ABSTRACT:
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.
