do not work at temperatures below +5 °C or when frost or rain is expected. Do not apply onto frozen underground. If necessary wet the underground be-fore application.

Mixing: Mix CEMdicht with clean water until obtaining a lump free paste. Water amount needed: approx. 8.5 l/bag for a brushable consistency. About 7.5 l/bag for a trowelling consistency. To improve the workabil-ity a bonding emulsion can be added (approx. 1 l/bag) to the mixing water. CEMdicht can be applied with suitable sprayguns.

Apply minimum 2 layers of the mineral sealant silt (against ground dampness and with non-pressure water flow) or minimum 3 layers (against pressure water flow or horizontal waterproofing). Each layer must have the same material consistency following the tool with which the material is applied: brush, trowel or suitable spray gun. Waiting time between two layers has to be at least so long that the previous layer will not be damaged when applying the next one. Keep the minimum thickness on all edges and corners. Minimum thickness of the dry layer against ground dampness and with non-pressure water flow is 2 mm, in all other cases 3 mm. Maximum thickness of dry layer is 5 mm.

Amount required: Approx. 4 kg/m² against ground dampness and non-pressure water flow (= about 2 mm layer thickness). Approx. 7 kg/m² against pres-sure water flow (= about 4 mm layer thickness). The amounts given refer to the dry mortar. CEMdicht 3 in 1

Working time will shorten with high outdoor temperatues, just as it will lengthen with low outdoor temperatues. Prepared mineral sealant silt should be used within two hours. Fresh material can be rinsed off with clean water.

Aftertreatment: Fresh waterproofing is to be protected for about three days against too much sun, wind and heat. If necessary, keep moist. Allow ten days minimum for the mineral sealant silt to be load carrying and fully function-al. Damage at the new waterproofing can be repaired with CEMdicht. Protect sealant silt coated surfaces by suitable protection coats. The foundation pit is to be filled in accordance to the standard building regulations. Application of 2 Component – flexible and 2 Component – flexible + crystallizing addi-tives The substrate must be firm, load carrying and free from separating substances. Concrete has to be free of gravel nests, cracks, and other unevenness. The concrete nei-ther must not contain additives nor be treated with prod-ucts that harm the sealant slurry.

Gravel nests have to be equalized with a cement mortar before waterproofing. Edges have to be broken, grooves have to be rounded. Brickwork with joints has to be plas-tered with a cement-plaster (minimum layer thickness 10 mm). Onto solidly filled brickwork CEMdicht “flex” can be directly applied. Do not work at temperatures below +5 °C or when frost or rain is expected. Do not apply onto frozen substrate. Substrate has to be thoroughly wet before application.

Mixing: Mix thoroughly one 30 kg bag CEMdicht with one 10 litre can liquid component CEMdicht „flex“ (slowly running drill with rotating mixer). If necessary add a small amount of water to obtain the working consistency.

Apply minimum 2 void-free layers of the flexible sealant slurry (against ground dampness and with non-pressure water flow) or minimum void-free 3 layers (against pres-sure water flow or horizontal waterproofing). Each layer must have the same material consistency following the tool with which the material is applied: brush, trowel or suitable spray guns. Waiting time between two layers has to be at least so long that the previous layer will not be damaged when applying the next one. Keep the mini-mum and maximum thickness on all edges and corners. Minimum thickness of the dry layer against ground dampness and with non-pressure water flow is 2 mm, in all other cases 2.5 mm. Maximum thickness of dry layer is 5 mm.

2 component flex and 2 component flex+

Amount required: Approx. 3 kg/m² against ground dampness and non-pressure water flow. Approx. 4 kg/m² against pressure water flow. The amounts given refer to the dry mortar.

Prepared flexible sealant slurry should be used within 30 minutes. Fresh material can be rinsed off tools with clean water.

Aftertreatment: Fresh waterproofing is to be protected for about three days against too much sun, wind and heat. If necessary, keep moist. Allow ten days mini-mum for the flexible sealant slurry to be load carrying and fully functional. Damage at new waterproofing can be repaired with CEMdicht “flex“.

