Description
Choose the sheet around the pond you are planning
Our black and grey 200gsm PE pond liners are available in seventeen square and rectangular cut sizes. Each selection supplies one flexible polyethylene liner, from the compact 1m × 1m sheet through to the 10m × 10m square. Choose by the full measured route through your excavation, rather than the water surface alone.
Square or rectangular?
A square sheet gives equal starting dimensions in both directions. A rectangular sheet can suit a layout needing more length than width. Neither shape fixes the finished pond dimensions: depth, shelves, folds and edging all use part of the material.
Square sheets
1m × 1m; 2.5m × 2.5m; 3m × 3m; 4m × 4m; 5m × 5m; 6m × 6m; 8m × 8m; 10m × 10m.
Longer, narrower sheets
1.5m × 5m; 1.5m × 10m; 2.5m × 3m; 2.5m × 5m; 2.5m × 10m.
Other rectangles
3m × 4m; 4m × 5m; 4m × 6m; 5m × 6m. Use the Size menu above to select an option and see its price and availability.
Measure through the pond
Check the longest and widest routes through the excavation, following the actual base, sides and shelves. Include the material needed to finish and secure the edges. Check both directions: spare length cannot compensate for insufficient width.
The dimensions in the menu are nominal cut sizes and can vary by ±5%. Leave enough allowance when choosing, rather than planning an exact fit from the stated dimensions. Flat sheet area alone cannot confirm the fit of an irregular pond.
Prepare first, then position the liner
Every size needs suitable underlay and a smooth, supported surface beneath it.
Smooth the ground
Remove sharp stones, roots and debris from the base, sides and shelves. Do not rely on the liner or lightweight fabric to cover sharp objects.
Arrange the underlay
Choose protection suited to your ground conditions. Plan the pieces and any overlaps so the liner rests on the prepared layers.
Allow for the shape
Lay the PE sheet without stretching it tight across corners or gaps. Keep enough material for the edge finish and check before filling.
What is supplied?
One black and grey 200gsm polyethylene liner in the size selected. The PE material is UV-resistant for outdoor pond use. This is a liner-only range; underlay is required and sold separately. Edging, plants, stones and installation accessories are not included.
Questions about the range
Is the larger liner a heavier material grade?
No. All sizes on this page are 200gsm PE. A larger sheet has more total material, but the weight per square metre is the same. GSM is not a millimetre thickness measurement.
Does ordering two create one larger sheet?
No. Each quantity is a separate liner in the selected cut size. Joining materials are not included. Choose an appropriate single sheet size where your installation requires one.
How do I choose the underlay quantity?
Plan its coverage across the prepared ground beneath your chosen liner, including the sides and shelves. Account for the arrangement of each piece and any overlaps. A flat area total alone does not tell you how many pieces will fit the layout.
