Description & Applications
Rajguru PU Injection Grout is a single-component solvent-free MDI-based polyurethane resin that reacts vigorously upon contact with water. Formulated for 250-bar high-pressure injection through mechanical packers, it expands into a dense, closed-cell elastomeric foam that instantly seals running leaks in concrete cracks and construction joints.
Key Engineering Benefits
- Instant water stop: terminates heavy gushing water ingress in under 90 seconds
- Low viscosity liquid penetrates deep into micro-cracks down to 0.15mm width
- Closed-cell foam matrix does not shrink or dry out even after water recedes
- Elastomeric flexibility accommodates ongoing thermal and dynamic crack movements
Recommended Applications
- Sealing active water leaks in basement retaining walls, elevator pits, and raft slabs
- Underground metro tunnels, cross passages, and utility box culvert joint sealing
- Water treatment plant aeration tanks, dams, spillways, and intake towers
- Expansion joint and cold construction joint leak remediation without excavation

A torch-on system is three layers, not one product
Coverage and consumption on this page are for the membrane alone. A tanked roof or basement needs the primer under it and a protection layer over it, and the three are specified together.
