Our underlays offer exceptionally high performance and provide a highly protective barrier between substrate and liner. We recommend that our heavy duty underlay is used beneath all of our liners, not only to help protect the liners from penetration by sharp stones, roots etc, but also to reduce excessive localised stretching of the liner when ground settlement occurs over time.
