Planning and using waterproofing Protect and preserve value Protecting a building against penetrating moisture, ensuring a pleasant living environment on the interior, and granting the building eternal youth: Accepting these challenges means working with knowledge and precision to implement projects to the satisfaction of the building owner. Living and working in a hygienic environment with a pleasant temperature that is healthy above all else is not a matter of course. To ensure long-term preservation of the value of a building, carefully planned waterproofing solutions are needed. Every building is continuously exposed to external environmental conditions and must be adjusted individually in accordance with the surrounding influences. The waterproofing products and system components must be compatible with each other and matched to suit each other. From substrate preparation to waterproofing for waste water treatment plants and crack waterproofing, SCHOMBURG offers a complete package for every thinkable challenge. Building components in the ground especially require high-quality, professional implementation of waterproofing. Follow-up improvements

or even essential restorations involve high costs and require a lot of time, since after the building pit is filled in, the exterior area is difficult to access. For this reason, SCHOMBURG offers optimised solutions for cellar exterior waterproofing in particular to ensure a water-tight cellar. Selection of matching waterproofing components for cellar masonry depends on a variety of factors. On the one hand, this depends on the use of the cellar, while on the other, various so-called “water impact classes” are involved. In this case, the type and method of penetrating moisture are referred to. Pressing groundwater from outside required another type of waterproofing application than normal ground moisture. The correct application is regulated in the technical documents. This specifies corresponding waterproofing procedures for corresponding water impact classes.
Water impact classes Ground moisture and non pressure water for floor slabs and walls in direct ground These impact classes are present when severely water-permeable ground is present (k > 10-4 m/s) and the measured water level (maximum groundwater/maximum flood level) ≥ 50 cm lies below the lowest
waterproofing level. This impact can be waterproofed using a polymer-modified bituminous thick layer coating (PMBC) or a cementitious, crack-bridging waterproofing slurry (MDS).
Ground moisture and non pressure water for floor slabs and walls in direct ground with drainage These impact classes are present when less water-permeable ground is present (k ≤ 10-4 m/s) and the measured water level (maximum groundwater/maximum flood level) ≥ 50 cm lies below the lowest waterproofing level. The resulting water accumulation is removed by permanently functioning drainage.
If the drainage does not function, pressing water is present. This impact can be waterproofed using a polymer-modified bituminous thick layer coating (PMBC) or a cementitious, crack-bridging waterproofing slurry (MDS).
Moderate exposure to pressure water This impact class is present when groundwater, accumulating water, or flood water affect the component directly in the ground. Up to a water column of ≤ 3 m, the building component may be waterproofed with polymer-modified bituminous thick layer
coating (PMBC). The use of cementitious, crack-bridging waterproofing slurry is not intended for this impact class and may only be agreed to separately with the respective employer.
High exposure to pressure water This impact class is present when groundwater, accumulating water, or flood water affect the component in direct ground and the foundation depth is ≥ 3 m. The impact class distinguishes between two situations. Situation 1: The groundwater and flood water level is beneath the foundation depth.
Situation 2: The groundwater and flood water level is 3 m above the foundation depth. With this exposure, the use of PMBC or flexible polymer-modified thick layer coatings (FPD) are to be agreed separately with the customer.
Non-pressurised water on earth-covered slabs This impact class is present if an earth-covered ceiling is impacted directly by precipitation with a water load of ≤ 10 cm accumulation depth and the measured water level is ≥ 30 cm below the lowest point of the ceiling.
This impact can be waterproofed using a polymer-modified bituminous thick layer coating (PMBC).
Splash water at the wall base and capillary water in and under walls in direct ground The “wall base” describes the area approx. 20 cm below the top edge and approx. 30 cm above the top edge. In this area, the building component must be waterproofed against penetrating moisture with polymer-modified bituminous thick layer coating or a
cementitious, crack-bridging waterproofing slurry. To avoid rising capillary water in walls in direct ground, it is possible to use a cementitious, crack-bridging waterproofing slurry as profile waterproofing.

