摘要:
Disclosed is a waterproofing membrane that comprises a carrier sheet (layer A); a waterproofing adhesive (layer B); a protective coating (layer C), wherein the protective coating is substantially free of surfactant and comprises an acrylic or methacrylic polymer or copolymer, an inorganic filler and a white pigment; and a releasable material (layer D), wherein the releasable material comprises amorphous nanoscale silica and a polymeric binder. The waterproofing membrane does not require a release liner, binds strongly to concrete cast against it (even after UV exposure), tolerates foot traffic, and withstands immersion in water over an extended period.
