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 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 1500 is a CE-certified PU combi injection resin that combines the beneficial properties of S-PU and PU resins. Upon contact with water, it rapidly forms a dense, elastic foam that ensures a permanent seal, but it also cures with constant volume even without water. It is particularly suitable for sealing cracks, cavities/voids, and areas exposed to water.

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 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 270 is a low-viscosity, CE-certified polyacrylate injection gel with very low volume loss during curing. Once cured, it forms a firm, elastic gel that reliably absorbs dynamic and mechanical stresses. It is suitable for crack injection in building components, sealing construction joints, and backfilling joints.

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 4120P is a low-viscosity epoxy injection resin that penetrates even the finest cracks. It cures to a tough, strong finish and, thanks to its high tensile strength and bond strength, enables a durable, structural connection, even under dynamic loads. WEBAC 4120P is used to close, seal, and force-fit cracks and is particularly suitable for components subjected to dynamic loads, such as the foundations of wind turbines.

WEBAC 4130 is a high tensile strength epoxy injection resin that penetrates even the finest cracks and cures to a solid state. High tensile strength and bond strength ensure a durable bond, even on wet or oil-contaminated crack surfaces. It is used to close, seal, and perform structural bonding of cracks and is suitable for solidification of concrete structures as well as for the rehabilitation of foundations, e.g., of wind turbines.

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.

WEBAC 4170T is a CE-certified, very low-viscosity epoxy injection resin that performs well even at low temperatures. It penetrates even the finest cracks, cures to a solid state, and ensures a durable bond—even on dry, damp, or wet crack surfaces—thanks to optimal wetting properties and moisture tolerance. It is used to close, seal, and form a structural bond in cracks and cavities/voids.

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.
