mixed substrate floor

Kerdi or dural wp.. or pci pecilastic , all are crack isolators as well.

I use the kerdi one not the cheapest but has always worked

So if I was to use Kerdi matting as a crack isolator do I cover the whole floor, or just over the ply overlapping onto the concrete?

cheers for the advice

I would use it to just bridge over the ply over the pipes and onto the screeded area, not the whole floor.

Sounds like a cunning plan to me.
Think I'll go for the Kerdi option.

Cheers for that
