  • Build your garden pond: a 5m × 5m nominal sheet of flexible 200gsm PE for the water-holding layer.
  • Follows your pond's contours: flexible polyethylene fits around curves, shelves and changes in depth without a rigid preformed shape.
  • 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 flexible square sheet for your garden pond

This nominal 5m × 5m pond liner gives you 25m² of flat polyethylene material to shape around a prepared excavation. Its flexible sheet can follow curves and planting shelves rather than defining a fixed pond outline.

The 200gsm PE liner has a black face and grey reverse, with UV resistance for outdoor pond use. Plan suitable underlay beneath it before installation.

One liner supplied. Underlay sold separately.

Measure the pond contours, not just its opening

The stated dimensions describe the liner laid flat. They include the material that will cover the pond base, depth, side walls and shelves, plus the allowance needed for the edge finish.

Measure the longest and widest routes along the actual excavation contours, then add the perimeter allowance. Compare both full measurements with the nominal 5m sides, allowing for the ±5% cut-size tolerance. The 25m² flat area is not a finished water-surface allowance.

Choose underlay for the ground beneath

Underlay is required with this liner and is not included. The separately sold fabric options shown above need their coverage and overlaps planned for your pond; assess the protection required by the actual ground conditions.

Clear and smooth

Remove sharp stones, roots and debris from the base, sides and shelves. Check the supporting surfaces before laying underlay.

Arrange the protective layer

Plan enough underlay coverage around the contours, including any overlaps. Do not assume one fabric sheet will fit the excavation.

Ease the liner into position

Follow the pond shape without stretching the PE tight across gaps. Leave sufficient at the edges and check the position before filling.

What arrives with the liner?

One nominal 5m × 5m 200gsm PE pond liner with a black face and grey reverse. Underlay, plants, stones, edging and installation accessories are not included.

The 200gsm rating is the liner's weight per square metre, not a thickness measurement. This is polyethylene rather than EPDM rubber. Ordering multiple quantities supplies separate liners, not one larger sheet.

Questions before you choose

Does this liner include underlay?

No. This listing supplies the liner only. Underlay is required and sold separately; choose sufficient coverage and appropriate protection for your actual excavation.

Can I use a square sheet for a curved pond?

Yes. The flexible sheet can follow a prepared curved excavation, provided both full contour measurements fit with the edging allowance and ±5% cut-size tolerance accounted for.

Will it line a 5m × 5m pond opening?

Do not choose from the opening dimensions alone. The pond's depth, sides, shelves and edge finish need additional material in both directions. Measure the complete routes through the excavation first.
