Armgrout Inject PU1
Armgrout Inject PU1 is a single-component, hydrophilic polyurethane injection resin for stopping active water leaks in concrete structures. On contact with water, the resin rapidly expands and forms a tough, closed-cell foam that seals cracks, joints, and voids - even under flowing water conditions. It is widely used to stop leaks in tunnels, basements, underground parking, water tanks, and construction joints.
The product is injected under low pressure into pre-drilled holes adjacent to the crack, expanding to fill the full crack width and depth. Once cured, the foam is permanent, waterproof, and chemically resistant to the alkaline concrete environment.
Key Features
- Hydrophilic foam - reacts with water to expand and seal leaks

- Expansion ratio up to 20× original volume
- Permanent, flexible seal after curing
