What is Polyurethane Injection Grouting?
Polyurethane grout injection is a specialized waterproofing technique where liquid polyurethane resin is injected into cracks, joints, and gaps in concrete structures under controlled pressure.
When the material comes into contact with water, it expands and forms a flexible waterproof barrier that seals the leakage path.
This polyurethane injection grouting waterproofing method is commonly used to repair:
- Hairline cracks in concrete
- Structural cracks in walls and slabs
- Basement water leaks
- Pipe penetrations and pipe joints
- Expansion joints
- Underground structures
- Retaining walls
- Lift pits and water tanks
The expanding polyurethane effectively blocks water pathways and prevents further seepage.