Preparing substrates For ideal results A sustainably functioning waterproofing requires a thorough and carefully prepared building surface to be treated. After all, the finished waterproofing is only as good as the substrate will allow.
The waterproofing materials must harmonise with the substrate and require the best possible bonding for secure and long-lasting sealing function. For this reason, substrate pretreatment with its specific requirements is particularly important. The technical documents specify the basic principles and details like the evenness, burr removal, and cleaning, as they apply to every user or installer. The ideal pre-treatment of the substrate is based on the respective present waterproofing situation. For example, waterproofing on basement walls requires other procedures than with coatings in garages. Depending on the relevant area, there are different system solutions for the respective application area.
Building condition survey Before any waterproofing measures, a professional building condition analysis of the substrate must be completed. In case of concrete substrates, bubble formation frequently results in the still wet coating. This is due to the air voids that are hardly visible and often covered with concrete paste on the surface of the concrete. The air trapped in the pores expands due to exposure to sunlight and continuously pushes outwards. In this case, the fresh coating is pressed away from the substrate. This is prevented by removing the cement paste layer using diamond grinding or shot blasting. In case of more stubborn concrete paste, sandblasting may even be necessary for clean removal. The open pores may then be filled with suitable mortar or with the right SCHOMBURG waterproofing following application of a primer. Thanks to these work steps, the substrate is pre-treated optimally so that the waterproofing is able to be completed functionally after the drying phase of the mortar.

Substrate preparation with SCHOMBURG products The substrate must be load-bearing, fine-pored, and free of dirt and dust. Unevenness and ridges must be evened out meticulously. As previously discussed in the building condition analysis, open butt joints up to 5 mm and surface profiles and unevenness of stones (e.g. plaster grooves on brickwork or heavy concrete blocks) must be levelled using grouting, e. g. with AQUAFIN-1K. Depressions that are not closed and larger than 5 mm, e.g. mortar pockets or damaged areas must be closed with mortar, e.g. using ASOCRET-M30. Furthermore, the surface must be free of gaping cracks and adhesion inhibiting substances, e.g. oil, paint, laitance layers, and loose components. On the floor slabs, laitance layers must be thoroughly removed mechanically down to the solid core to ensure a high level of bonding. The base slab transition, which is a sensitive, delicate area, should be pre-treated with slurry using AQUAFIN-1K. Next, a coved fillet is applied while still wet using ASOCRET-M30. Alternatively, the coved fillet area can be applied using ASO-Joint-Tape-2000-S together with AQUAFIN-RB400.
After curing completely, the coved fillet area, including 15 cm of the front side, is also covered with AQUAFIN-RB400. The substrate should be pre-wetted so that it is matt damp while applying the waterproofing layer. Strongly absorbent substrates like aerated concrete must be primed with AQUAFIN-Primer for improved adhesion. On metal substrates, use ASODUR-SG3 (including quartz sand sprinkling) as a pore-sealed primer. If ASOCRET-HFF is used to level off the surface in large layer thickness widths (up to 30 mm), the process is the same. If dampness from the rear is expected, then use ASODUR-SG3-superfast instead. Ideal substrates consist of dense concrete, cement-based screeds, P II and P III plaster, and fully grouted masonry work. Formwork and heavy concrete blocks, as well as uneven masonry must be levelled with cement-based mortar.

Cellar exterior waterproofing for new and existing buildings Bituminous thick layer coatings (PMBC) Dry and absolutely sealed basement areas cannot be taken for granted. Optimum exterior basement waterproofing is one of the most important requirements for a building that should be protected from moisture damage in the long term. Because moisture can penetrate basement spaces from a variety of angles, different waterproofing systems are required to produce comprehensive protection and a dry, mould-free living environment.

Retrospective Basement interior waterproofing in existing buildings In the flexible system with radon protection Protection for buildings against extended destruction by water is a central topic of building restoration. Buildings directly in the ground that are not protected against moisture are exposed to decay. A damp wall is also a thermal bridge that can result in subsequent damages. In light of increasing energy costs, a dry wall contributes to the reduction of energy costs. Additional aspects of renovation include improved living comfort and improved real estate value. Retroactive cellar interior waterproofing is the most efficient way to fulfil this requirement.

