Description
A square liner and underlay for your pond project
This bundle brings together a nominal 2.5m × 2.5m black PE pond liner and separate 50gsm fabric underlay. The 200gsm polyethylene sheet provides 6.25m² of flat liner material before allowances for the pond shape and edges. It has a black face, a grey reverse and flexibility for following a prepared excavation.
Allow for the pond below the surface
The sheet is 2.5m square when laid flat. Some of that material is needed for the sides, depth, shelves and the edge finish, so it will line a pond with a smaller water surface.
Measure through the actual contours in both directions, adding the material you need at the perimeter. Account for the ±5% cut-size tolerance when choosing your liner. A flat area of 6.25m² does not, on its own, establish whether your layout will fit.
Fabric first, then the liner
The underlay belongs beneath the PE sheet on smooth, prepared ground.
Remove sharp debris
Clear stones, roots and other sharp objects from the base, sides and shelves. Smooth the contact surface before bringing in the layers.
Position the underlay
Arrange the lightweight fabric beneath the liner and check its coverage around corners. Choose any further protection to suit the actual ground conditions.
Follow the shape
Let the PE liner settle into the excavation without pulling it tight across gaps. Retain the planned edge allowance and check the sheet before filling.
What is in the bundle?
One nominal 2.5m × 2.5m black and grey 200gsm PE pond liner, supplied with 50gsm fabric underlay. The PE material is UV-resistant for outdoor pond use. The two GSM figures describe different layers; they are material weights per square metre, not thickness measurements.
Pond edging, plants, stones and installation accessories are not included.
Before you order
Can the finished pond be 2.5m square?
No. The nominal sheet dimensions also have to cover the sides and depth, with material left for the edges. Measure the full routes through your planned pond before choosing a liner.
Do I need to buy fabric underlay separately?
This bundle includes 50gsm fabric underlay. Prepare the ground carefully and assess whether your particular conditions need further protection; the lightweight fabric is not a guarantee against every puncture.
