When we pulled back the carpet and padding we discovered an odd floor covering that looks like nothing I've seen before.
The covering is about 1/8 inch thick and the underside is similar to tar paper. The covering is very brittle and is coming up rather easily, but we want to make sure there's nothing hazardous here. I have no idea as to how long this covering has been down on the floor, but I would guess, from paint stains and the age of the carpet that it is more than 20 years old.
Any thoughts on what this might be? Thanks in advance for any thoughts.
