What to look for
Carpet underlay containing asbestos is likely to be brown and look like a fibrous mat. It’s likely to be compacted under the carpet as it was often glued to concrete floors or stapled to timber floors.
Non-Friable asbestos was also added to the glue used on carpet underlay. It usually looks like a black bituminous dried adhesive.
