Test Hole Excavation

Test holes are performed to determine the actual horizontal and vertical location of existing utilities or structures at the point of investigation. Using vacuum excavation, Accumark is able to identify any potential design conflicts, and prevent any loss of service during construction.

Each Test Hole is Fully Documented

Each test hole is fully documented and reported on a test hole inventory form
