- Classic Line
WEBAC® 1500
WEBAC 1500 is a CE-certified PU combi injection resin that combines the beneficial properties of S-PU and PU resins. Upon contact with water, it rapidly forms a dense, elastic foam that ensures a permanent seal, but it also cures with constant volume even without water. It is particularly suitable for sealing cracks, cavities/voids, and areas exposed to water.

WEBAC B15 is a universal accelerator for PU injection foam resins and PU combination injection resins. It shortens the foaming reaction time of these resins and is particularly recommended for use at low temperatures.
Injection Packers
WEBAC® Injection Packers
- Classic Line
- Consolidation Line
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).
