Liners & Construction

Building, expanding or patching a leak. Firestone PondGard 45 mil EPDM liner, double sided butyl seam tape, patches and expanding foam for setting rock. EPDM is fish safe, stays flexible in the cold, and is what we use on our own systems.

Measure twice before ordering liner: add double your deepest point plus two feet to each dimension so you have skirt to work with.
