Clear sharp objects from the pit and add a layer of soft materials like sand, newspapers, old clothes, old blankets, old liners to the bottom before laying the pond liner.

Way too thin for a pond liner

Don’t waist your time and money. This liner is not strong enough. It rips easily. After installing the liner, skimmer and had the pond filled up with water we noticed a leak on the next morning. Look at the picture for reference!

This product doesn't show the material thickness, and I don't think it's much, if any thicker than what you can get from the hardware store. There was a leak within a week. Definitely don't get this if you can afford to spend the extra for a thicker material

I got this liner to put in my pond, it’s heavy and seems thick but be careful bc adding your rocks and cinder block will scratch it up. Fortunately my rocks scratched on the outside where it will not leak. So far so good😁

Durable? What a lie. Forget all the adjectives on site and on the package, you'd be better off throwing plastic garbage bags in your pond and hope for the best. The incredible amount of energy and time spend preparing the pond revamp had to be put on hold because of this substandard joke of a product. We were so excited, having recieved the liner yesterday in time to complete our mission. Not a pebble was involved, certainly nothing that could damage or puncture a liner, and with perfect preparation and wanting to be ready to fill the pond the next day, the liner was opened up and placed at the ready for what was to be our last day where the liner gets spread, delicately smoothed out as the water fills the pond.Nope. Not only a full-on hole in the liner appearing in the first two minutes, but a slit ready to open up as we tried to re-shape the liner accordingly.We already had doubts on its arrival as to its thin-ness, and lightness of weight, but went ahead in good faith thinking that a Canadian (I believe) product would have integrity.Do not buy this piece of cheap junk. To have waited for this to arrive and attempt to finish our pond and find that hardly 5 minutes have passed before a puncture appears, despite the gentlest of procedures, makes me so angry as personally time is an issue here and now I'm having to help my friend do this next week with hopefully a better rival product, and get it done and dusted once and for all.These guys should pull this product and I expect full reimbursement for it monetarily and my wasted time to be paid for.So annoying - STAY AWAY AND DO NOT BUY THIS RUBBISH.

This product was exactly as advertised. We did just like suggested and put in sun for a little while. This loosened is up enough to maneuver a little easier to fit in the pond we dug in the back yard.
