Two years ago my wife and I successfully constructed a garden wildlife pond and have enjoyed it ever since. It has been a wonderful attractor of birds and other wildlife including dragonflies, damselflies and other insects which in turn have attracted bats.

This winter the friendly neighbourhood foxes decided it would be great fun to check out what is under the surface of the water. The result is that they have ripped the pond liner with either their teeth or paws. The rips in the fabric have also resulted in the water level dropping to below the damaged area which obviously is in the shallow area. Has anyone any experience of repairing such a mess? The pond liner is of a standard heavy polythene type. Any help would be much appreciated.
