Thought I'd have to line this liner, so the dogs nails didn't rip it, but it's thick and doesn't need anything covering it, thankfully. Glad I got this and not the more expensive 60 mil, this is plenty thick enough.
Great product. Easy to form around curves. Installed 3 months ago and so far no leaks. In order to ensure success, any pond liner must be installed over a barrier membrane that will help prevent punctures from roots and other objects.
