WEBAC® 250
WEBAC 250 is a very low-viscosity polyacrylate injection gel with excellent penetrating ability that penetrates even the finest pores of mineral substrates. After curing, it hardens into a waterproof, firm-elastic gel with high elasticity and good adhesion to both dry and wet substrates. It is particularly suitable for post-construction damp proof courses (dpc) and for large-area waterproofing in masonry.

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).
