Abstract
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.
Claims38
A damp proofing and/or waterproofing process comprising:
- adhering to a belowgrade surface of a structure a thermoplastic polyurethane (TPU) membrane having a thickness of from about 0.002 inches to about 0.018 inches and capable of withstanding a hydrostatic pressure of at least about 20 psi.
One of a building foundation, building basement, reservoir, ornamental pool, pond, plaza deck, parking deck, walkway, tunnel, earthen shelter, bridge abutment, retaining wall, landfill, chemical canal and water canal having adhered to a belowgrade surface thereof a thermoplastic polyurethane (TPU) membrane having a thickness of from about 0.002 inches to about 0.018 inches and capable of withstanding a hydrostatic pressure of at least about 20 psi.
A process for reducing ingress of water into a structure comprising:
- adhering to a belowgrade surface of the structure a thermoplastic polyurethane (TPU) membrane having a thickness of from about 0.002 inches to about 0.018 inches and capable of withstanding a hydrostatic pressure of at least about 20 psi.
A process for reducing ingress of at least one of radon, molds, fungi, salts and pesticides into a structure comprising:
- adhering to a belowgrade surface of the structure a thermoplastic polyurethane (TPU) membrane having a thickness of from about 0.002 inches to about 0.018 inches and capable of withstanding a hydrostatic pressure of at least about 20 psi.
