Method for protecting waterproofed substrate surfaces and structures for accomplishing same

摘要

Method for waterproofing and protecting a water-penetrable surface comprises the steps of applying a waterproofing agent (12), preferably a preformed waterproofing laminate comprising a waterproofing composition membrane layer (14) and a carrier support sheet (16), onto a substrate surface (10) such as a sub-grade vertical concrete wall, and subsequently placing against the waterproofed surface a protective non-friable extruded thermoplastic synthetic polymer sheet (18). The extruded sheet may comprise virgin or scrap thermoplastic polymer materials such as polyethylene, polypropylene, a polyamide, or a combination thereof and may be a foamed material. Scrap materials may be cross-linked or even highly cross-linked. Waterproofing structures associated with the method are also disclosed.