The processing time is about 60 minutes at a tempera-ture of +20 °C and a humidity of 60 %. Layers more than 1 mm thick should be avoided as cracks may arise be-cause of the high amount of adhesive agent. CEMdicht Sealing Tape 2000 The sealing tape 2000 is pressed on joints over surfaces that are treated with waterproofing materials and with CEMdicht flex. The surface sealant (at least 2 cm in width and wider than the sealant tape) is to be applied on both sides of the bridged joints. The sealing tape is to be applied on the new surface, evenly placed without creas-ing. Then the sealant can be applied. The area of the settlement joint (for the subsequent elastic joint applica-tion) should be kept free from sealant. The edges of the sealing tape are to be bonded with an overlap of at least 5 cm and with the sealant, covering the complete surface without creasing. Note During the hardening phase water needs to be kept away. Protect newly-laid CEMflex sealing tapes against sunshine, cold draft, rain, and frost. Allow 7 days mini-mum for the sealing tapes to be fully water-proof against water pressure. Negative water can cause the sealing tape to chip off due to frost. The CEMdicht Sealing Tape 2000 seals joints and must be protected against mechan-ical damage. Products containing dissolvents and block-ing vapour cannot be applied onto the sealing tape. A priming coat without any open pores avoids direct con-tact with metals such as copper, zinc and aluminum.

The CEMdicht 3 in 1 powder component contains cement and therefore reacts alkaline due to moisture. So please note: � protect skin and eyes. � irritations: rinse thoroughly with water. � eye contact: rinse thoroughly with water for about 10 minutes and seek medical advice. Safety Precautions Transport: Not a hazardous material Ecology: The powder is hazardous to water and therefore needs to be removed according to legal regulations. Do not drop into sewage system, waters or ground. Disposal: Let both components react and dispose hard cured material according to local guidelines. For detailed information please ask for the health data sheet.

CEMproof® CEMdrain Draining System High Quality Special-draining System __________________________________________________________________________________________________________________________________ Product Conventional drainage system (sand, gravel, drainage pipes and filter fabrics) restrict the creativity of archi-tects and construction engineers in the design and construction of buildings, (re)development of urban areas and infrastructures such as roads and high-speed railways.

Use CEMdrain is the draining system which has full draining capacity, even after decades.

The use of natural materials in conventional systems prevents an accurate calculation of the drainage capac-ity. This sometimes results in overdimensioning, higher costs and excessive use of space. Another risk is un-derdimensioning, causing failure to achieve the re-quired drainage capacity, eventually leading to dam-aged buildings, roads or green areas.

CEMdrain eliminates such problems permanently by offering a system that is both simple and comprehen-sive, providing architects and construction engineers with the ability to achieve the proper drainage capacity and to accurately determine the dimensions of the drainage pipes and sewer systems needed.

CEMdrain can be used for tunnel draining, basement draining, foundation draining and excavation draining.

CEMtobent® DS Double SealSealing System _________________________________________________________________________________________________________________________________ Product CEMtobent lining system replaces all conventional wa-terproofing methods used in civil engineering, such as bituminous materials, coatings and synthetic foils of all kinds. The innovative manufacturing technology differen-tiates CEMtobent Lining System from similar products, which also use PE and bentonite as waterproofing agents. CEMtobent DS is a unique bentonite membrane especially created for structural waterproofing! CEMtobent DS CEMtobent DS is a waterproofing system, which consists of two complementary components: the primary liner: a high-quality (GCL)

geocomposite clay liner the secondary liner: a 3D composite (PE honeycomb

with a unique cell structure where the swelling sodium bentonite powder is encapsulated.

CEMtobent is a highly effective waterproofing composite of high strength geotextile and 5,00 kg of natural activat-ed sodium bentonite powder per square metre. The high swelling, low permeable activated natural sodium benton-ite is encapsulated between a non-woven and a 3-dimensional PE sheet. A patented mechanical connec-tion interlocks the geotextiles together forming an ex-tremely strong composite that maintains the equal cover-age of bentonite, as well as, protects it from inclement weather and construction related damage. CEMtobent has a unique rain-protection layer and has one open and one completely closed side. This feature allows the use of CEMtobent also in areas where fluent groundwater levels are expected.

