In addition to the “constant wet area” applications, a waterproofing membrane can also be used in “intermittent wet area” applications. For instance, the floor areas outside of a tub or shower are great candidates for waterproofing membrane treatments. In many cases, water spills or splashes out onto these areas and if left untreated, the water can migrate through the stone and grout and affect the substrate and the spaces below. Even minor water damage can prove to be very costly to repair.
It is also important to note that many of the waterproofing membranes available today also serve as anti-fracture membranes and help to reduce the potential for hairline shrinkage and “spider web cracks” from telegraphing through to the stone surface.
