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, sewer walls, and sheet piling.
  • Automatic sewer injections with packer systems.
  • Soil stabilization.
  • Injection of water cut-off membranes and liners in tunnels.

Advantages

  • One component hydrophilic polyurethane resin, additional mechanical water shut-off through expansion after curing.
  • Can be injected as one component or two component in combination with water.
  • Depending on the amount of water added, a rubbery foam (200 to 500%) or stable polyurethane gel (500 to 700%) is formed.
  • Cured polyurethane is highly flexible, ideally suited for structures where a high degree of settlement and movement can occur.
  • Cured polyurethane is harmless for the environment and resistant to biological attacks.
