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!
