Having built several ponds the oldest one is 6 yrs old. non with leaks
here's my $.02.

After excavating the pond basin, I put 4-6" of sand down to protect from any
stones working their way up thru liner. Next, I put a heavy layer of
newspaper down. This will plug small leaks if and when they happen.

Then I buy "Carlisle" roofing fabric, (rubber), and line the pond walls and
floor with only 1 piece of fabric. You can splice, make sure you overlap at
least 6".

I use only Osage pumps and heaters in the winter time to keep the water
flowing from the water falls into the inlet to the pump.

The guy that showed me how to build a pond has ponds over 20 years old with
no problems. I have used the roofing fabric on existing ponds with newspaper
between the fabric layers, (old vs. new). Yes you have to spend some money
in the beginning but when you divide the cost over 10 - 15 years, it's
pretty cheap.


Good info. Just wanted to add what I saw on a diy show. They bought
old/second-hand blankets as their layer below the liner.
