Tanking

[Flintstone]

i will go check with the TM bods, but i would advise that tanking is the last thing to be done.....

Any joy with this question ?

Afternoon All,

In reality, there is no right or wrong way with regards to where in the process of building up the layers a tanking solution can be applied. We would normally advise to tank first, being that the substrates are tanked prior to a tiling installation being installed over the top.

That is not to say however, that tanking above the UFH and self levelling compound and directly underneath the tile is an incorrect tanking method. Essentially the room is tanked and ready to accept the demands that will be put upon it.

I'm sure that in the vast majority of circumstances, the UFH would be being applied to a tilebacker board (such as Delta, Wedi, Jackon, Marmox etc) that are themselves a form of tanking once the joints have been taped/tanked, so in this instance, the UFH and self levelling compound would be being applied to the surface.

With regards to an uncoupling membrane/mat, this should always be applied as close to the tiled surface as possible. If an uncoupling membrane is being installed as a dual uncoupling/tanking system, then we would advise this is installed as close to the tiled surface as is possible for the uncoupling aspect to work fully.
