WEBAC® 4130
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 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).
