Using a new liner as a temporary fix for deteriorating pond liners offers limited benefits compared to the proper removal of the old liners. A quick solution by placing a new liner on top of an old one creates various problems that end up inflicting greater damage.
The installation of a new pond liner requires the complete removal of existing materials since it produces the best outcomes for leak prevention and longer durability.
The Risks of Overlapping Pond Liners
Laying a new pond liner over an old one might seem convenient, but it can create hidden problems. Water becomes trapped as the main critical problem when layers overlap. Pond leaks occur while liner degradation speeds up simultaneously with bacteria and algae growth.
The presence of captured moisture between the layers results in shortening the lifespan of the new liner until required repairs arise or complete replacement becomes necessary.
The dangers that caused holes in the previous liner may harm the newly installed liner because they will still pose the same risks.
Omitting the removal of the old liner prevents proper examination of the foundation area, so you cannot effectively prepare the base for maximum longevity.
Proper Pond Liner Replacement Methods
The reliable recommendation at That Pond Guy requires complete replacement methods to protect the integrity of your pond. You must start by totally removing the old liner so you can look over the pond foundation.
You should inspect every inch for debris along with sharp objects and roots that might damage the structure, then remove them correctly. To achieve an even surface for the pond, you should reshape and smooth out the floor if needed.

The lining process should start with installing protective underlayment before proceeding with the new liner. A protective underlayment functions as a protective surface which reduces the chances of liner damage while increasing its service period.
EPDM rubber liners deliver exceptional longevity due to their ability to last more than three decades when properly installed with great flexibility.
