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.

For the money, canít complain at all! Installed and doing a great job.
Priced liner firstly at the garden centre, this was same quality but free liner and delivery and cheaper. Liner is thin but I also used sand. All in all, very happy and so will be the wildlife!
