BU518 Wet area tile waterproofing (2009)
Product Description
A tiled surface with cement-based grouted joints is not inherently waterproof, so any wet area tiling must be detailed and constructed to prevent moisture getting into and behind the substrate. Failure is not immediately obvious, and therefore damage to framing and substrates can be substantial.
Particular care in detailing and installation is required to overcome commonly identified problem areas.
