ArmGrout Inject PU1 is a ready to use, highly reactive, one component polyurethane based modified isocyanate injection resin used for stoppage of water inflows from cracks and joints and for compacting loose stones. It foams with a high increase in volume on contact with water and becomes a viscoelastic firm foam which seals temporarily against further water penetration. On very dry surfaces it does not foam immediately but hardens slowly.

Key features

• Foams with high volume increase on contact with water, forming a viscoelastic firm foam that seals temporarily
• Resistant against acids and lyes
• On very dry surfaces hardens slowly without immediate foaming
• Ready to use, one component

Applications

• Injection of water-bearing cracks and joints in concrete and stone
• Stoppage of water inflows from cracks, joints etc.
• Compacting of loose stones