Retroactive horizontal barrier with liquid injection material In case of damage due to capillary rising moisture, it is possible to apply a horizontal barrier to the masonry work retroactively. Depending on the thickness of the masonry work and the degree of moisture penetration, the pressure injection process may be suitable. In this case, holes featuring a distance from each other of 10–12.5 cm from hole centre to hole centre are drilled into the masonry work. The drilled holes are arranged horizontally in the bearing joint or at an angle of 45°. The drilled hole depth is approximately 5 cm less than the masonry thickness. Corresponding injection packers are used in the pressure process to inject the injection material into the substrate.

COMPONENTS AQUAFIN-1K ASOCRET-BM ASOCRET-M30 AQUAFIN-F
1. Level the wall surface To optimise the distribution of the horizontal barrier, AQUAFIN-1K is applied up to approx. 10 cm above the planned drilled hole depth using brush techniques.
2. F ill voids Fill voids and flaws in the substrate with ASOCRET-BM drilled hole material.
3. Produce the horizontal barrier After drilling the holes (drilled hole distance between 10-12.5 cm), inject AQUAFIN-F with low pressure techniques (<10 bar) into the substrate using injection packers. The injection pressure is maintained until the area near the packer appears glossy-matte. After approx. 24 hours, remove the packers and close the holes with ASOCRET-BM.
4. Alternatively: Pressureless Injection In a pressure-free process, storage containers are engaged in the drilled holes and filled with the injection material. The distribution in the substrate takes place exclusively via gravity and the absorptive behaviour of the substrate. Continue the filling process until no more injection medium is able to be absorbed. Similar to the pressure process, the drilled holes are sealed with the ASOCRET-BM or ASOCRET-M30 drilled hole mortar.

Retroactive horizontal barrier with paste injection material AQUAFIN-i380 is an effective solution for retroactive horizontal barriers. The Silan-based injection cream is processed without any pressure or using the low pressure techniques and has a hydrophobic effect on rising moisture in the masonry work. The material has been tested and certified in accordance with the WTA data sheet (“masonry injection against capillary moisture”) at a penetrating moisture level of 95%. Classic, aqueous horizontal barriers are applied without any pressure up to a penetrating moisture level of < 60%. At a moisture penetration level of > 60%, application using low pressure techniques is recommended. One of the many advantages of AQUAFIN-i380: Even in case of a moisture penetration level up to 95%, this injection cream can be used without any pressure. The active ingredient contained is very fine and highly effective due to its special production technique. It does not react with the water, but rather only with the substrate. AQUAFIN-i380 is hydrophilic and therefore distributes itself especially rapidly in the water present in the masonry work. This will lead to 100% saturation of the pores over time. After the reaction with the substrate, the capillary

have been made water-repellent. Capillary water transportation is prevented and the substrate dries out. The practical 550 ml tubular bag is applied using an injection pistol. Slowly pressing and simultaneously pulling out the injection hose ensures that the drilled holes are filled completely. Due to the creamy consistency, application is also possible on horizontal drilled holes and inhomogeneity in the masonry work. The risk of controlled run off like with aqueous horizontal barriers is omitted.
COMPONENTS AQUAFIN-i380 ASOCRET-BM ASOCRET-M30
1. Drill holes Create drilled holes at a distance of approx. 12.5 cm and a drill angle of 0° — 45° with an electro-pneumatic drill that operates as shudder-free as possible.
2. C lean drilled holes Prior to injection, dust from drilling must be removed thoroughly to ensure maximum possible absorption of the active substance in the masonry work.
3. Produce the horizontal barrier After cleaning the drilled holes, AQUAFIN-i380 is injected using an injection pistol without any pressure. Material must be pressed in until the drilled hole is filled completely. After successful horizontal waterproofing, drilled holes are sealed using ASOCRET-BM or ASOCRET-M30 drilled hole and void filling mortar in accordance with the structure.

