Relining an Old Cracked Pond with a Liner for Tropical Lilies and Fish

Good Plan

A quality EPDM or PVC liner over the old concrete is a standard, cost-effective renovation.

Critical Steps

1. Remove all sharp debris, protruding rebar, rough edges.
2. Install a protective underlayment (geotextile fabric, old carpet, sand) between concrete and liner.
3. Ensure the liner is large enough with generous overlap (you have 8").
4. Secure edges with coping stones or a timber frame.
