Polyurethane Leak Sealing Explained
Shut off water leaks in concrete, brickwork and sewers where movement and settlement may occur.
Water cut-off of water leaks in foundations such as diaphragm walls, piling sheets and secant piles.
Sealing water-carrying cracks and joints in tunnel segments.
Curtain grouting behind tunnel, concrete, brickwork and sewer walls.
Injection of water cut-off membranes and liners in tunnels.
Different reaction times are possible by adjusting the percentage of GEN ACC Accelerator.
The closed-cell structure of cured polyurethane ensures permanent flexible sealing of cracks and joints.
Cured polyurethane is flexible, shrink-free and exhibits good chemical resistance (contact our Technical Service for chemical resistance).
Cured polyurethane is harmless for the environment and resistant to biological attacks.
