We recently knocked down a wall between kitchen and dinning room. The floors either side of where the wall are not flush to each other all the way across where the wall has been. On one end they are flush, but on the other end, there is about a 30 mm height difference between floors (see floor plan). This might be due to subsidence, not sure. From one wall where they are flush, all the way across to the other end, where it isn't, the ramp increase is gradual, almost like if you were to twist a long rectangular plank, no sudden changes in the ramp. We plan to lay some laminate flooring in both rooms but are a bit unsure about how to tackle this issue. Using a threshold would not work because the ramp is not uniform across, wall to wall.
This happens all the time. You can either screed the ramp out or you have to break the high spot out and re do it
I'm not sure what that means. When you say screed the ramp out, do you mean pour levelling compound in the dining room to the height of the ramp?
I think I 'll need more detail so i understand what you mean. I'm not a builder so my understanding is that you pour screed in the dining room so it levels out the dining room and make it flush with the kitchen? The floors in both the dining room and kitchen are marley tiles and may contain asbestos. I suspect I would need to break up the tiles to create a surface that the slc can bond to as I don't think it would bond to marley tiles as well. Would this be the only option?
If they are solid ardex na will stick to them. But best advice is take all the tiles up and get a pro in to prepare the sub floor for you.
