Belowgrade damp proofing and/or waterproofing with thermoplastic polyurethane (TPU)

摘要

The present invention provides processes for damp proofing and/or waterproofing structures by the adhesion of a thin thermoplastic polyurethane (TPU) membrane to a belowgrade surface structure. The inventive processes may find application in the damp proofing and/or waterproofing of belowgrade structures such as building foundations and basements, reservoirs, ornamental pools, ponds, plaza decks, parking decks, walkways, tunnels, earthen shelters, bridge abutments, retaining walls, landfills and water/chemical canals.
