Soooo, I have had an extension built which is watertight and fully roofed. I am doing the majority of the remaing work. The ground floor is a suspended floor with 8x2 joists at 400 centres. The largest span is approximately 2.5 metres with sleeper walls and internal walls breaking up the spans across the entire 6 metre width of the building.
I am planning to ultimately tile the ground floor throughout with tiles that are 300x300mm. The floor substrate is currently 22mm Caberfloor P5, glued and screwed. I am yet to do a deflection test, but I suspect it will be at least relatively minor, but I am looking for the minimum of L/360. The biggest room is the kitchen, so a relatively high traffic area (and a hallway).
I am aware that of the need for rigidity and to that end, I am proposing to use Hardiebacker board of at least 6mm thickness, possibly 12mm to attain a suitable surface to tile onto and to create a further layer of rigidity. I do need to consider the flooring heights in relation to the existing floor heights.
Does this sound like a reasonable and workable approach?
TIA
