For over 40 years, XR-5 has been used by engineers who have needed the strongest geomembrane for use in the world’s harshest conditions. XR-5 is the highest-strength and most chemically-resistant geomembrane on the market. It was developed to contain and protect against acids, oils, methane, and alkalis.
