George,

I did not mean to use the silt-screen as a liner BUT as a rubber liner
protection. I noticed that when I cut the silt-screen it is very tuff.
So I assume that it would prevent rocks from pushing through.

Anyone still use old carpeting?...I have lots of it available.

You could use old carpeting. I used an old, thick tarp.
