Hi,
Builder has poured two separate concrete floors either side of a wall, the wall has now come down as going to be open plan area, and turns out floors are at different levels.
The next step was going to be insulation board and then pipework on top for under floor heating and a liquid screed poured on top and then the long wait before porcelain tiles to finish.
So today there was discussion on how to get floors to same level before putting the insulation board on top, the solution they came up with was to use sand they had on site to bring the lower floor up, don't think there is much difference in levels - about 20mm.
Is this an acceptable/regular solution ? The kitchen with island is going on top of what is the lower floor raised with sand, guess will be quite compacted but concerned about movement or compression of floor over time. Area is about 4m by 4.5m.
Any thoughts greatly appreciated,
Lawrence
