We searched high and low for the right material to replace our old underlay and this is it! We've taken a product that is used under reservoirs and adapted it for use in the garden pond. Incredibly strong, easy to lay and made to last a lifetime, Permalay will protect your liner for years to come.
Our underlay will arrive in multiple peices ready for you to cut and overlap yourself to fit into your pond. Simply select the same size as your pond liner and we'll make sure you receive enough to cover the area!
