The invention discloses a waterproof membrane comprising a carrier sheet (layer A); a waterproof adhesive (layer B); a protective coating (layer C), wherein the protective coating is substantially free of surfactant and comprises acrylic or a methacrylic polymer or copolymer, an inorganic filler and a white pigment; and a releaseable material (layer D), wherein the releasable material comprises amorphous nano-sized vermiculite and a polymeric binder. This waterproof membrane does not require a release liner and is strongly adhered to the concrete it is poured against (even after exposure to UV), tolerant to walk and to withstand extended periods of flooding. |
