Description

A flexible liner with fabric underlay for the layer beneath

This bundle pairs one nominal 2.5m × 3m black and grey pond liner with 50gsm fabric underlay. The 200gsm polyethylene sheet is flexible enough to follow a prepared excavation rather than a fixed preformed outline. Its nominal 7.5m² flat area includes all the liner material available for the base, sides and edges.

Prepare the pond for the two layers

The fabric underlay belongs beneath the PE sheet. Plan its coverage before fitting the liner, including the arrangement needed around shelves and changes in level.

Illustrative preparation. Liner and fabric underlay are included; landscaping and installation accessories are not.

Clear the supporting surfaces

Remove sharp stones, roots and debris from the base, sides and shelves. Smooth the areas beneath the protective layer.

Check the fabric coverage

Plan its layout and any overlaps. The included fabric is lightweight, so assess whether your actual ground conditions need further protection.

Ease in the liner

Follow the contours without stretching the sheet tight across gaps. Leave enough at the perimeter and check the position before filling.

Allow for the shape below the waterline

The 2.5m × 3m dimensions describe the liner laid flat. They do not describe the water surface it will line. Depth, side walls and shelves use material, with more needed for the edge finish.

Measure the longest and widest routes along the actual excavation contours, add the edging allowance and compare both with the sheet. Allow for the ±5% cut-size tolerance. The 3m side gives extra reach in one direction, but the 2.5m side must still fit its complete route.

Two materials, clearly identified

You receive one nominal 2.5m × 3m 200gsm PE pond liner and 50gsm fabric underlay. The liner is UV-resistant for outdoor pond use, with a black face and grey reverse. The fabric is a separate protective layer beneath it.

The GSM ratings are the individual materials' weight per square metre. They are not a thickness measurement or a combined liner rating. This is polyethylene rather than EPDM rubber. Edging, stones, plants and installation accessories are not included.

Questions about the bundle

Is the underlay supplied with the liner?

Yes. This bundle includes 50gsm fabric underlay with one nominal 2.5m × 3m PE liner. Plan the fabric layout, coverage and any overlaps for your excavation.

Does 7.5m² describe the finished water surface?

No. It is the nominal flat liner area. Some of that material covers the sides, depth and edges. Measure both full routes through the pond before ordering.

Does included underlay mean sharp objects can stay?

No. Clear sharp stones, roots and debris first. Check the protection required by the actual ground conditions before fitting either layer.
