Here's my problem. House built in 1939. Basement is semi-finished with floor covered with cracking/peeling vinyl asbestos tiles. There are several areas of the concrete that bulge upward, approximately 1/2 inch higher than the rest of the floor, making the floor uneven. I have approximately 7 feet of clearance from the floor to the ceiling. I have a few ideas. Does anyone have any suggestions?
1. Forget about the vinyl asbestos tile and install a subfloor (like the dricore interlocking system) using their spacers to make up the difference in floor heights. Or is 1/2 inch too much to make up with spacers? 2. Scrape up the vinyl asbestos tile, use a leveling compound to level the floor (anyone have a suggestion about what kind of company does this kind of leveling?), then install sleepers and a subfloor. 3. Scrape up the vinyl asbestos tile and hack out the areas of raised/heaved concrete with a sledge hammer and chisel, then fill in these areas with a concrete patching compound.
By the way, does anyone know if vinyl asbestos tiles are dangerous to deal with. I've read that because the asbestos is in the vinyl it's not dangerous. Any help would be appreciated. Thanks