Once backfilled, CEMtobent hydrates and forms a monolithic waterproofing membrane. CEMtobent can be installed in any weather condition to green con-crete, and most importantly, has proven effective on both new and remedial waterproofing projects world-wide. CEMtobent works by forming a low permeability membrane upon contact with water. When wetted, unconfined bentonite can swell up to 8 - 12 times its dry volume. When confined under pressure the swell is controlled, forming a dense, impervious waterproofing mem-brane. The swelling action of CEMtobent can seal small concrete cracks caused by ground settlement, concrete shrinkage, or seismic action; problems over which there is normally no control. CEMtobent forms a mechanical bond to concrete when the geotextile are encapsulated into the surface of poured-in-place concrete.

CEMtobent DS is tested up to 5 bar water pressure! CEMtobent CS is absolutely radon tight as well as root-resistant! Advantages of CEMtobent Tough and resistant Higher puncture and tear resistance compared to

conventional foils and coating. Quick and easy to install without complicated

welding equipment and specially trained staff, dou-ble lining in one step High compound shear strength The reinforcement fibre structure and thermally

bonded cover layer form a tight composite Can be installed in every season independently of

temperature and weather condition Quality control tests to ensure consistent high

quality Self-healing properties by the pressure of the

swelling bentonite. Seals small cracks in the con-crete by the pressure of the swelling bentonite

No protection layer (protection concrete) has to be on top of the CEMtobent sealing liner. The construction concrete should have direct contact with the open side of the CEMtobent sealing liner. Application CEMtobent is designed for below-ground, vertical and horizontal, structural foundation surfaces. Typical applica-tions include backfilled concrete walls, earth covered roofs, structural slabs, tunnels and property line construc-tion. Property line construction applications include se-cant and contiguous piling, skin wall, metal sheet piling, shotcrete and stabilized earth retention walls. Applica-tions may include structures under continuous or intermit-tent hydrostatic pressure. Where contaminated groundwater or saltwater conditions exist, use CEMtobent CS-Plus with an extra PE-coated geotextile. This extra PE-coated geotextile is also a test-ed and approved root-resistant protection layer. In this particular case (contact with high concentrated saltwater) you have to pre-hydrate CEMtobent with regular tap wa-ter. CEMtobent is resistant to: nitrates, phosphates, chlo-rides, sulfates, lime and organic solvents. Installation in general Install CEMtobent in strict accordance with the manufac-turer’s installation guidelines. Use accessory products as recommended. Also use CEMtobent CS-Plus as required for contaminated conditions.

Installation Guideline of CEMtobent® For CEMtobent DS/CS _________________________________________________________________________________________________________________________________

CEMtobent is not designed to waterproof expansion joints. Expansion joints require a properly engineered expansion joint sealant product. We suggest to use the CEMproof PVC waterstops for expansion joint! We suggest using CEMproof bentonite panels as an additional security for the sealing of expansion joint.

Place CEMtobent over the properly prepared concrete bedding / blinding concrete bed with the dark grey stripe (CEMtobent DS) or with the beige open side (CEMtobent CS-Plus) facing towards the structural concrete to be waterproofed! Overlap all adjoining edges a minimum of 100 mm and stagger ends to a minimum of 300 mm. Staple or nail edges together as required to prevent any displacement before and during concrete pouring. Apply a layer of CEMproof bentonite powder/paste or better CEMtopaste bentonite paste between overlaps.

CEMtobent has to be placed with the open side facing towards the construction concrete which has to be sealed! Detail all penetrations with a 40 mm fillet of CEMtopaste, special bentonite mastic or CEMproof paste (bentonite powder & water) around the penetration on top of the CEMtobent.

CEMtobent should not extend into foundation bearing planes (i.e. pile caps, ground beams, pads, etc.) but should completely envelop them. Where this is not possible/desirable, CEMdicht 3 in 1 mortar (cementi-tious waterproofing by crystallisation) or similar can be used as a conti-nuity ‘membrane’ through the bearing plane, to which CEMtobent can be sealed using a 100 mm lap, incorporating a 5x50 mm fillet of the CEMtopaste. Cut CEMtobent to provide a snug fit around all applicable penetrations (pipes, piles, etc).

