WPU is one component hydrophilic water-soluble polyurethane grouting material react with water rapidly to be solidified and expansion to sealing the crack.
Large water envlope
Active crack suitable
1. Good hydrophilic, water quick dispersion reaction happened or foam expansion, permanently sealing the water by form as elastic colloidal with sand and stone.
2. Can adjust the curing time, from several seconds to several minutes.
3. Good expansion, good performance of reaction with large volume water.
4. Easy grouting , even in low temperature
5. Single Component, easy construction, easy cleaning.
