Identifying Asbestos Floor Tiles
Posted May 13 2010 - 11:35 AM
I've got about 15-20 9x9 floor tiles covered by a small area rug in my basement. I didn't put them down and don't know the make/model of them. I'm concerned is b/c the kids toys are relatively close to the tiles. I can post a picture tonight if necessary.
Thanks in advance!!

Generally I don't even sample 9x9 floor tiles. I always assume them to be asbestos-containing. Due to the matrix of the tile they can be prone to false negatives unless you opt for more expensive tests and I have never had one come back as non-ACM. The mastic beneath them is also a suspect ACM. I would treat both materials as ACM.
As far as toys coming into contact, so long as the tiles aren't chipping, cracking, or generating dust there is no risk of exposure. The percentage of the tile which is actually asbestos is probably 2-5 percent. Breakage or sanding would create dust but even then risk of exposure is unlikely. If you ever do see broken pieces clean them up immediately.

If you are concerned about the tiles, you can lay new 12" x 12" tiles over the existing 9" x 9" tiles. If you are really concerned about the tiles, you can wet the existing 9" x 9" tiles with water and they should pop up with a hand scraper, then replace the area with 12" x 12' tiles. Place the tiles in a small box and then in a plastic bag and throw away.

Unfortunately, I don't. The house is almost 100 years old
Thank you for your post CJ, Junkfish and Irwin 1951!!! Recently, some of the tiles have cracked/chipped and I my wife covered them up with the rug.
For piece of mind, I'll probably wet the tiles and remove them one by one. Thanks again guys!
