Great product
Mine came in 2- 10x25 Ft. pieces .I'm using it in a 8x13 Ft.x30 inch deep pond . It was very easy to lay down by myself ,just added a couple of stones to hold it in place until I had it fitted to my configuration.

Thick liner
I got this product for a coi pond we are building. Although, the package was ruined to no fault of the merchant, it was still intact. As a courtesy to us, Amazing Pond also sent us a repair kit as a good faith offer due to UPS negligence. Thank you for rectifying what could have been a bad situation!!!! BTW the liner is thick and durable!

Cuts easy.
Bought this to lay under an EPDM pond liner in a newly dug pond in the backyard. It seems to be durable and heavy duty enough to provide protection tot he liner without being hard to handle. Cuts easy.

It works!
Used this as underlayment for a parking pad (w/ 20+ inches of stone) and did so just before we got hit with a storm that laid down 3" of water w/n 12 hours. The majority of the water was channeled into a 'french drain' and moved away from the parking area. Very easy to lay out and provided firm footing on damp/tamped earth (before stone was added).

Wrong size received
Ordered the 20×20. Received two 10x20. I don't care it adds up its not what was ordered. 2 canoes don't make a boat. Product otherwise seems like good material.

perfect for what I needed
We decided to double the size of our koi pond. Came with more than we needed, saved the rest for a neighbor who's going to add a koi pond to his yard in the spring

Bad description!
This is two 10x20 pieces of fabric, and not one 20x20 piece of fabric. Some assembly required.

Works good and quick delivery
We are building a 2,000 gallon KOI pond and used this for the underlayment. Worked good and was delivered quickly.
