Product Description
Product Overview
VPU-1 is a single-component hydrophilic polyurethane grouting material designed for waterproof plugging and reinforcement repair of concrete leakage. This fast-curing water-soluble formulation reacts rapidly with water to form a milky white elastic colloid that expands within cracks, providing immediate water sealing.
Key Characteristics
- Low viscosity (150-350 mpa.s) with rapid water reaction for quick sealing
- Forms ivory elastic colloidal concretion with high compressive strength and low temperature resistance
- Excellent penetration capability for deep crack sealing
- Adjustable viscosity and curing speed (10-100 seconds) to meet specific requirements
- Good dilatability with 500-1000% foaming capacity

Polyurethane Grouting Material Comparison
VPU-1 (Hydrophilic) vs VPU-2 (Hydrophobic)
| Feature | VPU-1 Hydrophilic | VPU-2 Hydrophobic |
|---|---|---|
| Reaction Time | 10-20 seconds | 15-20 minutes |
| Waterproof Mechanism | Reacts with water to form solid state | Foaming, displacing water without reaction |
| Key Advantages | Fast response speed, relatively low price | No shrinkage, excellent stability |
| Construction Environment | No restrictions - dry, wet, or open water | More stable performance with lower shrinkage |
Application Methods
Polyurethane grouting employs two primary methods: low-pressure injection for standard applications and high-pressure injection for areas with significant water flow. The process involves drilling holes and injecting the liquid polymer, which expands to fill voids and cracks completely.
Application Scope
- Construction deformation joints and structural cracks
- Underground tunnels including subway systems and railway tunnels
- Ports, wharves, bridge piers, and dam structures
- Geological drilling retention walls and mining water control
