Liquid vs. Sheet Waterproofing Membranes
Choose the right membrane for your project. Liquid-applied membranes, like Mapei Mapelastic AquaDefense, create a seamless, flexible layer that conforms to corners and penetrations. Sheet-applied membranes, such as Schluter KERDI, ensure uniform thickness, immediate tiling, and long-term durability.
Dual-Function Membranes: Uncoupling + Waterproofing
Products like Schluter DITRA combine waterproofing with an uncoupling layer, preventing floor cracks from transferring through the tile assembly. Ideal for large-format tiles, heated floors, or concrete subfloors.
