Advantages
- One component hydrophilic PUR resin, additional waterproofing due to post-expansion.
- Fast reaction with an immediate increase of viscosity.
- Can be injected as 1 component or 2 component in combination with water, maximum amount of water = 200%.
- Foam factor 6-8x.
- 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.
