My new concrete floor in the extension went down pretty well. In fact couldn’t have hoped for better as a first attempt. It’s 12mm lower than the old floor it adjoins. Done on purpose to allow a bit of tolerance if it all went tits up so SLC could rectify. Could have done it higher in hindsight but that’s the way it is. Just more SLC to add now.
My problem is the old kitchen floor. Removed old 80’s tiles and adhesive to reveal the original square 1.5” thick quarry tiles. The levels are all over the place. Dips in the middle, raised at the edges. Not evenly either. Can be 20mm out in places. Most annoyingly it kicks up at the join between old and new.
The photo shows the rough lie of the land and the green lines show the boundary to the breakfast room which is surprisingly flat and level.
I don’t think I can just wack tonnes of SLC down to fix the lot due to immense cost and it will then screw up the levels into the breakfast room.
Wondering if it’s worth just taking up the quarries and screeding the old floor then SLC the new floor to this? Feels like something I’d rather avoid. Thought groundworks were over.
As you can imagine, I very much doubt a DPM is under these quarries. Should I bang one down if digging up?
