HDPE or rubber pond liner: the word on a £7 title

Updated: 22 October 2026

You are on amazon.co.uk with a folded sheet titled HDPE at about £7, and you want to know whether that is the liner a contractor welds into a dug garden pond. It is not. Here, HDPE or rubber pond liner is a name clash: these rows are pre-cut film at 0.1 mm to 0.25 mm, while butyl and EPDM at about 0.75 mm are a different product this table does not stock. Peter F. checked the listings in October 2026, without welding or puncturing a sheet. A qualifying purchase can earn us a commission at no extra cost to you. The rows sit on our [pond membrane comparison](/hub/garden-ponds/pond-membrane).

What HDPE means on these listings

On these listings, HDPE means a thin pre-cut film, not a geomembrane a contractor joins on site. The sheets print 0.1 mm on WARM&LOVE, Wooview and mawmuaw B0G3WS3WZT, 0.2 mm on YQBFTC, Hikrxya and mawmuaw B0G3WNTTYP, and 0.25 mm on QWORK. MIKIICOCO prints no thickness. UK reviews call the 0.1 mm sheets rubble sacks and bin liners. QWORK is a PVC-versus-HDPE clash at 0.25 mm, and Hikrxya is HDPE versus PVC at 0.2 mm. aotuo says rubber on the title and HDPE in the bullets, and the size lines disagree. PondKraft’s bullets say LDPE, not HDPE and not butyl. Every printed HDPE thickness here sits under a shop blog’s 0.30 mm line.

What rubber means on UK pond pages

The RHS construction page talks about butyl and PVC. It does not describe this thin HDPE film. PondLinersco’s type guide treats 0.75 mm rubber as the usual step for a standard garden pond. A Butek listing outside this comparison, ASIN B0B1QJNFYD, is 0.75 mm butyl at £144. Rubberco’s guide starts its HDPE at 0.5 mm, five times the 0.1 mm film and still not butyl. PondLinersco’s table gives HDPE an elongation at break of 12–15 percent and EPDM more than 300 percent. Those figures are theirs, not a stretch test we ran.

Where the shops disagree

PondLinersco does not describe one HDPE. The type guide lists 0.35 mm and, in another passage, says 0.5 mm is the thinnest commercial grade. Neither is the 0.1 mm film on WARM&LOVE, Wooview, or mawmuaw. Another page calls 0.35 mm HDPE easy to drape, while the comparison page talks about welding it. Drape and weld are different jobs. The bullets do not describe weld-ready edges, and we did not join any of them. On these titles HDPE means 0.1–0.25 mm film, or a blank on MIKIICOCO. Grams, LDPE, and the price bands stay on the pond liner buying guide.

Which job gets which sheet

Use the thin film for a planter or a barrel you can watch and empty. A dug pond that must hold overnight is the job to refuse. We are not calling these rows fish-safe, because a note that HDPE can be inert is not a certificate on the listing. For a dug pond you intend to keep, buy butyl or EPDM at about 0.75 mm from a specialist. This table does not stock that sheet. If you stay inside it, the step up is LDPE at about 0.35 mm, and PondKraft’s bullets name LDPE rather than HDPE or butyl. Who each listing suits is on the best pond liner page.

Common questions

Is HDPE on the title a rubber liner?
No. On these amazon.co.uk listings, HDPE is polyethylene film at 0.1 mm, 0.2 mm, or 0.25 mm, or a title with no thickness, as on MIKIICOCO. Butyl and EPDM at about 0.75 mm are the rubber sheets UK pond pages describe, and they are not stocked here. aotuo says rubber in the title and HDPE in the bullets, with size lines that disagree. Read that as a clash, not as rubber you can bury in the lawn.
Why do reviews say the sheet does not stretch?
Buyers of the 0.1 mm sheets in this set describe them as rubble sacks and bin liners. PondLinersco’s comparison table puts HDPE elongation at break at 12–15 percent and EPDM at more than 300 percent. Those figures are the retailer’s, not a test we ran on WARM&LOVE, Wooview, or QWORK. A thin film can line a planter. It will not drape like butyl into a stony hole.
What thickness is butyl usually sold at?
Specialist pages treat about 0.75 mm as the usual thickness for a standard garden-pond rubber liner. PondLinersco’s type guide uses that step for rubber, and the Butek listing outside this table is 0.75 mm butyl at £144. The RHS page discusses butyl and PVC, not the 0.1 mm HDPE film sold here. A thicker number on a trade site is still not the millimetre printed on these amazon titles.
Is PondKraft the rubber option?
No. PondKraft’s bullets say LDPE, not HDPE and not butyl. Inside this table, LDPE at about 0.35 mm is the thicker printed plastic if you are not leaving for a specialist. It is not EPDM, and it is not the welded HDPE a contractor uses. A snippet that puts butyl next to a similar line does not rewrite these bullets. If you need 0.75 mm rubber, leave this row.
Why does one title say rubber and the bullets say HDPE?
That is the aotuo listing. The title says rubber, the bullets say HDPE, and the size lines disagree, so the headline does not tell you which sheet is in the parcel. QWORK and Hikrxya show a milder clash, with PVC and HDPE both in play at 0.25 mm and 0.2 mm. Leave it if you are about to dig. A planter you can empty is a softer case, and a short sheet still will not reach the rim.
Can I weld these amazon sheets?
The welding claim sits on PondLinersco’s comparison page, and it conflicts with the same retailer’s type guide, which also talks about thinner HDPE as something you drape. Neither line describes the pre-cut 0.1–0.25 mm film in this table. A contractor welding thick geomembrane is a different parcel, and we did not join any of these sheets. Buy one piece that covers the hole, or buy a liner specified for a welded join.
