I have a hall floor that has sunken in areas.
It appears that the original floor was filled with building rubble, topped with sand and the a quarry tile on top.
I am looking to remove the top layer and replace with concrete. Whilst at it I might as well consider putting in a insulated floor.
How should a new floor be put in, what dpc/insulation should be used. What thickness of concrete needs to be put in over the current substrate material.
