Pond liners are a crucial element in any water feature and a key part of
The Ecosystem Pond. It is important
to use only high quality, durable pond liner that is properly installed to prevent leaks and conserve our most precious resource – water!
EPDM pond liners (45 mil) are the preferred choice of both contractors and homeowners. These pond liners are very durable, yet flexible enough
to conform to almost any curve or corner. Pre-formed plastic ponds restrict you to only a few available sizes while EPDM pond liner allows you
to configure your pond to any shape you can imagine!
Recommended liner installation includes first installing a layer of geo-textile underlayment to protect the liner. The EPDM pond liner is then
installed and covered with rocks and gravel to naturalize the pond and also to protect the liner from UV rays. The most common practice is to
use one liner for the pond and a separate liner for the stream and waterfalls. The stream liner does not need to be seamed but just overlap
the pond liner.
Proper liner sizing is very important since seaming liner is possible but not recommended under normal conditions.
