Cracks in a pool shell range from cosmetic surface crazing to structural fractures that allow significant water to escape into surrounding soil. In West Hollywood, expansive clay soils and occasional seismic activity accelerate crack formation in older gunite pools. Water Leak Detection Service uses dye testing and visual inspection under water to catalog every crack and determine which ones are actively leaking versus which are surface-only cosmetic issues.
Active leaking cracks are sealed using underwater-injectable hydraulic epoxy or polyurethane injection systems that bond to wet gunite and cure under water. For hairline cracks in plaster surfaces, we use pool-safe white or gray hydraulic cement compounds applied by hand while the pool remains partially filled. Fiberglass pool cracks receive a resin-patch process appropriate to that substrate. All repairs are matched to the pool material type and water chemistry environment.
A crack that leaks even a small amount of water every day translates to thousands of gallons of water loss per year and can gradually wash out the soil beneath your pool's shell, leading to settlement and more severe cracking over time. Early intervention is significantly more cost-effective than deferred action. Call +12134445632 to schedule a shell inspection in West Hollywood, CA.
