Overlayment Question

[ATP]

Just received my overlayment yesterday, which was supposed to be 7 oz and it very well might be. My concern is it feels more like a thin fleece blanket and I can easily make an indentation in it with my finger. It would take quite a bit of pressure to actually pop a finger through it, however. The only thing i have to compare to it is a heavy duty fabric that my matrix blocks were wrapped in, which I cant make an indentation at all with that fabric. I have my underlayment coming today which is 8 oz, i thought this 7 oz would work for the overlayment but now I am second guessing it.

Thoughts? Do i use it or return it and order something else?

Do you mean underpayment?

I think you meant to say underlayment. No, I am planning on using this to go over my liner to protect it from the rocks I will be adding.

I think you’ll be just fine with what you have.

Agree with @combatwombat it should be fine. Just be careful setting your rocks. I managed to puncture my liner with 8oz non woven underlay and 8oz non woven over the liner as well. It wasn’t even a large rock that I set with the excavator, it was a little 100lb one that sat on a pebble or something in the dirt.

Great! How did you find the leak?

Let the water drop until it stopped then started checking around the waters edge, fortunately I found it quickly. I was envisioning it being behind a large rock that would need an excavator to move.

RUN THE 70Z over the whole pond but take an extra piece and slip it under the boulders if you have any. It's not the ability to make an indentation that's the gauge it's the puncture ability. If you can poke your finger through that fabric somethings wrong even cheap stuff from home depot garden center is tough enough your not putting a finger through it
