Brick house stands on a concrete slab, then 40 cm of sand – EPS 10 cm-monolithic floor. Need to level this floor with differences max 10 cm on 140 square meters of the first floor.
Most of it without a warm floor, part of the wiring pipes with a coolant in special mats with a heater already. Two types of coating – porcelain tiles, where the pipes and parquet / board where there is no floor heating. The floor is also laid on the heating pipes in the insulation.
I think that the right thing to pour concrete m300 with a small fraction of crushed stone, but do I need to put insulation in general? Do I need a primer? Do I need a grid?
