Polyurethane grouting resins of GEOPUR type have closed pore cell structure and therefore are impermeable for water.

Examples of use as a sealing material:

• stopping of water inflows into subsurface constructions - tunnels, cellars etc.

• repair of damaged waterproofing insulation of underground constructions

• repair of concrete structures at water works

• repair of soil dams - sealing of seepages through the dam

• remediation of environmental accidents - stopping of contaminants spreading by constructing an impermeable underground barrier
