WEBAC® 1440
WEBAC 1440 is a highly flexible PU injection resin that forms a tear-resistant foam structure and is particularly suitable for structures with cavities/voids. It cures with constant volume to form a chemically highly resistant resin that stabilizes porous masonry and increases its strength and waterproofing properties. It is used for closing, sealing, and creating limited-elasticity joints between building components and is suitable as a post-construction damp proof course (dpc) against capillary rising damp in various types of 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).
