- Classic Line
WEBAC® 4120P
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.

Injection Packers
WEBAC® Injection Packers

View detailsWEBAC 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).