Renovation of salt-loaded substrates in the THERMOPAL system Moisture and salt-loaded substrates frequently occur in legacy buildings. For professional and enduring restoration of these surfaces, the existing salt loading must be analysed exactly to ensure that the right product systems can be used. The THERMOPAL system developed for this is not only suitable for surfaces like this, it also supports renovation of formerly mould-contaminated surfaces at the same time. Legacy buildings become completely restored structures.

COMPONENTS ESCO-FLUAT THERMOPAL-SP THERMOPAL-GP11 THERMOPAL-ULTRA-white THERMOPAL-FS33
1. Salt-loaded surface The salts present in the masonry work have a hygroscopic effect and migrate to the surface, since less moisture is present there due to the evaporation zone and good conditions for crystal formation are available there. This causes the plaster surface to decay.
2. A pply salt converter Saturate the exposed masonry work with ESCO-FLUAT one or two times using brush techniques (depending on the salt loading and absorbency of the substrate). Salts that damage the building are transformed into salts that are less soluble and cannot be transmitted to the new, fresh plaster layer.
3. Apply splatterdash coat Apply THERMOPAL-SP drying mortar as semi-covering plaster primer preparation in accordance with plastering technique standards (approx. 50% surface wetting) featuring a layer thickness of max. 5 mm. Pre-wet the substrate lightly as required to ensure good bonding.
4. Apply base plaster In case of larger surface irregularities, THERMOPAL-GP11 is applied in layer thickness from 10 – 30 mm (in multiple layers in case of thicker surfaces). Strike off the previous layer with a plasterer’s darby, and immediately after stiffening, roughen up horizontally and allow to dry.
5. A pply restoration plaster Apply up to max. 3 cm THERMOPALULTRA-white in one application step. After sufficient standing time, the surface may be grid floated or rubbed down.
6. Apply fine plaster (optional) Apply THERMOPAL-FS33 cementitious fine plaster using trowel techniques in the required layer thickness up to max. 3 mm. After drying, remove the surface with a sponge rubber or a felt or sponge board.

Facade impregnation Colour deepening and prevention of fouling Facade impregnation is one of the most frequent procedures involved with the area of building restoration and maintenance. The exterior area of a building is exposed by weathering influences like rain, sunlight, wind, frost, etc. Clean and professionally installed facade impregnation protects the substrate against penetrating water using hydrophobic, water-repellent media. At the same time, the trapped water vapour is able to escape, which permanently avoids moisture damage. Thanks to ASOLIN-SFC45, facades consisting of brick, clinker, natural stone, lime-sand stone, and cementitious plasters are protected sustainably against damaging water influences, successfully treating them within the scope of care and maintenance of existing buildings.

2. A pply impregnation After the façade has dried completely, apply the solvent-free façade cream ASOLIN-SFC45 with a lambskin roller until it fully covers the entire surface. The paste consistency makes very economical, clean, and reliable application possible. A material buffer remains on the substrate during application, which enables very deep penetration of the effective substance into the substrate.

Waterproofing and repair of wastewater treatment plants Cementitious restoration concept Waterproofing and repairs on civic wastewater treatment plants represent very specific requirements for the materials and coatings that are used inside the building. The dirt and rain water that enters into the plant via the sewer system passes through various cleaning stages. Due to the various water qualities, the concrete surfaces are exposed to a variety of chemical stresses. Moisture from the rear and bubble formation due to osmotic pressure are only a part of the resulting damage scenarios. For this reason, water-contacting concrete elements must be permanently protected during repair procedures with specific special primers and water-repellent surface waterproofing.

Waterproofing and repair of process water containers Cementitious restoration concept Whether commercial, industrial, or agricultural purposes are involved, process water must possess specific quality characteristics, depending on the required uses. Irrigation water, for example, must be free of ground and plant-damaging substances, while cooling water may not be allowed to damage devices with lime and algae. In spite of the different components and quality classes involved, all process water has one thing in common: They do not in fact have potable quality, but they still have high demands on the substrates of the respective container. Ideal, building-specific maintenance procedures are able to protect process water containers sustainably and reliably against potential stresses.

