| 摘要 |
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.
