  • Build your garden pond: a 6m × 6m nominal sheet of flexible 200gsm PE for the water-holding layer.

  • Black face with grey reverse: UV-resistant PE for outdoor ponds and garden water features.
  • Choose your own underlay: suitable protection is required beneath the liner and is sold separately.
  • One liner supplied: cut-size tolerance ±5%. Allow for depth and edging; prepare smooth ground and remove sharp debris before fitting.

Description

A square PE sheet for a pond shaped around your garden

This nominal 6m × 6m pond liner supplies 36m² of flat 200gsm polyethylene. Its flexible sheet can follow a prepared excavation, including curved sides and planting shelves, rather than a rigid preformed outline. The black face and grey reverse give the liner its two-colour finish.

Underlay is required beneath the liner and is sold separately.

Start with the ground and the underlay

Plan suitable protection beneath the sheet before fitting it. The fabric underlay options shown above are sold separately and need their coverage and overlaps arranged for your excavation.

Clear the pond surfaces

Remove sharp stones, roots and debris from the base, sides and shelves. Smooth the supporting ground before placing underlay.

Arrange the protective layer

Check sufficient coverage and any overlaps around the contours. Choose protection appropriate to the actual ground conditions.

Settle the flexible liner

Ease the sheet into the excavation without tension across gaps. Keep material available for the perimeter and check the position before filling.

Check both routes through the excavation

Equal sheet dimensions do not mean the finished pond must be square. A curved or irregular outline can fit, provided the complete routes through the pond use no more material than the sheet allows.

Measure the longest and widest paths along the actual contours, including depth, side walls and shelves. Add the allowance for your edge finish, then compare both measurements with the nominal 6m sides. Allow for the ±5% cut-size tolerance. The 36m² figure describes flat material, not finished water-surface area.

What is supplied with this liner?

One nominal 6m × 6m 200gsm PE pond liner, with a black face, grey reverse and UV resistance for outdoor pond use. Underlay, edging, plants, stones and installation accessories are not included.

GSM describes the liner's weight per square metre rather than thickness. This sheet is polyethylene, not EPDM rubber. Ordering more than one supplies separate liners, not one larger sheet.

Choosing the 6m × 6m liner

Is underlay supplied with this product?

No. This is the liner-only product. Underlay is required and sold separately. Plan its coverage, overlaps and protection for the actual excavation and ground conditions.

Can a square sheet follow an irregular pond shape?

Yes, if both full routes through the prepared excavation fit within the sheet. Include the material needed for depth, sides, shelves and the perimeter finish, with the ±5% cut-size tolerance accounted for.

Does it provide 36m² of water surface?

No. The nominal 36m² is the area of the liner laid flat. Material used for the sides, depth and edges is part of that same sheet.
