Polyurethane (PU) injection grout is a versatile material used primarily for sealing and repairing cracks in structures, stabilizing soil, and filling voids. Here are some key points about PU injection grout:
1. **Composition**: PU injection grout is made from polyurethane resins that react with water or moisture to expand and fill gaps. This characteristic makes it particularly effective in waterproofing and soil stabilization.
2. **Applications**:
- **Crack Repair**: It's commonly used to repair cracks in concrete structures, such as foundations, walls, and floors.
- **Soil Stabilization**: PU grout can be injected into the ground to stabilize loose or shifting soil, making it ideal for construction projects.
- **Waterproofing**: It is often used to seal leaks in basements, tunnels, and other structures exposed to water.
3. **Advantages**:
- **Fast Curing**: PU grout cures quickly, allowing for fast repairs and minimal downtime.
- **Flexibility**: It can accommodate