Reinforced concrete protects container construction against chemical and mechanical degradation The protection of reinforced concrete components is essential for durability and longevity. Particularly with load-bearing building components such as foundations and pillars, inadequate protection of surfaces and joints can result in significant damage to the structure. Due to high mechanical loads and strong chemical corrosion, the functionality and service life of containers, pools and gutter systems are severely restricted and shortened. In individual cases, the destructive influence is so great that a reduction in the concrete on the surface can be seen after just a few years. Then it is important to carry out the right refurbishment measures at an early stage. The SCHOMBURG system products provide targeted protection against aggressive influences.

COMPONENTS AQUAFIN-P1/-P4 ASOCRET-HS-Flex ASOCRET-BIS-1/6 ASOCRET-BIS-4/40 ASODUR-SG3 ASODUR-SG3-thix ASODUR-V2370
1. Crack restoration Static or water-conducting cracks in the concrete must be sealed professionally (refer to the chapter “Crack restoration”).
2. Level the surface Apply ASOCRET-BIS-1/6 in a single application step up to 6 mm layer thickness on the surface. Application is completed while still wet onto the ASOCRET-HS-Flex adhesive slurry.
3. Create the coved fillet Create a sealing groove in the wall-floor transition using ASODUR-SG3 and quartz sand 0.06 - 1.50 mm in a mix ratio of 3:25 GT. The sealing fillet must be laid while still wet onto the previously applied primer layer of ASODUR-SG3.
4. Transition to the flange structure In the area of the flange structure, apply ASODUR-SG3-thix special pre-primer free of pores over the flange structure with a short-pile wool roller and spread with rough quartz sand immediately. After sufficient curing, further waterproofing measures may be applied.
5. Applying primer Wall: Roll ASODUR-SG3-thix on first equally with a short-pile wool roller, then brush it into the surface zone carefully using a priming brush and then rework it again with the wool roller.
6. Surface protection Apply ASODUR-V2370 by rolling or spraying of a minimum of least two coats. The overcoating time depends on the temperature. Please read the technical data sheet.
Floor: Apply ASODUR-SG3-thix in dollops using a rubber lipped scraper, brush it in thoroughly, and roll it out afterwards.

Crystalline waterproofing Subsequent renovation of reinforced concrete structures Crystalline waterproofing represents a fascinating waterproofing process. After application on the concrete surface, the active substances migrate out of the waterproofing material into the interior of the component, where it promotes crystal growth. The smallest pores and cracks are filled with crystals and are therefore impenetrable by capillary water! “An enemy becomes a friend”: The water penetrating the building component acts as a means of transportation for active substances and carries them deep into the substrate. An additional advantage: AQUAFIN®-IC waterproofing is suitable for drinking water containers!

COMPONENTS FIX 20-T ASOCRET-IM AQUAFIN-IC
1. Open cracks and damaged areas Remove all loose components from the cracked and damaged areas. Break open the static cracks up to a width of at least 20 mm and a depth of at least 25 mm.
2. Immediate waterproofing for water breakthroughs Water breakthroughs are sealed professionally with rapidly hardening cementitious FIX 20-T sealing mortar.
3. Mix the FIX 20-T Mix a powder quantity corresponding with the water breakthrough together with approx. 25% water to produce a homogenous consistency able to be kneaded. Form a suitable plug by hand. Work quickly: The pot life is only approx. 3 minutes!
4. Plugging the water ingress points Press the formed plug into the leak position. Hold the plug firmly in place by hand until it has hardened. Process the plugged position immediately afterwards with a trowel.
5. Improve voids Flawed areas should be improved with FIX 20-T or with ASOCRET-IM.
6. Creating coved fillet Produce the coved fillet with ASOCRET-IM featuring an edge height of approx. 4 cm in the area prepared with still wet AQUAFIN®-IC slurry. After approx. 1–3 hours, rework ASOCRET-IM with AQUAFIN®-IC.
7. Application of AQUAFIN®-IC Dampen all surfaces to be waterproofed with clean water. Apply two layers of AQUAFIN®-IC in the required useful quantity with a roofer’s brush, wide brush, or using spray techniques. Apply the second layer while the first layer is still sticky and has not yet dried out.
8. Retreating existing surfaces The fresh coating must be protected against weathering influences, e.g. sunlight, wind, rain, and frost, etc. The waterproofing layer must be kept damp for at least 3! Complete the first damping after approx. one day.

