1. Make sure that the area has no unexpected barriers underground.
Make sure that the area has no unexpected barriers underground, for example rock, pipes, tree roots, ground water or sewage lines. From a budget perspective when excavating, these unexpected barriers often cause monetary and time blowouts so they’re best to be aware of them prior to digging. The best way to prepare for excavation is to contact Dial-Before-You-Dig for an assessment, as soon as you have decided where you’d like to put your swimming pool. Dial-Before-You-Dig is a free national referral service that can highlight any major underground issues, prior to construction.
