While TerraCarta has a big amount of detection techniques at its disposal, the applications of digging a trench are wide. These trenches are mostly dug manually, but if the trench lengths are big TerraCarta uses mechanical excavation. The goal of these trenches is often a verification of the survey, or an identification of the surveyed utilities. All of our survey teams are equipped with sufficient digging equipment. After the survey, all dug trenches will be closed again, as well as the pavement being restored to original state.
