Introduction to Wet Room Membrane

A wet room membrane is a crucial component in modern bathroom and wet area construction. It is a waterproof barrier that prevents water from seeping into the underlying structures, such as floors and walls. This not only protects the building from water damage, including rot, mold growth, and structural deterioration but also extends the lifespan of the wet room. Wet room membranes are typically made from various materials like PVC, rubber, and bitumen, and they come in different forms, such as sheets and liquid - applied membranes. They are easy to install and can conform to different shapes and sizes, making them suitable for a wide range of wet room designs.
