Heavy duty

Worked great for the pond liner

Our outdoor pond has had a leak for about a year. We have been constantly filling it with more water every day so that our turtles and fish do not die. When we saw this item, we purchased it right away and have been so happy. It is such a relief not to have to worry about our pond animals. We just lined the pond with this and pressure of the water keeps it in place. Our fish and turtle are happy and we are happy.

I got this thinking it was a tarp but it is a pond liner. It however works well as a tarp too. Had something outside that needed to be covered long term and this hearty tarp works well for it. Good item.

I found the material extremely hard to work with. Most of the liners that I have used in the past are more of a rubber texture and capable of somewhat molding or stretching to the non-conforming shapes and challenges of a pond. This was like a giant tarp or slip-and-slide. I'm almost to the point of scratching the whole thing and ordering something else.

This liner is made pretty well. The durability varies based on climate and substrate. We have sandy soil, so it seems to be doing well. The liner isnt very thick. To avoid leaks, I always use a pad or liner-pad underneath to add that extra layer of protection. 10x15 seems large, but it goes quickly. We have a nice water feature using two spill overs to fill the basin, lined with this liner. Definitely recommend installing in the warmer months to avoid creating creases in the liner(which cause weak spots). Let it sit in the sun for 20-30min at least and it will be easy to lay in the hole.

This is a really thick and durable pond liner that was easy to use and seems to be great value for the money. We have not had any issues with leakage yet and it was incredibly easy to set up.

I am planning to use this to line my wooden whiskey half barrel to turn it onto a pond. It is a little stiff, so I can see that I will really have to work with this liner to get it in there, but once in, I believe it will do a great job holding water.It is thin yet feels very durable.
