Sounds good I will research them.
What about pond liner is 30 mil good?

30 mil for epdm No, 3O MIL FOR HDRPE I BELIEVE IS A MEDIUM density

It does not require underlay in most uses. No project is too big or too small for our teams. HDRPE pond liner is resistant to a variety of weather and water conditions. Our pond liners can be repaired or patched.