Vapour barrier for damp substrates In the epoxy resin system Moisture from the rear and high residual moisture on “green” concrete substrates are frequently extremely prone to damage or prolong building time. The ASODURSG2 and ASODUR-SG3 special primers have been used successfully for many years to prevent the damaging influences of rising moisture, and they are also extremely resistant to chemical influences and able to be applied very diversely. In addition to applications on industrial and commercial floor surfaces and in agricultural buildings, use in private home and apartment construction when there is risk of rising damp and valuable floor coverings like natural stone or parquet need to be protected for the long term.

COMPONENTS ASODUR-SG2 ASODUR-SG3
1. Substrate preparation Substrates must be load-bearing and sufficiently firm (concrete class: min. C 20/25 and cement-based screed class min. CT–C35–F5), and free of separating and adhesion-inhibiting substances like paint residues. Depending on the texture of the substrate to be treated, suitable processes must be used, e.g. grinding.
2. C leaning preparations The dust particles resulting from this measure that is taken to prepare the substrate should generally be removed using an industrial vacuum.
4. Rolling on To ensure equal material film on the substrate surface, a suitable lamb’s wool roll should be used to roll the still wet applied material out again equally.
5. Sanding Immediately after applying the material, the wet applied primer layer, and only in case of ASODUR-SG2, should be sanded equally using suitable quartz sand. ASODUR-SG3 does not need to be sanded because a chemical bond results. After hardening, remove loose quartz sand by vacuuming.
3. Material application The correctly mixed 2-component material is applied using a rubber lipped scraper on the pre-wetted substrate (matte damp appearance) and intensively brushed in using scrub brushes.

Foil sealing in new buildings to waterproof concrete Exterior waterproofing with fresh concrete waterproofing membrane Even in classic watertight (waterproof) concrete, cracks, e.g. due to shrinkage and pressure, cannot be ruled out. Water penetrates deeper than planned into the concrete component or, in the case of separating cracks, even into the building. The classic remedy would be to inject resin until the crack closes. It becomes problematic when there is no water, but, for example, the radon gas or water is not always present and we consider inaccessible areas that have already been developed. In these cases, it makes sense to plan the AQUAFIN-WM12 fresh concrete waterproofing membrane as strip waterproofing. Inserted into the formwork, it forms a solid bond with the concrete that prevents water running behind it and forms an additional waterproofing layer.

4. Floor application sequence As the first work step, it is suggested to produce the surrounding edge upstand. After working out the details such as intersections, the surface closure takes place.
5. Wall installation / formwork AQUAFIN-WM12 is installed on the formwork using impact staplers or clips. After stripping the formwork, the wall and floor waterproofing is connected to one another using PVC tape. Then seal tie and installation points with PVC tape.
6. Concrete protection / waterproofing gas / water The fresh concrete waterproofing membrane has a high crack-bridging capacity so that even subsequently appearing cracks in the concrete component do not result in waterproofing problems. The PP fleece laminated to the PVC waterproofing layer creates a solid bond between the strip waterproofing and waterproof concrete that prevents water running behind it.

Integral waterproofing of concrete components With crystalline waterproofing admixture Even in classic watertight (waterproof) concrete, cracks, e.g. due to shrinkage and pressure, cannot be ruled out. Water penetrates deeper than planned into the concrete component or, in the case of separating cracks, even into the building. If the crystalline waterproofing admixture BETOCRETE is planned and used, crystals form on contact with water which can close cracks up to 0.4mm due to the increased and accelerated crack healing ability. Less water enters into the concrete and therefore fewer substances that damage the concrete, such as chlorides, CO2 and chemicals.

