Hi, After removing ceramic floor tiles, I found two damp patches on the tile adhesive left on the floor, this was caused by the mastic asphalt being damaged and the tiler filling the holes with his adhesive.
I have cut the asphalt back and removed the top layer of sand and cement screed that was about 2” thick. The cavity was filed with a mixture of sand, bits of copper pipe, plastic pipe clips, nails, rotten wood, and broken bit s of brick.
The DPM has been cut off at the base of the slab (don’t know why this has been done) and it looks like the slab is sitting on a course of bricks but can’t be sure, theirs also no DPC under the UPVC door
What is the best way to fix this as I want to lay LVC or laminate flooring.
Any help is appreciated.
