TANK GOODNESS FOR CHANGING TILE
REGULATIONS
Ann Boardman, head of marketing and product development at Saniflo UK, tells BMJ how builders’ merchants can keep things simple in light of the change of regulations for tiling in wet areas.
T
he British Standards Institute (BSI) codes of practice for BS 5385-1 stipulates that all substrates should be waterproofed before tiling, even in domestic locations. Clause 6.1.1.3 states: “In wet areas … substrates should be protected with a suitable proprietary tanking membrane system.”
At Saniflo, we offer an easy solution. The range of Kinedo cubicles from Saniflo is unaffected by the regulation because of the integrated glass panels that form a leak free showering interior. The clever assembly of the internal glass panels, over the upstands of the Kinedo shower tray, ensures the unit is waterproof without the need to tile, grout or use silicone or a tanking system. Locating systems for the glass panels further ensure water is routed to the inside edge of the tray and towards the waste outlet. As a result of these new regulations the installation of a Kinedo cubicle will save customers even more time and money.
For customers that are affected by BS5385-1 the definition of ‘wet area’ includes bathrooms, wet rooms, shower spaces, steam rooms and any other location subject to frequent water contact. Substrates include plasterboard, plaster and backer boards which are often moisture sensitive. These areas are generally tiled; however tiles are not enough to stop the penetration of water, particularly given that adhesive and grouts are porous enabling moisture to pass through. Over time water can be absorbed via the grout joints and adhesive bed surfaces - potentially damaging the underlying substrate and causing damp and mould issues which can be unsightly, costly to fix and unhealthy.
The change is designed to improve standards 38

for customers, which is great news. There is clearly a cost implication though – increased labour and material costs plus, undoubtedly, an impact on the duration of the project. Longer term, the installation of tanking will minimise call outs for leaks.
Sometimes it is the enclosure that gets the bad press when it is actually the lack of a membrane that causes water damage. At Saniflo we certainly welcome the changes for our enclosure clients. Our cubicle customers should be aware of the new regulations but they do not need to change their methods of installation because of the unique design of the Kinedo cubicle. BMJ
