I have a dilemma involving laying carpet over asbestos tile. My current carpet is glued to the tile. In order to avoid asbestos abatement, I must install new carpet over the old using the old as padding. My problem is securing the carpet around the edges as I cannot fasten tack strip to the floor because I am not allowed to drill or nail through the asbestos tile. Is there a way to secure some kind of metal tack strip to the walls and then cover with molding?
