This is a 15' x 20' pre-cut piece of 8oz Geo-Cushion.

Geo-Cushion is an 1/8" thick (approximate) pad that is placed on the ground before your pond liner is installed. It acts as a barrier to protect your pond liner against punctures from rough surfaces on the ground (rocks, dirt clods, sticks, etc.) NOTE: You should make every effort to prepare the ground to reduce/eliminate all sharp objects before installing any pond liner (with or without the use of an underlayment).

Please contact us if you have any questions on how to calculate the size your project requires.
