Product reviews for 5' x 100' Pond Liner Underlay Kit

I have ordered this product multiple times, and I keep coming back. I have used it as designated: as underlayment for the actual liner on several pond projects. But because it is so strong, I have used it as a structural component when restoring the bank to the pond in front of my house. It was badly eroded, both due to koi eating away at it as well as just time and weather. I use this textile as a soil barrier between the backfill and the new bank which I construct from natural stone. This textile is so tough, it acts like a reinforcement layer, tying everything together. It keeps the bank from moving due to soil pressure. I've tried some other products which were less expensive, and I got exactly what a paid for: CPOC. So, I'm back to the original.
