WEBAC® 1403
WEBAC 1403 is a long-track-record proven PU injection resin, particularly valued for its safe and controlled application. Upon contact with water, it cures into a closed, waterproof, and dimensionally stable resin with a fine pore structure. It is suitable for sealing, crack injection, and stabilizing masonry and concrete, and is used for post-construction damp proof courses (dpc) against capillary rising damp.

- Damp proof course (dpc) in masonry
- Sealing of joint tapes
- Sealing seepages in concrete
- Sealing of construction joints (waterproofing of gravel nests/honey combs) and connection joints of precast walls
- Sealing of foundation pits
- Sealing injection in open-pored concrete structures (e.g. tamped concrete)
Properties

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).
