The Custom Pro 20 mil PVC Pond Liner and Underlayment Combo Kit makes installing your backyard pond easy and economical! The PVC (polyvinyl chloride) pond liner can be safely used in any kind of water feature, including one with fish and/or aquatic plants. The liner is manufactured in 5 or 10 foot panels and therefore may include factory installed seams for most sizes. Buy with confidence because the entire liner is covered by a 5 year manufacturer's warranty against defects or failure!
 
This PVC pond liner's black color provides a natural look and the illusion of greater water depth. Highly flexible, this 20 mil pond liner is much more durable than cheap 14 mil "Pond Skin" liner commonly sold. Superior flexibility allows you to fit this 20 mil pond liner to the various contours of your water feature. Tip: Always cover any exposed liner with soil and stone to protect it from UV light, create a more natural look and ensure years of service! 
 
The non-woven geotextile underlayment protects your pond liner, helping to prevent damage that could require repairs. It increases puncture resistance over 500% compared to PVC used without underlayment! Place the underlayment between the soil and liner to guard against sharp objects, roots and burrowing animals.

    Very pleased with this product. Built a small backyard stream and it was easy to work with and seems heavy duty. I installed it myself. Good price for underlayment and liner.

    Easy to trim and stood by up to New Mexico sun.

    I used this to construct a water basin for my cloth planter bags. Th dry high desert conditions are extremely hard on vegetable gardens. This pond liner allowed me be able to capture rainwater for use by my planters. It stood up to the arid environment and the sunshine UV rays.

    Heavy duty and tough

    Posted by Detached Retina on Nov 30th 2022

    My side strip of lawn that runs along side the garage is torn out. I sloped the soil away from the house. I layed this pond liner down and filled the area with decorative small 3/8's pebbles and set flagstone down to fill the area. I poked holes to allow some moisture from the rain to get into the soil. Texas soil can shift under foundations here. This is a sure way to manage the moisture. I saved money since the large big hardware stores only have 12 mil . this is 20 mil and it's going to last. The sizes have more options on this site as well.
