We do not usually recommend PVC backed coir for outdoor use. In situations where it is likely to get very wet, the PVC backing prevents the water running away. Normal indoor use where the mat becomes wet from shoes and umbrellas etc is absolutely fine, and is what this matting is designed for, but we do not recommend it being left outside to the elements. If you do wish to use PVC backed coir in an outdoor location the backing can be punctured with holes to allow any water build up to run away.
