Polyurethane Leak Sealing Explained

Applications

  • 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.

Advantages

  • One component.
  • 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.
  • Certified To NSF 61-5 (approved for contact with drinking water).
