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.\u003c\/p\u003e\n\u003cp\u003eAt 3 x 2.5m, or 7.5 metres squared, this gives a well proportioned garden pond of around 1.5m by 1m at 45cm deep, with room for a marginal shelf along one side. Take it deeper for fish and the pond gets smaller, which is exactly the trade-off the size calculator helps you judge.\u003c\/p\u003e\n\u003ch3\u003eNot sure what size you need?\u003c\/h3\u003e\n\u003cp\u003eBefore you order, it is worth two minutes with our \u003ca href=\"https:\/\/www.allpondsolutions.co.uk\/pages\/pond-liner-size-calculator\" title=\"Pond Liner Size Calculator\"\u003epond liner size calculator\u003c\/a\u003e. Put in your pond length, width and depth and it will tell you the liner size to buy. A liner that is even slightly short on one side cannot be rescued once the pond is dug, so it is the one thing worth checking twice.\u003c\/p\u003e\n\u003ch3\u003eFiltration and volume\u003c\/h3\u003e\n\u003cp\u003eA pond this size holds around 450 litres. Every pond with fish in it needs filtration, and the right filter depends on your volume and stocking rather than on the liner.

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.\u003c\/p\u003e\n\u003ch3\u003eSolid and smooth, not woven\u003c\/h3\u003e\n\u003cp\u003eMany 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.\u003c\/p\u003e\n\u003ch3\u003eWorking out the size yourself\u003c\/h3\u003e\n\u003cp\u003eTake your pond length 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.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLiner size: 3 x 2.5m (7.5 metres squared)\u003c\/li\u003e\n\u003cli\u003e300 g\/m2 solid smooth HDPE, approximately 0.32mm\u003c\/li\u003e\n\u003cli\u003e100% virgin high-density polyethylene resin\u003c\/li\u003e\n\u003cli\u003e5% carbon black UV stabiliser for long outdoor life\u003c\/li\u003e\n\u003cli\u003e50% more material than liners commonly sold as 0.3mm\u003c\/li\u003e\n\u003cli\u003eJoined with a heat-welded seam, as our maximum extrusion width is 2.1m\u003c\/li\u003e\n\u003cli\u003eFlexible and straightforward to fit, and easy to trim once in position\u003c\/li\u003e\n\u003cli\u003eBlack finish, supplied folded in its own box\u003c\/li\u003e\n\u003cli\u003eFree pond building advice sheet with every liner\u003c\/li\u003e\n\u003cli\u003e40 year guarantee against UV degradation*\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e*Guarantee covers UV degradation of the liner material and requires a non-woven underlay to be fitted beneath it.
