When the British Standards Institute issued codes of practice for BS 5385-1 for internal wall and floor tiling, it changed regulations for tiling wet areas.
In a bid to properly waterproof homes – including bathrooms, showers, enclosures and anywhere else exposed to water contact – this new regulation aims to improve water and moisture resistance in these areas.
The regulation states that ‘tiling directly onto plywood is no longer recommended for wall tiling’.
Better waterproof alternatives?
As an alternative to plasterboard, XtraBacker tile backer board is one such waterproof solution. It’s a high-density, water-resistant backboard (with good thermal protection) used for tiles and natural stones. The XtraBacker prevents moisture build-up and mould growth, which are the most common causes of tile damage and failure in UK homes.
Aside from being an ideal waterproof alternative to dry lining materials like plasterboard, the XtraBacker is lightweight and strong. It’s trimmable to walls and floors, effectively covering areas with tiling.
Waterproofing wet areas
The most common areas in a house where water damage can affect tiling are the bathroom or kitchen. This is because these places are most likely to encounter water, or where moisture is expected to build up and damage tiling.
Water or moisture damage can quickly become expensive. It’s also a common failure in homes, where tiling against dry materials won’t necessarily prevent risky water build-up and damage over time. Tiles exposed to water can de-bond, form mould, rot, and fall apart without proper waterproofing.
If tiling could be part of your next job, consider these new regulations and how to properly and safely waterproof areas exposed to water.
