Paddling pool with leak (South Wootton PE30)

I have two paddling pools with slow leaks, Both are clean and roughly 6/7 foot x 5 ish foot. They do inflate but start to lose inflation so no longer usable as a pool unless you are good at fixing. Rather than putting in landfill may be useful for lining a flower bed, pond, under weeds?? Whatever use you can think of collect South Wootton
