Solvent free, flexible, extremely low viscosity polyurethane for elastically sealing very fine cracks and construction joints in building structures. KÖSTER IN 4 is permanently elastic and flexible at low temperatures.
Fields of application: waterproofing of fine cracks, construction joints, hose injection, or for solidifying porous building structures.
Consumption: Approx. 1.1 kg/l void
10 kg combipackage (IN 240 010)
Low viscosity acrylic gel for curtain injection as well as area injection of masonry and concrete. Water based, elastic gel with a very low starting viscosity after initial mixing. It is capable of binding water during gelation. The swelling ability after full curing allows a 40% uptake of additional water into the gel structure. Due to the low starting viscosity, it can be injected into fine substrate pores. KÖSTER Injection Gel G4 is drinking water and non-toxic ground water interaction certified.
Consumption: Depends on the field of application.
Elastic PU injection resin. For permenantly waterproofing cracks and joints. It is designed to withstand continuous contraction and expansion and is therefore ideal for the repair of moving cracks. Also suitable for slightly damp cracks. Viscosity approx. 200 mPa.s.
Fields of application: In combination with KÖSTER IN 8 for the permanent, elastic sealing of water bearing cracks and joints. Without pre-injection for the sealing of dry cracks, joints and voids. KÖSTER IN 2 is used in cases where future movements of the building structure can not be excluded.
Consumption: Approx. 1.1 kg/l void
1 kg combipackage (IN 220 001)
8 kg combipackage (IN 220 008)
40 kg combipackage (IN 220 040)
Broadly applicable PU injection resin for dry and water bearing cracks. The specialty: KÖSTER 2 IN 1 forms an elastic foam when coming into contact with water which pushes the water out of the crack. If no water is present the material forms an elastic solid body resin and permanently seals the crack.
Fields of application: Waterproofing of water bearing and permanently sealing dry cracks in masonry and concrete. Tested according to EN 1504.
Consumption: Approx. 0.1 kg / l void (foam), approx. 1.1 kg / l void (solid resin)
1 kg combipackage (IN 201 001)
5 kg combipackage (IN 201 005)
20 kg combipackage (IN 201 020)
