Often referred to as "potholing" or "daylighting." It is when small holes are hand or machine-excavated to expose a buried utility when its location is unknown. It's an inexpensive and low-impact way of verifying the location of a buried utility, including its depth and dimensions.
To create a trench surrounding a utility or other below surface elements. The trench can be made into any shape needed to properly expose the buried utility.
High-pressure air or water can be used to accurately "cut" trenches ranging from 0.5 - 2 feet wide, and up to 8 feet deep. Slot trenching is used to search for utility lines in unknown locations, as well as to prepare the ground for the installation of pipes, cables, wires, and various other subsurface elements.
Perfect for tight or hard-to-reach spaces. The vac truck is parked further away from the work area, and a long hose is used to access the space. This can also be used when the ground surface is unsafe and unstable and the weight of the truck could cause damage.