CEMtobent can be applied to formed walls in two ways: Mechanically fastening to cast concrete just prior to backfilling (post-applied), or alternative by utilizing the adhesion properties of the CEMtobent (pre-applied on the formwork before concret-ing). Honeycombing or other indentations should be repaired before installing any CEMtobent bentonite liner (post-applied / standard). Fix CEMtobent by using approx. 1 up to 2 shot-fired ‘softwasher’ per square meter vertical wall installation (post-applied)! For Tunnel Construction Sealing please see extra installation manual / installation guidelines!

CEMtobent must always be installed with the open side facing to the concrete which has to be sealed! Expansion joints have to be sealed with an additional expan-sion joint waterstop! Cold joints have to be sealed with QUELLMAX bentonite waterstop tape or with PREDIMAX injection hose system! Terminate CEMtobent at DPC level! Apply a fillet of CEMtopaste, place CEMtobent using fitting rail, cover joint with CEMtopste, and close joints with tape (SealTape). Extend DPC level at least 150 mm over this point.

QUELLMAX Structural concrete, should be placed directly on top of CEMtobent CEMtobent, open side should face to the concrete Natural soil, well compacted Where CEMtobent is terminated below DPC level you shall coat the wall with a waterproof coating at least to DPC level.

Installation Guideline of CEMtobent For CEMtobent DS/CS _________________________________________________________________________________________________________________________________

Notes

System Description CEMtobent is recommended for use under structural reinforced concrete 250 mm thick or greater. Concrete should be well compacted and of the highest quality, the use of well-compacted concrete is recom-mended. Please contact our Technical Department for further information. Surface Preparation The surface must be properly prepared before CEMto-bent is installed. Honeycombing or other indentations should be repaired. Detail all penetration etc. as per method statement. Form-tie holes should be detailed with a stripe of CEMswell hydrophilic rubber (Ø 23 mm) inserted into the centre of the hole and covered with a minimum of 80 mm non-shrink grout. DPC Level CEMtobent is designed for below ground structural waterproofing and should not extent above DPC level. We recommend Soil Testing should be carried out be-fore choosing waterproofing system i.e., CS or DS and that Site Groundwater should be controlled before and during application of membrane and until concrete is fully cured. The following are our preferred application methods to ensure a watertight seal at this point.

If the CEMtobent is to terminate close to the DPC level: Apply a fillet of CEMtopaste to the wall, place CEMto-bent over this fillet by using a fitting rail, fix into position with shot-fired fixings, close the joint with a layer of SealTape or CEMflex Elasto-Tape. Ensure the termination point of the CEMtobent is over-lapped by at least 150mm by the DPC.

If the CEMtobent is to be terminated some distance from the DPC level:

Apply a fillet of CEMtopaste to the wall, place CEMto-bent over this fillet by using a fitting-rail, fix into position with shot-fired fixings, close the joint with a layer of SealTape or CEMflex-Elasto-Tape. CEMdicht 3 in 1 (cementitious waterproofing by crystallisation) has to be used as a continuity “membrane” up to the DPC level. The DPC should overlap this coating by at least 150 mm. Backfilling Backfill with clean well-compacted soil (compacted every 30 cm) that are free from construction debris. Do not use stones or rocks that are larger than 50 mm. Backfill material shall be compactable soils and free of construction debris. Backfill shall be clean, well-graded, and compacted every 300 mm to 90 % modified proctor (as defined by ASTM 1557), and meet these general specifications: No rocks, stones or boulders larger than 50 mm 90 % minimum soil particles smaller than 5 mm 10 % maximum soil particles finer than 74 micron

CEMproof® SilverSeal „active“ SilverSeal swelling non-woven, laminated with PE-membrane. SilverSeal is a light weight, swelling, water-reactive, selfhealing sealing membrane. ______________________________________________________________________________

SilverSeal is a needle-punched non-woven impregnated with water absorbing and water swelling polymer combined with a high density silver-colored PE-membrane

Field of application CEMproof SilverSeal is a waterproofing system, which: • consist of a needle punched non-woven, fully impregnated with water absorbing, water reacting and water swelling polymer • combined with a high density PE – membrane.

