In the pictures below, we have a contractor making repairs on two pool cracks, one on the wall and one on the floor. As the issue presented itself, these two cracks presented themselves and both were proven to be leaking when a proper leak detection was performed. The contractor will also be refinishing the pool, but the repair he’s making here is a big mistake.
In the first set of pictures below, we see how the contractor cut the entire pool shell out around the cracks, even taking the fill out behind the wall of the pool under the deck. This is bad. When the pool is repaired, a new segment of concrete is going to be made to bond to the area that was cut, and it might for a while, but there are deeper issues here.
