What is Gordon Low Heavy Duty Underlay?

Gordon Low Heavy Duty Underlay is designed to be laid underneath laid under suitable pond liner and prevents sharp stones and roots from puncturing your pond liner. Underlays are made from a variety of materials but this underlay is fashioned from 250gsm-thick geotextile felt which is heavy-duty.

What are Gordon Low underlays made from?

Gordon Low underlays are made from high-quality materials that are sourced from leading European manufacturers, which makes their underlay superior and ideal for quality pond building. Mechanically bonded and needle-punched, these geotextile underlays are effective for use with pond liners.

What is geotextile underlay?

Geotextile pond liner underlays are permeable materials that come in three forms: superior non-woven, needle punched or heat bonded. They have the ability to protect and drain and act as a protective layer. These geotextile underlays offer exceptionally high performance and provide a highly effective protective barrier between substrate and pond liner.

What are the benefits of underlays?

We always recommend using a high-quality underlay with all pond liners. Not only does the underlay help protect the pond liner from sharp stones and roots, but also reduces excessive localised stretching of the pond liner which can be caused when ground settlement occurs over a period of time.

What underlay do I need for my pond?

This pond underlay is supplied by the running metre 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. Our handy Pond Liner Calculator lets you find the correct size of your pond. We match the size of your liner to an appropriate pond liner underlay, so these will generally be the same size.

Please note: Every 10 requested widths will be supplied in 10 x 2m strips.
