Single Component Polyurethane Grouting Fluid Material
Single Component • Water-Soluble • Polyurethane Grouting Fluid 
Single Component Hydrophilic Polyurethane Grouting fluid is a polymer chemical grouting material made from hydrophilic polyether polyols and Isocyanate. The material reacts with water to form an elastic colloidal solid, achieving excellent water-stopping effects. It is a new high-pressure grouting material for waterproofing and leak-stopping applications.
This product is manufactured using advanced foreign technology. Polyurethane grouting material forms a high elasticity and toughness gel with low shrinkage and compact structure after mixing with water, rapidly foaming, expanding and solidifying. This product features superior self-repairing functionality through repeated foaming with water, providing waterproof and leak-stopping effectiveness 2-3 times greater than traditional materials.
Product Features
- Immediate chemical reaction with water, self-dispersing, emulsifying and foaming to form impermeable elastic colloidal solid with excellent water-stopping performance
- Quick response, high strength and strong packing capability
- Gas pressure assists in pressing grout into structural voids, completely filling and compacting porous structures
- Excellent swelling properties, large water inclusion capacity, good hydrophilicity and filling characteristics
- Adjustable viscosity and curing speed according to project requirements

Note: When conducting water-based central control, a water inclusion test should be conducted first. If abnormal situations occur (white spots, translucency, or inability to contain water), the product is judged as unqualified, and -NCO content should be measured simultaneously.
Application
- Sealing leaks in various buildings and underground concrete engineering cracks, expansion joints, construction joints, and structural joints
- Water shut-off in tunnel roofs and broken layer reinforcement for coal mining and other mining projects
- Bridge foundation strengthening and bridge crack repair
Safety Notes
- Wear protective equipment (gloves, goggles) during construction to avoid direct skin contact. If contamination occurs, wash with plenty of water
- Store in cool locations. Construction requires proper ventilation and must be kept away from fire sources until material is fully solidified
Product Packaging
- Stored in clean, dry and sealed iron drums
- Transport according to regular product requirements - prevent rain, exposure, squeezing, and collision while ensuring packaging integrity
- Store in ventilated, dry and cool locations, away from direct sunlight and rain. Storage temperature should not exceed 40℃
- Shelf life: 9 months under normal storage conditions
