Liners and Underlayment
Concrete, fiberglass, plastic, rubber. With all these pond
construction options how do you know which one is the best to choose?
Your base is the foundation of the entire pond. Your decision on which
base to use should be made with a combination of factors in mind.
Quality of the material, ease of installation, durability, and budget.
We have found that for 90% of water feature construction, 45mil
fish-safe EPDM rubber lining is the best choice. EPDM liner is flexible
and easy to install. It is also guaranteed against defects by the
manufacturer for 20 years.
Furthermore, we cover our liners completely with tons of boulders and
gravel. This not only gives the appearance of a stream bottom, but also
prevents UV light from degrading the liner (especially advantageous in
sunny areas). A successful pond begins with the base... Don't cut
corners!

This soft, polyethylene fabric will last 20+ years under your liner. It is

non-slippery surface and provides protection for the liner from rocks and
other sharp objects, spreads easily, and saves time compared to using
newspaper or sand. This is a needle-punched Geotextile, and only comes in
