Crack Repairs and types of cracks
Pool cracks can be as short as 12" and can lead to significant water loss. Additionally, when left unattended, cracks will spread and can create significantly more damage and increased cost. The earlier a crack is addressed, the less damage it can lead to.
There are a number of different types of cracks. Each type of crack is repaired slightly differently, however, the main goal is relieve the tension that caused the crack. By simply filling in the crack, that tension is not relieved, and the crack will reappear.

As with wall cracks, there are a number of ways to repair these using epoxies and injections. However, these topical repairs will stop the leak but do not address the reason they cracked. By breaking out the damaged areas, we can stop the crack from spreading and reappearing.
