Guys,
Ripping up my old concrete floor (1950's house has no insulation) to install a new concrete base, insulation & screed including wet underfloor heating.
I will be ripping down initially 75mm for screed, 100mm insulation and 100mm for concrete base.
Question is how much depth should I allow for the sand/dpm/hardcore base? The floor is approx 17m2.
Thanks
