Stabilization of Structures

WEBAC 155 is a moisture-curing, 1C polyurethane (PU) injection resin that is ready for immediate use without mixing or a catalyst. Upon contact with water, it reacts to form an elastic, surface-tight foam that reliably and permanently seals cracks and cavities/voids. This makes WEBAC 155 particularly suitable for crack injection, masonry waterproofing, and building waterproofing, even against rising water.

WEBAC 1610 is a high-strength PU injection resin whose compressive and bending tensile strength is specifically designed for structural bonding in masonry. When mixed with water, it foams slightly; however, under dry conditions, it cures without foaming into a compact, waterproof material. It is suitable for sealing, solidification, and structural bonding of building components, as well as for filling cavities/voids, and is specifically designed for use in masonry.

WEBAC 1660 is a CE-certified PU injection resin with high compressive and bending tensile strength. It foams slightly upon contact with water and, under dry conditions, cures into a virtually pore-free, solid, and waterproof material. It is used for sealing, bonding, and structural solidification of concrete and masonry; for filling cavities/voids and gravel pockets; and for structural bonding of dry voids in rubble masonry and loose rock.

WEBAC 2061 is a very low-viscosity, water-resistant silicate injection solution. It reacts to form a chemically resistant, solidified structure and is suitable for stabilizing and solidifying non-cohesive to weakly cohesive soils and masonry. 

WEBAC 240 is a low-viscosity, fast-setting polyacrylate injection gel with National Technical Approval from DIBt (B-concentration 2%). After curing, it forms a waterproof, firm-elastic gel that reliably absorbs dynamic and mechanical stresses. It is particularly suitable for curtain injection—either in the subsoil immediately adjacent to the structural element or within the existing building structure—as well as for subsoil stabilization and waterproofing or damp proof courses (dpc).

WEBAC 4110 is a CE-certified, low-viscosity epoxy injection resin. This allows the resin to penetrate even the finest cracks and crack branches, enabling a permanent bond in concrete and masonry structures. After application, it cures with constant volume to form a solid material with high tensile strength and inherent strength, as well as excellent edge adhesion. It is used to close, seal, and perform structural bonding of dry cracks in concrete components, as well as for injection of construction joints.

WEBAC 4170 is a CE-certified, very low-viscosity epoxy injection resin with good penetration. It penetrates even the finest cracks, cures to a solid state, and ensures a durable bond through optimal wetting and adhesion, even on dry or wet crack surfaces. It is used for closing, sealing, and structural force-fitting of structural components and is also suitable for crack filling.

WEBAC 4170E is a very low-viscosity epoxy injection resin with excellent penetration properties. It penetrates even the finest cracks, cures to a solid state, and, thanks to its excellent wetting and adhesion properties, ensures a durable bond on both dry and damp crack surfaces. It is used for sealing, waterproofing, and creating a structural bond between structural components, as well as for crack filling.

The WEBAC IP 2K-PU is an air-powered 2C double-piston pump designed for dispensing polyurethane resins in a 1:1 mixing ratio. It is characterized by high dispensing accuracy and a robust, site-ready design, and is available with a variety of connection systems and mixing heads. The pump is used for the sealing of foundation pits, as well as for ground injection and the backfilling of cavities/voids.
