Flexiliner Pond Liner reviews
40yr pondliner 6x5
Easy to lay very flexible
Flexiliner 6x5 40yr - HALF PRICE FLEECE
Seems a good product and should protect Pond Liner, easy to fit.
15yr pondliner 6x5
Slightly thinner than I expected, but did the job.
Pond Liner 6m x 5m 40 Year Guarantee Plus Underlay
I was initially sceptical that the underlay and liner would be good quality given how much cheaper it was than thicker butyl liner. However, the amount of underlay supplied was generous and could be doubled up, and I covered most of the pond base with old carpet. The liner was easy to install, seems robust and is, so far, fully water tight.

It is what it says. Does a good job.
40yr pondliner 6x5
Not quite as flexible as butyl, and creases from folding can be difficult to manage, even on a warm day. But at 25% of the price, this is a minor issue
15yr pondliner 6x5
This is a multiple purchase over the last 6 years, reasonably priced for me to enlarge my pond as I have evolved into koi ownership.

Not used yet but arrived promptly and well packed. I have no doubt it'll be fine.
