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?

Got to admit, I've gone off taking much notice of guarantees. Anything more than a year is, in my experience, not worth anything. Happy to read about others finding them of any use. (not just liners).
Mine is butyl rubber. Was doing fine for several years until something (badger I think, but may have been a fox), ripped several chunks out of the top sides. It's above the waterline, so not a disaster, but unsightly.
Not sure how a 40 year guarantee would work. Do they expect you to send it back after 27 years to prove it's failed when used as instructed?

We bought a carpet with a 10yr guarantee when we first got married & the shop shut a month later!! I agree that guarantees are worthless generally. However it is an indication that it might last 10 years. It seems to be more puncture resistant than butyl. I'm tempted because it's a lot lighter & therefore probably easier to manage. I could buy a lot of other things with the 100 euros saved too!
P.S. Swarovski repaired our scope for free that we had bought from my cousin. It was about 15 yrs old & had dust inside. Paid for the P&P too!
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!
In reply to Noisette:
'Windows'....they're a good example of long guarantees working. I knew there was something!
Personally, I'd stick with butyl, esp as the guarantee of the proposed alternative far exceeds the time the company has been in business, but good luck if you go for the cheaper option.
Thanks Robbo, it's still in the balance!
I used butyl for my pond and felt confident in the thickness and feel of it. It probably depends how you go about setting up your pond, I knew that I had plans to place large stones on top of the liner so the heavier the better for my particular needs.
