Fields of application include waterproofing of civil engineering stuctures and corrosion protection of concete exposed to moderate chemical stresses |
 | Crack bridging, flexible polyurethane based sealant for horizontal and vertical concrete substrates. KÖSTER PUR-Bitumen is waterproof and highly resistant against mechanical stresses, seawater, salt solutions, inorganic and organic acids and bases. Brush-, roll- and sprayable. Fields of application include crack bridging waterproofing of civil engineering structures, crack bridging corrosion protection for concrete exposed to moderate chemical stresses. |
 | KÖSTER VE is a vinyl ester mortar with very good adhesion to all mineral substrates and to stainless steel. It is perfectly suited for the protection of surfaces in facilities with high chemical and mechanical demands on the coatings such as agricultural concrete elements, waste treatment plants, and chimneys. |
 | Water activated polyurethane gel which can be used for curtain and area injection as well as for retroactive waterproofing of dilatation joints. Depending on the amount of water added, a highly elastic waterproof mass or respectively foam hydro gel is formed. It does not promote corrosion and is solvent-free.
Fields of application for KÖSTER PUR Gel include retroactive external waterproofing of areas with ground contact (curtain injection), injections in highly porous, jointed and cracked building materials (area injection) as well as for the sealing of cavities, pipe couplings, pipe and cable penetration, and joints in masonry, concrete and soils |
 | Water activated hydrophobic PU injection foam. The material only reacts when it comes in contact with water and immediately forms a stif f, waterproof polyurethane foam. Volume expansion up to 30 times. Free of solvents and fillers, resistant to hydrolysis.
Fields of application: waterproofing water bearing cracks in concrete and masonry.
|
 | Broadly applicable solvent-free PU injection resin for dry and water bearing cracks. The specialty: KÖSTER KB-Pur® 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. |
 | 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 KB-Pur® IN 1 for permanently an elastically sealing water bearing cracks and joints. Without pre-injection for the sealing of dry cracks, joints and voids. KÖSTER KB-Pur® IN 2 is used in cases where future movements of the building structure can not be excluded. |
 | 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. The HT version is suited for use in high temperature climates.
Fields of application: In combination with KÖSTER KB-Pur® IN 1 for permanently and elastically sealing water bearing cracks and joints. Without pre-injection for the sealing of dry cracks, joints and voids. KÖSTER KB-Pur® IN 2 is used in cases where future movements of the building structure can not be excluded. |
