Are your 1/4" 4' x 10' Tough Mats thick enough for use under a squat rack station? Heavy weights may be dropped. This is in a basement that has carpet laid over concrete.

Our Tough Mats are thick enough to be used as flooring under a squat rack station. When installing these rubber mats over carpet, they work best over commercial-grade carpet. If installing over a high pile, thick padded carpet, we would recommend installing a 1/4" plywood board over the carpet or to go with one of our thicker mats.
