Will these work on a basement floor under marley for a dance floor?
Our 5/8" Diamond Soft Tiles are not a high-dense foam, so we wouldn't recommend using them under marley flooring as a subfloor for practicing dance. We do have two foam tiles that would work perfectly for this purpose. They are our 3/8" HD Soft Tiles and our 3/4" Premium HD Soft Tiles. You can find these as subfloor options on our dance flooring list page.
