This bundle pairs a 3 m × 3 m (approx. 9.8 ft × 9.8 ft) L-Grade 200 gsm pond liner with a 50 gsm anti-weed fabric underlay for complete protection and peace of mind. The deep black UV-stable liner provides a striking, natural water backdrop, while the grey underside stays neatly out of sight beneath the surface. The included underlay prevents weed ingress and cushions the liner against sharp stones or debris below.

Constructed from high-strength polyethylene at 200 gsm, this liner delivers exceptional tear, puncture and abrasion resistance across its entire area, yet remains pliable enough to mould around curves, planting shelves and varying depths without seams. With built-in UV and chemical stability, your water feature will remain leak-free and visually vibrant for years to come.

  • Size: 3 m × 3 m (approx. 9.8 ft × 9.8 ft)
  • Liner material: UV-stable, high-strength polyethylene

All products, unless otherwise stated, come with a standard manufacturer warranty against faulty workmanship.

If your product fails within six months of delivery, please contact us with your order reference number, a description of the issue, and clear images illustrating the fault.

Should your item require a return for further investigation, it is your responsibility to arrange and cover postage back to us.

If we are unable to repair the fault, we may offer either a replacement or a full refund.

In cases where the item is inspected and found not to be faulty—or where damage is determined not to be due to manufacturing defects—you will not be entitled to a refund or replacement. We will then either return the item to you via standard post or dispose of it at your request.

Please see our warranty policy for further information.

You may return any order within 14 days of delivery. As soon as you receive your items, please inspect them carefully—taking reasonable care to keep both the product and its packaging clean and undamaged. If you discover an error or defect after 14 days, we reserve the right to decline your return. If your product fails or breaks after this 14-day time window then your order may be eligible for a warranty claim, please see our warranty information for more details.

To initiate a return, please contact us via our contact form to obtain a return authorisation and the correct returns address (different from the address on your invoice). This can also be done through your 'recent orders' page on your account if you are registered with Shop. Returns sent without prior authorisation will be discarded.

Returned items must be in the same condition in which you received them—unworn or unused, with tags attached and in their original packaging. You must include either a copy of your invoice or a slip with your order reference number inside the parcel. Please be sure not to obscure your return reference number on the label.

If you refuse delivery or reject the parcel without prior notice, we will inspect the returned package and issue a refund upon receipt. Although there is no restocking fee, we will deduct the cost of the return postage label (£3.35) from your refund.

If the returned item or its packaging shows signs of use, damage, or staining, we may deduct up to 50% of the order value—or refuse the return entirely—depending on its condition. Examples include damaged tags, stained, modified or damaged packaging, or missing components.

For faulty, incorrect, or damaged items, please contact us before sending anything back so we can attempt to resolve the issue directly. If we agree that a return is necessary due to our error, we will provide you with a pre-paid return label.

Products that have been modified or damaged through customer action are not eligible for return. This includes, but is not limited to, items that have been cut, trimmed or otherwise altered—such as a tarpaulin or pond liner resized to your specifications—or any product showing damage beyond normal inspection handling.