SilverSeal is modified especially for the field of structural waterproofing as well as tunnel sealing. The self healing properties of the hydrophilic, waterreactive polymers secure the integrity of the system, even if the PE-membrane, which is on the upstream face, is damaged during installation or backfilling. Penetrating water causes the polymers to swell and thus renders the CEMproof® SilverSeal impermeable. The building structure is permanently protected against penetrating water, even small cracks and voids in the concrete are sealed. CEMproof® SilverSeal can be optimized for the use in salt water!

Technical data sheet

Areas of use CEMproof® SilverSeal is used in all applications, where structures have to be protected against groundwater and seepage. For the waterproofing of foundations, basements, tunnels, garages and any underground / below ground concrete constructions. CEMproof® SilverSeal is an economically and environmentally friendly alternative to synthetic liners, bituminous products and coatings.

Advantages of SilverSeal • Tough and resistant, quick and easy to install, high compound shear strength • Can be installed in every season, independently of temperature and weather condition

• No use of complicated welding equipment and specially trained personnel, overlapping can be easily secured with CEM805 bonding agent • Quality control (CE-Certification) • Self-healing properties of the system based on swelling pressure of the activated swelling polymers • Seals small cracks in the concrete by the pressure of the swelling polymer • Flexibility in roll dimensions (2,00m x 50,00m) • Can be optimized for salt-water usage • Several tests have been made at the University of Braunschweig/Germany and STFI Chemnitz • Easy handling of CEMproof SilverSeal because of the extreme light weight (approx. 500g/m²) • Enormous water absorbing capacity and therefore enormous swelling and sealing capacity because of embedded high swelling absorbing polymer

SilverSeal is very easy to install. SilverSeal swells in contact with water and the hydrophilic polymer swells towards the structural concrete which has to be sealed! A water-circulation between membrane and concrete is not possible. Cracks and voids will be sealed because of the swelling pressure. The swelling polymer may penetrate into concrete cracks and voids.

SilverSeal in combination with prefabricated elements

SilverSeal can be installed during the manufacturing process (pre applied) of prefabricated concrete elements.

SilverSeal can be applied in the factory during the manufacturing process or can be installed on the construction site on the surface of the prefabricated concrete elements.

CEMproof® DualProof DualProof – Durable and watertight solution for below grade concrete structures. _____________________________________________________________________________________ ________________________________________

DualProof DualProof is a fully and permanently bonded, self-adhesive, composite sheet membrane waterproofing system. It consists of a highly flexible PVC membrane laminated with a non-woven PP-fleece. DualProod is cold-applied and pre-applied, as it is installed without heat or open-flames, and before the steel reinforcement is fixed and the concrete is poured. Field of Application General Applications of DualProof Damp-proofing against:

Rising humidity through capillary action Percolating water, for slab-on-ground

foundations, column footings, strip foundations, and walls

diffusion, effusion, sorption Concrete protection against:

Various gases of the ground Different types of chemicals in solution

(sulphate, chloride, carbonate, hydrogen carbonate, etc.)

Contaminated ground water Waterproofing Resistant to:

Water under hydrostatic pressure Lateral water migration for deep, one or multi-

level below grade structures. According to the German DIN 18195

“pressurized water” Additional sealing membrane to all watertight

concrete structures DualProof is an innovative system “Made in Germany” that prevents any lateral water and migration between the waterproofing membrane and the structural concrete. The secret of the high durable watertight solution called CEMproof DualProof is the combination of a special designed non-woven (The new PP FiberTex technology) and a highly flexible PVC-membrane. The manufacturing process is the secret which creates "absolutely watertight bonding with the fresh concrete". This self-adhesive bonding blocks any lateral water migration, even in the event of any local damage to the membrane. The DualProof membrane itself is also connected together with the special designed fleece, that any water circulation in the fleece itself is absolutely impossible. This fleece is also embedded completely into the fresh concrete and creates a full and durable mechanical

bond between the PVC membrane layer of DualProof and the cured concrete. CEMproof DualProof can be used in saltwater areas in order to protect the concrete structure!

Areas of Use CEMproof DualProof is used in all applications, where structures have to be protected against groundwater and seepage. For the waterproofing of foundations, basements, tunnels, garages and all other concrete constructions below grade. CEMproof DualProof is an economically and environmentally friendly alternative to bituminous products and coatings. Advantages of DualProof
