Waterproof membranes

Abstract

Waterproof membranes have a single-ply polymer coated substrate and at least one adhesive layer for architectural and structural waterproofing.

What is claimed is: 
     
         1 . A waterproof membrane comprising:
 a waterproof barrier substrate having a base fabric of woven, knitted or non-woven polymeric or glass fibers;   a polymeric adhesive coating; and   a polymeric coating on both sides of the base fabric, and at least one additional adhesive applied to at least one side of the substrate.   
     
     
         2 . The waterproof membrane of  claim 1  wherein the base fabric of the waterproof barrier substrate is comprised of woven, knitted, or non-woven polyester or glass fiber fabric having a weight of approximately 6 to 10 ounces per square yard. 
     
     
         3 . The waterproof membrane of  claim 1  wherein the polymeric coating is comprised of a specially formulated compound that is highly compatible with additional adhesives. 
     
     
         4 . The waterproof membrane of  claim 1  further comprising one or more release covers adjacent to the at least one additional adhesive. 
     
     
         5 . The waterproof membrane of  claim 1  further comprising at least one additional layer of material on a top side of the waterproof membrane. 
     
     
         6 . The waterproof membrane of  claim 5  wherein the at least one additional layer of material on the top side of the waterproof membrane is an adhesive. 
     
     
         7 . The waterproof membrane of  claim 6  further comprising one or more release covers adjacent to the adhesive. 
     
     
         8 . A waterproof membrane comprising:
 a waterproof barrier substrate having a base fabric of woven, knitted or non-woven polymeric or glass fibers;   a polymeric adhesive coating; and   a polymeric coating on one side of the base fabric, and at least one additional adhesive applied to an un-coated side of the base fabric.   
     
     
         9 . The waterproof membrane of  claim 8  wherein the base fabric of the waterproof barrier substrate is comprised of woven, knitted, or non-woven polyester or glass fiber fabric having a weight of approximately 6 to 10 ounces per square yard. 
     
     
         10 . The waterproof membrane of  claim 8  wherein the base fabric of the waterproof barrier substrate is comprised of texturized polymeric yarns. 
     
     
         11 . The waterproof membrane of  claim 8  wherein the polymeric coating is comprised of a specially formulated compound that is highly compatible with additional adhesives. 
     
     
         12 . The waterproof membrane of  claim 8  further comprising one or more release covers adjacent to the at least one additional adhesive applied to an un-coated side of the base fabric. 
     
     
         13 . The waterproof membrane of  claim 8  further comprising at least one additional layer of material on a top side of the waterproof membrane. 
     
     
         14 . The waterproof membrane of  claim 13  wherein the at least one additional layer of material on the top side of the waterproof membrane is an adhesive. 
     
     
         15 . The waterproof membrane of  claim 14  further comprising one or more release covers adjacent to the adhesive. 
     
     
         16 . A single-ply waterproof and structural barrier substrate for a roofing membrane, comprising a polymeric adhesive and polymeric coating compound applied to at least one side of a base fabric, the base fabric having an uncoated underside for contact with an adhesive for bonding to a roof surface. 
     
     
         17 . The single ply waterproof and structural barrier substrate of  claim 16  in combination with an asphalt-containing adhesive and granules applied to a top side of the substrate. 
     
     
         18 . The single ply waterproof and structural barrier substrate of  claim 16  in combination with a non-woven polymeric fiber layer applied to the top side of the substrate and an asphalt-containing adhesive, and granules applied to the top side of the substrate. 
     
     
         19 . The single ply waterproof and structural barrier substrate of  claim 16  further comprising one or more release covers adjacent to the polymeric adhesive and polymeric coating compound. 
     
     
         20 . The single ply waterproof and structural barrier substrate of  claim 16  further comprising one or more release covers adjacent to the base fabric having an uncoated underside.
