question about mesh v's ditra

[Rina Rowe]

We are doing an extension to our home and planned to tile the whole ground floor. We are using large 80 x80 porcelain tiles. On our spec, it specifies for the builder to use ditra mat under tiles. We have floorboards covered with OSB. The builder has now started tiling using reinforcement fibreglass mesh Reinforcement fibreglass mesh for waterproofing under tiling on terraces, waterproof under tiling on bathroom walls and floors - Reinforcement mesh - http://www.arcane-industries.co.uk/p246_r2676-reinforcement-fibreglass-mesh-for-waterproofing-under-tiling-on-terraces-waterproof-under-tiling-on-bathroom-walls-and-floors.html. He has promised us that it is just as good, if not even better than ditra mat. I have no idea whether to believe him or not as its cheaper and easier to lay the mesh. Can anyone please advise.??
Thanks so much

Ditra is an uncoulping membrane, what he is using is not.
if the spec says us ditra why let him use something else? and why is a builder doing tiling?
looks like his trying to save himself a few pounds.

Welcome to the forum 🙂 personally would never dream of tiling onto osb boards especially not on floors! Also had a look at mesh thing he is using and would not go near it! Ditra mat is the way to go, and osb boards up and tile insulation or tile backer boards down first glued and screwed

In America they put ditra over osb, over here tho it is not common practice. As said, the mesh is no good, better to get that and the osb up before it gets too far, what sort of area has he stuck down ? Is he a tiler that the builder has got in or is it the builder himself doing the tiling ?

Here in italy, terraces are all done so.
The expense is the same, more or less.
It costs less the product it is using but needs more labor.
The mesh on the walls is never laid, the bandles are enough.

sorry
But is he doing it on the panels inside the house?

Let me get this straight you are saying they use Osb not wpb ply in America to tile on ?
