Sewer Repair

WEBAC 1403P is a CE-certified, low-viscosity PU injection resin with high chemical resistance. Upon contact with water, it forms a uniform, closed, and watertight pore structure and cures into a resin with constant volume. It is suitable for sealing, waterproofing, and limited-expansion filling of dry, damp, or water-bearing cracks, as well as for injection of injection tubes in construction joints.

WEBAC 1420 is a highly flexible, tear-resistant PU injection resin designed for areas subject to severe biological and chemical stress. Upon contact with water, it rapidly reacts to form a dimensionally stable foam structure and cures into an elastic, volume-stable resin with good elongation. It is suitable for sealing, waterproofing, and making limited-elasticity joints in building components, as well as for sealing water-bearing cracks in both dry and wet areas.

WEBAC 150 is a versatile PU injection foam resin (SPU) that is particularly valued for its safe and easy application. Upon contact with water, it cures with significant expansion to form a surface-tight, firm-elastic foam with a very fine-cell structure. This makes it suitable for the rapid, temporary closure and sealing of pressurized water-bearing cracks, cavities/voids, and leaks in building construction, civil engineering, bridge construction, and tunnel construction.

WEBAC 157 is an elastic PU injection foam resin (SPU) with a very fine-pored foam structure. Upon contact with water, this low-viscosity material forms a surface-tight, adaptable foam. It is suitable for temporarily closing, sealing, and filling cracks, cavities/voids, and gaps in masonry, concrete, and natural stone—e.g., in shaft construction and water management structures—and can also be used where there is limited movement of structural components.

WEBAC 2260 is a slow-expanding, thermally insulating PU casting foam resin. It cures into a pressure-resistant, non-brittle rigid foam with a fine-pored, closed-cell, and hydrophobic structure. It is used to fill voids, cracks, and gaps, e.g., in double-shell masonry or around pipe penetrations, and also serves as a sealant.

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 240 + Bseal I is a polymer-reinforced polyacrylate injection gel with excellent adhesion to dry, damp, and wet substrates, as well as to foils and membranes. After curing, the gel remains dimensionally stable and exhibits very little volume loss. Thanks to its elasticity and adhesive strength, it is suitable for sealing expansion joints, damaged sheet and membrane waterproofing, as well as for sealing annular gaps in tunnel lining construction. 

WEBAC 4515 is an epoxy putty that is easy and efficient to apply. It cures quickly, even at temperatures as low as -5 °C, and achieves high compressive strength. It is particularly suitable for use in crack sealing and for the installation of surface packers.

WEBAC 4525 is a non-drip, universal epoxy putty. It cures into a solid mass with high chemical resistance and can be applied even on damp substrates and in areas exposed to water. It is particularly suitable for bonding mineral building materials and for crack sealing.

WEBAC 4530 is a versatile epoxy putty that is particularly valued for its ease of application. It cures into a strong, durable compound and can be mixed with quartz sand as needed to supplement concrete. The material offers excellent adhesion to concrete, mineral substrates, and stoneware. It is particularly suitable for repair and bonding work in sewer and building renovation, as well as for the installation of surface packers.

WEBAC 4535 is a versatile epoxy putty that cures quickly into a strong, durable compound and can be mixed with quartz sand as needed to supplement concrete. The material offers excellent adhesion to concrete, mineral substrates, and stoneware. It is particularly suitable for repair and bonding work in sewer and building renovation, as well as for the installation of surface packers.

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.
