Swell's Heavy Duty Underlay is made from high quality materials which makes the underlay superior, it offers exceptionally high performance and provides a highly effective protective barrier between substrate and liner. The Geo-textile fabric is designed specifically for use with pond liners.
At Swell UK, we always recommend using a high quality underlay with all pond liners. Not only does the underlay help protect the liner from sharp stones, roots etc., but will also help to reduce excessive stretching of the liner which could be caused from the ground settling over a period of time.
The 80g per square metre underlay is a superb quality and is unaffected by extreme climate influences such as frost, heat or moisture.
The underlay is supplied in 2 metre widths so when placing your order all you will need to do is enter the quantity you require. For example, if you are purchasing a 10 x 5m pond liner the quantity you would enter in the underlay amount would be 25. To work this out you simply do 10 x 5 = 50 / 2 = 25.
At Swell UK we sell pond liners and underlay as individual items, but we also stock a range of Pond Liners and Underlay combinations. If you cannot find what you are looking for please call the sales team on 0161 351 4700 who will be more than happy to help.
