Available Size
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.
