AllPondSolutions Pond Liner 10 x 1m HDPE 300gsm 40yr Warranty

AllPondSolutions is proud to offer our own branded range of pond liners. This is our heavy-duty HDPE liner at a true 300 grams per square metre, made from 100% virgin polyethylene with a 5% carbon black UV stabiliser.

At 10 x 1m this is a long, narrow sheet rather than a pond-shaped one, and it is the size people buy for streams, rills and watercourses. It also suits bog filters, header pools and planted marginal beds, and it is useful as a spare length for lining a waterfall run or repairing a section of an existing feature.

Because it is a single metre wide it comes off the extruder in one piece, with no welded seam anywhere along its length.

Not sure what size you need?

Before you order, it is worth two minutes with our pond liner size calculator. For a stream, allow enough width to carry the liner up both banks and to tuck it under the edging, and remember the run will need a little fall along its length.

Sizing the pump

A stream or waterfall needs a pump matched to the width of the channel and the height it has to lift the water. Our pond pump size calculator accounts for both, and our pond filter size recommender will size filtration for the pond the stream feeds. The instruction leaflet packed with every liner covers the same ground.

Why we quote the weight, not the thickness

Almost every pond liner in the UK is sold on a nominal thickness figure. Weight is the measure you can actually verify. Cut a square exactly 500mm x 500mm from the sheet, put it on kitchen scales, and it will read 75 grams. Nothing else in this category invites that test.

Solid and smooth, not woven

Many liners sold as HDPE are reinforced woven sheet. The weave shows as a grid pattern through clear water and cut edges can fray. Ours is solid extruded film, so you get a clean black finish and nothing for water to track along if the liner is ever pierced.

Working out the size yourself

Take the length of your run and add twice the depth, plus 60cm. Do the same for the width. The extra 60cm leaves a 30cm overlap all the way round to anchor the edges. Always round up to the next size, because you can trim a liner but you cannot add to one.
