Advice on Pond Liners

Well after 3 years in the new home we are now planning a pond. Its about 2,4m x 2,4m & will be about 1m deep (I hope). I've been looking at pond liners & there are Butyl Rubber ones which at O,75mm thick cost about £7 m2. Then there are Epalyn EPDM which are a bit cheaper. You can get free underlay included for the same price.

Or there are these https://www.pondkeeper.co.uk/flexiliner-5x5m-40yr-free-underlay/p2666 at just over £2 m2 with free underlay. It has a 40 yr guarantee. Am I missing something here? Is there a drawback they don't mention? Anyone know anything about them?

  • Hi Hazel, we put our pond in over 20yrs ago and so far the liner has held up, it is a butyl one about 0.5mm thick but can't remember the price. What we did though was clear any large stone/flints and put a layer of sand about an 2cm thick and then covered that with old carpet and underlay.

    Although we have large trees growing within 3mts of the pond they have not damaged the liner with their roots. I guess products have moved on since we did our pond.

  • Hi Tony, we have always used butyl one's in the past in other houses & was going to again, but it's tempting to go for new products. If I do I'll let you know how I get on!
