what do you guys think about a heavyduty tarp as pond liner?

Question

i should have already told you its been up n running 4 a month now no big problems just wanted yer guys 2 cents or any other tips

Answer 1

As a landscape designer specializing in water gardens, I must say I have often wondered about this myself.
Don't expect it to last as long as that 40 gazillion dollars a sq ft stuff, but I think if you at least dbl layer it you'll be fine long enough to decide if you want to invest in the long term expensive stuff. Honestly, I think most most people lose interest long b4 the a cheap tarp would start to leak. I'm sure it will be waterproof for a season at the very least. If you're still into it after that, double bag it next year. By then you'll know if you want to upgrade to the crazy-expensive rubber stuff.

P.S. I highly doubt any cheap tarp would be all mildew resistant. Do not worry. I'm sure you're fine. People worry and over think too much. Drama queens.

Answer 2

It would prbably work for a while, but I have to believe that in a few years your pond could dry up. Most tarps I've seen wouldn't last that long burried under a biologically active environment. (i.e fresh water pond with plant life micro organisms, fish etc...)

Hope this helps.

I would do some research into what would last and what would not.

Answer 3

a friend of mine did that -- a molded plastic liner is easier. the edges of the tarp were a constant problem. maybe someone has a way to hold down edges permanently but the solid edges of a molded pond seem to work a lot better as far a i can tell.

Answer 4

The tarp wont last very long before it starts to disintegrate and rot away - then, the water will all leak out.

Pond liners are designed differently so as to last longer - years longer.

Answer 5

I wouldn't suggest it as a good option at all. First for the reasons already given, but also because many tarps are treated to be mold and mildew resistant as well as fire resistant and those chemicals can kill the fish.
