Understanding Surface Cracks in New Pool Shells: Causes & Solutions

It is not uncommon to find minor surface cracks in a newly shot pool shell. Pool shells are made from a mixture of cement, called gunite, and can develop hairline cracks as they cure and dry. These cracks are typically shallow and do not affect the structural integrity of the pool. However, proper finishing and sealing techniques should still be applied over the surface to ensure a smooth and waterproof finish. It's important to monitor these cracks over time and address any significant issues with appropriate repair methods to maintain the quality of the pool.
