Epoxy Rock Border for Vandal-Proof Pond Edging

Concrete Floor Epoxy

Two-part epoxy for concrete crack repair (gray) works. Apply sparingly at rock contact points—binds them into a monolithic edge.

Dry-stack rocks on a 4-inch concrete footing with rebar; mortar the joints but face with stone veneer. More work, permanent.

Epoxy is fish-safe once fully cured (72 hrs). Test pH after install.
