Sika SikaInject-155 Single-Component Polyurethane Injection Resin (Injection Water)
SikaInject-155 (formerly MasterRoc MP 355 1K) is a solvent-free single-component polyurethane foam that reacts on contact with moisture or water. The system comprises a base resin and an accelerator (catalyst, CAT).

Applications
- Stopping small-to-medium water ingress in underground structures (tunnels, mines, foundations)
- Filling water-bearing voids
- Reacts in humid environments with good adhesion to damp surfaces
Advantages
- Reacts with water — foams and cures on contact with moisture or water, suitable for stopping water in dynamic water environments
- Single-component application — no on-site mixing of resin and hardener, simple operation
- Filling and water stopping in one — effectively fills water-bearing voids and stops small-to-medium flow leakage
- Strong adhesion — good bond even on damp surfaces
