Pool Shell Crack Detection & Repair

Cracks in a pool's gunite shell or plaster surface are a primary source of water loss in Southern California pools, where soil movement, drought shrinkage, and seasonal temperature swings stress the concrete structure over time. Reseda Pool Leak Detection uses dye injection testing — introducing a small stream of colored dye near a suspected crack and observing whether it is drawn into the surface — to confirm active leaks and distinguish them from purely cosmetic surface fissures.

Once an active crack is confirmed, we document its location, length, and depth before recommending the appropriate repair method. Minor surface cracks in plaster may be sealed with hydraulic cement or epoxy injection while the pool remains filled. Structural cracks that penetrate the gunite shell may require partial dewatering and a more involved repair process. We explain all options clearly and help you understand the tradeoffs between a temporary seal and a long-term structural solution.

Leaving shell cracks unaddressed allows water to saturate the surrounding soil, undermine the deck, and accelerate further cracking as the shell flexes. Our team serves the Reseda area and surrounding San Fernando Valley communities seven days a week, making it easy to schedule a crack assessment before minor damage becomes a major structural problem.
