WEBAC® 1405
WEBAC 1405 is a low-viscosity, CE-certified PU injection resin. It cures with constant volume to form an elastic, limited-elasticity resin. Upon contact with water, it forms a uniform, closed, and watertight pore structure. It is used for closing, sealing, and limited-elasticity filling of dry, damp, or water-bearing cracks, as well as for sealing cavities/voids in building construction, civil engineering, bridge construction, tunnel construction, and shaft construction.

WEBAC B14 is a hardener for certain PU injection resins. It shortens the pot life and curing 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).
Injection Tubes
WEBAC® Injection Tube
View detailsWEBAC injection tubes are flexible joint tubes that, when used in conjunction with WEBAC PU injection resins, provide a reliable seal. They are used to seal construction joints in concrete structures and to create a structural bond between concrete components.
