Estimating the term…
The present invention provides processes for damp proofing and 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 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, and may greatly reduce or even prevent the ingress of water and the concomitant entry of waterborne molds, fungi, salts and other pollutants such as pesticides and radon into those structures.
A damp proofing process comprising:
A waterproofing process comprising:
A process for reducing ingress of at least one of water, radon, molds, fungi, salts and pesticides into a structure comprising:
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 0.0508 mm (0.002 in.) to about 0.457 mm (0.018 in.) and capable of withstanding a hydrostatic pressure of at least about 138 kPa (20 psi).
