Excavation is the process of digging the hole for an inground pool. Depending on the size of the pool, this can be an extensive process, involving large machinery and specialized skills. In addition, care must be taken to avoid water or gas pipes, as well as remove the excavated materials.

One critical factor in the excavation process is the makeup of the material being removed. Obviously loose soil is much easier to dig than rock. The excavation crew will examine the area to be sure that they know what might be entailed. The ground will also determine the cost of the project. Chipping through solid rock is more costly than a simple dig into soil.

Responsible excavation crews will research where gas and water lines are, to avoid accidentally puncturing them. This requires a call to the local utility authorities. In addition, removed materials must be deposited according to local regulations. Not all dumps will accept all materials.

Depending on the water table, it is possible to hit ground water during an excavation project. In this situation, it may be necessary to elevate the pool. An alternative is to install a dewatering system, which will keep the excavation site dry during the pool installation. It’s important to check with local regulations to be sure that this choice is lawful.

Even when crews are careful, yards and surrounding areas will likely incur some damage due to the large trucks and other machinery used in excavation. Be sure that any necessary repairs are covered by the pool installation or excavation contract.
