But you still didn’t tell us to what height the tile safe should be installed.............

So given bathroom floors average shall we say 4m2 your 5m2 kit is no where near big enough to tank a wet room walls as well (provided below 20kg/m2) following your recommendation and so a 10m2 kit would be needed........... yes ?

So another tanking system would be needed if using 20+kg/m2 load

On a wood floor or new screeds for example how would tile safe prevent cracking of tiled areas due to lateral expansion and contraction of the sub floor as would Durabase CI, Ditra ?

This is sufficient for the Tile safe application. For the tanking of wet room walls we recommend you use an alternative liquid or fleece tanking system or a waterproof backer board.

If tilesafe is recommended for floors and you don’t supply pre-made flexible internal/external corners and tapes surely a purchaser would be better off buying a complete system such as Durabase WP tanking where everything can work hand in hand (with one source of customer backup) rather than having two differing methods of tanking in one room ...?

There is no need to apply a self levelling compound to 'protect' the membrane from going soft (as it's a rubberised bitumen based sheet).

I understand a self leveling compound is used primarily to protect the cable and create a good working surface not to protect a membrane.

So you advocate tiling over your aqua dec base with UFH despite the fact that building of layers over a former could alter fall patterns and inhibit water drainage. Should this happen and the base need lifting you will lose the UFH for the whole room wont you ?
