The invention is a hydrophobic polyurethane foam prepared from a conventional PO/EO polyether polyol, a graft polyol and a hydrophobicity inducing surfactant. The foam is sufficiently hydrophobic to pass a stringent water impermeability test.
Application scope:
1. For the crack, flexing crack, construction crack, and instruction crack of building and concrete project.
2. Leak stopping for the breast wall of artesian well in geologic drilling project.
3. Grouting of reservoir and dam for the water conservancy project, leak stopping of the water transporting tunnel, seepage control of the concrete crack of the embankment.
4. Leak stopping for underground, tunnel, culvert, sewage disposing pool, concrete fissure.
5. Leak stopping for basement, underground garage, and underground channels.
6. Leak stopping for floor, wall pipe, and wall corner.
7. Cracking of building, girder, pole, board etc structure, inject epoxy resin with high-handed.
