WEBAC® 4170T
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 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).
