Pool Shell Crack Repair

Cracks in a pool shell range from cosmetic surface crazing to structural fractures that allow significant water loss and undermine the pool's long-term integrity. In Los Angeles, expansive clay soils and seismic activity make shell cracks particularly common. Finest Los Angeles Leak Detection & Repairs evaluates every crack to determine whether it is a surface plaster issue, a bond coat failure, or a through-crack in the gunite or shotcrete shell before recommending the appropriate repair method.

For active leaking cracks, we use hydraulic repair compounds, epoxy injection, or polyurethane foam injection depending on crack width, location, and whether the pool can be partially drained. Surface plaster cracks are routed, cleaned, and filled with a matching plaster mix or underwater epoxy putty. Structural cracks in gunite shells may require chiseling out a V-groove, applying a hydraulic cement base coat, and finishing with a waterproof plaster topping to restore a seamless surface.

We also address the underlying cause where possible — including recommending deck drainage corrections that reduce hydrostatic pressure. All shell crack repairs are performed with materials compatible with your existing pool finish, and we advise on the expected lifespan of the repair relative to your pool's age and condition.
