Bulk Waterproofing PU Grouting Material Water Soluble Polyurethane Grouting Liquid

This advanced polyurethane grouting material is manufactured using imported foreign technology. When mixed with water, it rapidly foams, expands, and solidifies into a high-elasticity, high-toughness gel with low shrinkage and dense structure. The product features superior self-repairing capabilities through repeated foaming with water, providing waterproofing and leakage-stopping effectiveness 2-3 times greater than traditional materials.

Drill holes at drip points using a high-pressure grouting machine and fill with water-stopping needles for grouting and plugging. For areas with large voids during settlement and crack sealing, inject polymer cement slurry first, then apply the sealing material after the cement slurry solidifies.

Standard test conditions: (23 ± 2) ℃
