TamPur 150 Polyurethane Injection Grout (PU Grout)
TamPur 150 is a single-component hydrophilic polyurethane injection grout combined with polyether polyols. It only reacts on contact with water and forms a flexible polyurethane seal. It can be injected directly into leaking cracks, fractures or joints, or injected 1:1 with water. After injection, TamPur 150 foams to expand and fill the void, forming a tight, impermeable elastomeric seal that stops the water flow.

Applications
- Injected directly into leaking cracks, fractures or joints for structural water stopping
- Can be mixed 1:1 with water to fill water-bearing voids
- Water stopping and sealing of underground structures (tunnels, foundations, mines)
- Reacts and seals in seawater or mineral water environments
Advantages
- Potable water certified
- High tensile adhesion for long-lasting water stopping
- Solvent-free and environmentally safe
- Excellent adhesion to concrete, brick, mortar and most surfaces
- Resistant to most organic solvents, mild acids and alkalis
- Rapidly forms a highly resilient flexible seal that allows movement of cracks
- Reacts even with seawater or mineral water
