Well just been to site to find the builder pulling his hair out, a clueless customer, and a what looks like half a spec from the wet system manufacturers.
Told the customer to consider an undertile electric system, as the wet system wasnt going to work.
Not what he wanted to hear, but understands the consequences of the floor failing.
Will wait to hear the outcome, and let you guys know.

The joists are 10mm apart so its ok

Hello CR,
I was told earlier today, its UFH system laid in plastic trays, with an unspecified joist width, with a builder that was insisting it had a maximum of a 12mm ply over the top.
The tile to be laid is 825x550x20 limestone tile from Mandarin stone. Obviously I was keen to know who would specify 12mm ply as a substrate.
I was introduced to Nicobonds "Plastic Ply", http://www.nicobond.com/files/Information_Sheet.pdf and wondered if a solution could be found combining these products.
After going to the site this evening, the wet system is the problem, and trying to skimp on floor height with substrate isnt the answer.
The builder was still on site after 6.30pm, very irate after trying to remove enough screed to accomodate a wet UFh system over 56 metres of floor.
In places, the floor has lost over 200mm of screed! When I asked why and electric syem wasnt installed, the customer said it was expensive to run.
I told them that the electric system should be used, and wished the builder good luck re screeding the floor.
I left it in the customers hands and await a reply.

These systems are spec'd like this by a couple of manufacturers and suggest the thermal boards are loose laid or screwed, then after the pipes are inserted two layers of cross bonded 6mm ply are loose laid on top then tiled with flexible adhesive.
No no no!!! What an awful system.
I've encountered a few and the only way i would tile them is to fix the thermal boards down with adhesive and screws. Lay the pipes then Level over the whole system, then Ditra over the whole floor. Then fix the tiles.
Any less than that is seriously asking for trouble Fraser.

wow, thats different, didn't even consider that as an option, have you tried it before?
What depth of bed of flexible leveling did you use, what kind of adhesive, SPf or 2 part?
My concerns are the strength in the floor and weight being taken on the plastic pipe trays

So you didn't mean a suspended floor as per your first post. You meant a floating floor?
