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.

    although it is a lot thinner than most liners I've worked with this one does come with an underlayment which makes it extra protected from roots and rocks. Very easy to work with.

    Great buy! Arrived Early! Great price!

    Product arrived early. Bonus! ??The liner can be bit stiff when first removed from the package. I just laid it out in the sun on our lawn. It softened right up. It was much easier to mold around the rocks when the plastic was warm. The fountain held water all night. No leaks! Great buy! Fit perfect for our needs. Our goose has already been in the fountain multiple times. No rips! ????PhotoI attached a photo. As you can see. We have a lot of rock/small boulders in the fountain. The fountain isn't finished yet, but the liner is holding water and NOT riping on the rocks. ??I did use a weed barrier underneath the pond liner for extra protection to the liner. A great buy at a great price!
