WEBAC® 1420
WEBAC 1420 is a highly flexible, tear-resistant PU injection resin designed for areas subject to severe biological and chemical stress. Upon contact with water, it rapidly reacts to form a dimensionally stable foam structure and cures into an elastic, volume-stable resin with good elongation. It is suitable for sealing, waterproofing, and making limited-elasticity joints in building components, as well as for sealing water-bearing cracks in both dry and wet areas.

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).
