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.


This sheet is supplied with a width of 2m, with pricing determined by the length desired and cut to order. Just enter the required length in metres as the item quantity. For example, should you require 2m x 5m, enter a quantity of 5.


Please ensure you have entered the correct length required (in metres) as no refunds may be made in the event that you order the incorrect length and the liner has been cut.
