Hi,
I am working on replacing the old tiled floors in my mums house with a new concrete one. Having tried to research what I need to do in order to ensure the new floor is safe and also complies with building regs, I have come up with a sort of specification which I was hoping the experts around here would cast an eye over and let me know if its ok, or make suggestions on things I have got wrong.
OK, so the plan is to do the following:
Layers in order from the top down.
Concrete - 100mm
500guage polythene
Celotex GA4090 insulation board - 90mm
DPM lapped into walls.
sand blinder - 50mm
Well compacted aggregate - 100mm
I will also be putting celotex TB4020 boards around the edge of the slab to insulate the edge.
Like I said, any suggestions/advice verfy much welcomed!