Waterproofing of wall surfaces With crack injection During building restoration and repairs, professional crack restoration is indispensable. Cracks result when the stresses influencing the substrate are larger than the resistance of the individual building components. If water penetrates the cracks, then they can place the usefulness of the building in enormous danger. For this reason, crack compression is absolutely necessary to recover the resistance of the substrate. Not only is this possible by filling individual cracks, but also by injecting special injection resins, which spread in the substrate and form a tough elastic foam under the influence of water. This system waterproofs cracks not only temporarily, but sustainably.

COMPONENTS AQUAFIN-P1 AQUAFIN-P4 ASODUR-EKF ASOCRET-BIS-1/6
1. Drilling Cracks that are present are offset at a respective distance of 20 cm at an angle of 45° to the crack.
2. Cleaning Clear any drilling debris that has resulted in the drilled holes using oil-free compressed air.
3. Waterproof water-conducting cracks Insert corresponding injection packer into the drilled holes. Press AQUAFIN-P1 into water-conducting cracks. The material reacts with the water to produce a waterproof, tough elastic foam to stop water penetration. The excess foam is removed after curing so it is flush with the surface.
4. Dam up cracks In case of cracks that do not conduct water, the crack area is insulated using ASODUR-EKF. AQUAFIN-P4 is injected after the insulating material cures completely.
5. P ermanently waterproof cracks During application of AQUAFIN-P1, additional injection using AQUAFIN-P4 elastic crack waterproofing is necessary.
6. Seal drilled holes After the injection resin has hardened, insulation may be removed for visual reasons as required. Seal the drilled holes with ASOCRET-BIS-1/6.

Execution of construction joints in concrete construction With crystalline waterstop sheet In the construction joint, the potential for water ingress due to improper waterproofing is relatively high. Waterproofing with AQUAFIN-CJ5 provides triple security. In addition to the circulation extension of penetrating water, the AQUAFIN-CJ5 waterstop sheet provides further security factors. The cementitious coating forms a strong adhesive bond with the waterproof concrete so that “breaks” and the resulting cracks tend not to occur. However, if the movement of the component results in a crack, the crystalline coating of the waterstop sheet provides support. In the event of contact with water, crystals form and cracks up to 0.4 mm can be sealed.

Execution of construction joints in concrete construction With injection hose system A “white tank” is a structure consisting of concrete with increased resistance to penetrating water. These parts are normally partially or completely in direct ground. The concrete assumes a load-bearing as well as sealing function without additional waterproofing measures. During building construction, concrete sections result in construction joints that must be waterproofed against groundwater and moisture using special procedures. The advance installation of an injection hose made of PVC has also proved to be an effective system. The injection of resin that distributes itself throughout the complete area of the joint and any possible voids throughout the concrete makes it possible retroactively to waterproof the concrete quickly and easily without costly work steps.

Execution of construction joints in concrete construction With swelling joint tape Another successful variation for waterproofing concrete construction joints is the use of so-called swelling rubber. Elastomer swelling tape consists of a special plastic and special filler materials, and they also react to water contact with strong and reliable swelling behaviour. Compared to swelling joint tape made of bentonite, elastomer joint tape has the advantage that it swells in a “form-stable” manner in contact with water (> 700%) and therefore cannot be washed out. The area of application includes construction joint waterproofing in in-situ concrete walls and element walls, joints that are constantly or temporarily exposed to loading from ground, slope, and/or surface water. Use is also possible in water exchange areas.

Joint and feature waterproofing with joint sealing tapes Every component features corners, edges, and intersections in the form of pipes, channels, screws, and dowels that need to be waterproofed. An essential aspect of protection of buildings against dampness is also the integration of detail points like floor drains, wall-floor transition joints, or building component joints using joint tape. Additionally, joint tapes need to absorb and dissipate possible movements and stresses from the substrate reliably so that damage cannot result.
