About the flexiliners
- The pond sizes are recommended for ponds with 1 metre depth.
- 15 years is the minimum manufacturer's guarantee period for Flexiliner pond liners.
- Consider buying a pondliner larger than you think you might need - it's easy to be over enthusuastic when digging! And the liner can always be cut down to size.
If you need any help or further information please contact us.

15yr pondliner 4x3
The pondliner was bought to use as a tent groundsheet, to keep our small 2-man tent floor dry and protected. And this was certainly necessary during all the rain over the weekend in the Lake District. . We had used thin foam mats under the air mattress for added insulation, so we were surprised the pondliner showed some minor wear in 2 small areas after 4 days' use. Thankfully we bought enough liner area so we can use the spare material to patch over damaged surfaces. Obviously, we're not using the product for its intended use, we just thought it might be a little more robust. But otherwise we're happy with the product.
