PU injection grouting involves injecting polyurethane resin into cracks or voids in concrete structures. The resin reacts with water to form an expanding foam, sealing leaks and preventing further water ingress.
Benefits:
- Rapid water stop and crack sealing.
- Non-invasive and minimal surface disruption.
- Flexible solution for active leaks.
- Strengthens the structure along with waterproofing.
Applications / Use Cases:
- Basements and underground structures.
- Tunnels, dams, and water tanks.
- Industrial and commercial buildings.
- Concrete cracks in bridges and flyovers.
