WEBAC® 1660
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 injection packers are filling nozzles that serve as a connecting element between the injection pump and the structural component. They are available in various designs—such as Drill hole packers or surface packers—depending on the type of injection material and the requirements of the structural component. The packers are characterized by secure attachment within the structural element as well as high pressure and corrosion resistance (stainless steel or aluminum versions).
