A roof/wall structure includes a substantially rigid substrate and a waterproof membrane adhesively joined to an outer surface of the substrate. The membrane includes a layer of thermoplastic or elastomeric waterproof material, a layer of cushion material bound to an inner surface of the layer of waterproof material, and a pressure sensitive adhesive bound to a side of the layer of cushion material remote from the layer of waterproof material and bound to the substrate.

1. A method for waterproofing a structural surface, the method comprising the steps of: providing a waterproof composite membrane for adhesive application to an outer surface of the structural surface to substantially cover the surface, the composite membrane comprising;an outer surface layer of a selected one of thermoplastic and elastomeric waterproof material of about 60 mils thickness or greater;a backing layer of homogeneous non-absorptive closed-cell foam material of about 60 mils thickness or greater and constant cross-section bonded in continuous contact with an inner surface of said layer of thermoplastic or elastomeric material;the layer of foam material and the outer surface layer being bound to each other surface-to-surface so as to be devoid of a medium for lateral migration of water therethrough;a pressure sensitive adhesive contiguous with and bound to a side of said foam material remote from the outer surface layer;the layer of foam material being adapted to conform around irregularities in the structural surface;a release liner removably mounted on the pressure sensitive adhesive remote from the layer of foam material; anda 2-4 inch selvedge structure for overlapping and bonding of said waterproof material to an adjoining membrane;removing the release liner to expose the pressure sensitive adhesive;pressing the pressure sensitive adhesive against the structural surface; andoverlapping the selvedge structure unto an adjoining membrane to conform the layer of foam material to the structural surface and bond the waterproof membrane to the structural surface;wherein the composite membrane provides waterproofing and moisture protection. 2. The method in accordance with claim 1, wherein the outer surface layer of thermoplastic or elastomeric material comprises at least in part a selected one of vinyl and polyolefin. 3. The method in accordance with claim 2, wherein the outer surface layer of thermoplastic or elastomeric material further comprises reinforcing comprising one of glass fiber and polyester. 4. The method in accordance with claim 1, wherein the outer surface layer is heat sealed to the layer of foam material. 5. The method in accordance with claim 1, wherein the waterproof membrane extends 2-4 inches on a side thereof beyond a side edge of adjoining foam material to form the selvedge structure; and comprising the further step of bonding the selvedge structure to a top edge portion of an abutting layer of waterproof material of a second waterproof membrane. 6. The method in accordance with claim 1, wherein the assembly comprising the layer of material, the waterproof material, the layer of pressure sensitive adhesive, the release liner, and the selvedge is assembled in rolls of about 6.5-12.0 feet in width with the selvedge extending a further 2-4 inches widthwise, a selected number of the rolls being transportable to a construction site and placed on a structure, the rolls being thereafter unrolled side-by-side, the release liner being removed from the adhesive, and strips of the assembly being laid down side-by-side with the selvedge of one strip overlaying an adjacent edge of a second strip. 7. The method in accordance with claim 1, wherein said pressure sensitive adhesive layer is provided with adhesive properties which remain in the presence of water and concrete alkalis. 8. The method in accordance with claim 1, wherein said release liner is manually removed from said pressure sensitive adhesive. 9. The method in accordance with claim 1, wherein said outer surface layer comprises at least in part a selected one of vinyl and polyolefin. 10. The membrane in accordance with claim 1, wherein said outer surface layer is bound to said layer of foam material by a selected one of adhesive adhering, laminating, extrusion coating, heat sealing, gluing, and taping. 11. The membrane in accordance with claim 1, wherein said pressure sensitive adhesive layer is manually attached to the surface of the structure by placement of the adhesive layer on the surface of the structure. 12. The membrane in accordance with claim 8, wherein said outer surface layer further comprises integral reinforcing material. 13. The membrane in accordance with claim 12, wherein said integral reinforcing material comprises a selected one of glass fiber, polyester, and nylon. 14. The membrane in accordance with claim 1, wherein said layer of foam material retains conforming properties in the presence of water and alkalis, and prevents lateral water migration. 15. The method in accordance with claim 1, wherein the outer surface layer is heat sealed to the layer of foam material.
