Over-excavating soil depths of less than three feet can be handled by overfilling the dirt, but working with a depth of greater than three feet can pose some additional challenges. Shoring, laybacking, and extra soil filling are all required when working with deep soil depths. CNC Foundations can help you complete your deep soil over-excavating project. Our geotechnical engineers can finish the process in a few days, saving you time and money. Our process keeps you from hauling, buying new, or recompacting old soil.
