Substrate Issues

[jfish]

I'm planning to use 22mm limestone on a multi layered substrate hallway; joists, ply between joists (fixed to batten), sellotex between joists, underfloor wet heating, screed over top between joists. Is ditramatt the best option with 22mm thick tiles?

make sure to leave a clean full depth joint around the perimeter of the floor, expansion joint
