Whats best for travertine

[groucho]

Been reading a few posts and spoke to a few tile experts but its not clear whats best for fixing travertine. I mean if its timber flooring I would put backer boards down but then someone said its got to be ditramatting. Im aware that ditra offers little in the way of support for deflection etc but the guy was quite sure it was best for that type of tile. would you use ditra on a screeded floor or just straight down with the tiles as normal ? Thanks

If its a new floor then 100% uncoupling membrane, if its an established stable screed then it's your choice

IMO with stone tiles " every time "




An uncoupling membrane whether Ditra or Durabase will save stress on the tiles from latteral deflection / movement eg when a screed / floor expands and contracts across its surface. A new floor or one with with wet under floor heating must use a membrane.

Unlike mam made tiles stone especialy Travertine will not crack along the grout joints but will tear along the fault beneath........
