Review on 16X20 Ft 20 Mil Thick HDPE Rubber Pond Liner For Outdoor Ponds, Fountains, Waterfalls & Water Gardens by Chris Budenski

While we were excited about the thickness, hoping to avoid leaks, this was way too thick for a small backyard pond. It was difficult to work with and wouldn't mold to the walls of the pond. Giant mess on our hands, had to cut areas to line our waterfall, using water sealing tape. Woke up this morning to the pond still leaking. Not a good choice for our needs, and since we installed it we can't return it. Costly mistake :(
