An anti-fracture, water-resistant, masonry-bondable membrane comprises a lamina having a central layer generally containing at least one ply of a flexible material, e. g. , an organic polymer such as polyvinyl chloride, generally in the form of a sheet, and a nonwoven fiber layer physically bonded to each side thereof. The formation of the lamina is generally accomplished by laminating a single, nonwoven layer to a layer or sheet of a flexible material in the presence of heat and pressure to produce a construction wherein the nonwoven fibers are partially embedded in the flexible material. Subsequently, two such constructions are bonded together under heat and pressure to produce essentially a four-ply lamina wherein the layers of flexible material such as a polymer are fused to one another. The flexible membrane lamina, when utilized between and bonded to an exterior masonry article such as ceramic tile and to a substrate such as concrete, is very effective in preventing any cracks from propagating from the substrate to the article. The flexible membrane also has very good hydrostatic water resistance.

An anti-fracture, water-resistant, masonry-bondable membrane comprises a laminate having a core generally containing at least two plies of a flexible material bonded together by a flexible adhesive such as a plastisol, and a non-woven fiber layer physically bonded directly to at least one side of the core. The plastisol is a liquid composition which contains small sized resin particles such as polyvinyl chloride dispersed within a plasticizer. The core has good low as well as high temperature peel strength. The non-woven fiber layer is physically bonded to the flexible core by heat and pressure to produce a laminate wherein the non-woven fibers are partially embedded within the flexible material. The flexible membrane or laminate when utilized between and bonded to an exterior masonry article such as ceramic tile and to a substrate such as concrete, is very effective in preventing any cracks from propagating from the substrate to the article.
