Vacuum Excavation
VACUUM EXCAVATION SERVICES INCLUDING UTILITY TEST HOLE POTHOLING,HYDROVAC EXCAVATION AND TANK DEBRIS REMOVAL
Vacuum excavation provides a safe and non-destructive method for for safely and efficiently digging in infrastructure critical areas or areas where conventional excavating equipment can not reach. Once the roadway or hard-scape surface is cut and removed, typically by precise coring equipment, pressurized air or water is used to break up the soil while a high suction, PTO driven vacuum unit is used to evacuate the debris depositing it into the storage tank. This method has become the industry standard for digging precise utility test holes (potholes) for documentation purposes, exposing utilities during construction or precise trenching or pole hole excavation with virtually no risk of damage. With this level of Damage Prevention, everyone benefits.

Vacuum Excavation Services Examples
Utility potholing
What is Utility Potholing?
Potholing, also referred to as Utility Test Holes or Daylighting, is a proven and trusted method for positive verification of utility location, depth, size, material and condition. The collected data and pictures are used for design purposes as part of the Subsurface Utility Engineering or SUE process. The exact utility location is surveyed allowing for accurate depiction in design plans so that the utility can be avoided through efficient design, or moved if necessary, prior to construction.
SLOT TRENCHING
What is Slot Trenching?
Slot trenching using the hydrovac excavation method allows for digging a very precise and controlled trench to exact specified depths in tight constraint areas, crowded utility corridors or areas with highly critical existing underground infrastructure. This method can also be used to expose lengths of an existing utility for inspection, replacement or repair, or to “clear” an area by performing a perimeter slot trench to ensure that no utilities pass through.
POLE CLEARING HOLES
What are Pole Clearing Holes?
In addition to excavation pole holes for signs, fence posts, bollards and the like using hydrovac excavation, a “clearing hole” can be performed prior to construction for planning purposes. This ensures that the pole can be placed in a location during the construction phase and safely and quickly excavated with an auger at that time. Essentially the area is “cleared” by using hydrovac excavation to dig 2 intersecting slot trenches in an X shape to confirm that no utilities pass through the area.
Hydrovac Excavation
Hydrovac Excavation is a safe and efficient excavation method that is optimal for hard or rocky soils, clay or caliche, and soils laden with large cobble. The high pressure water wand is proficient in breaking up the tough soils quickly while remaining safe for exposing utilities. Spoils are extracted quickly and efficiently by the units high-vacuum slurry extraction pump generating an extremely high negative pressure with CFM flows in excess of 4400 cu ft per min. Hydrovac Excavation is recognized as the most efficient vacuum excavation method in terms of volume of material extracted and can reach to depths in excess of 20 ft and support remote hose excavation for hard to reach areas. While Hydrovac’s wet excavation process renders the extracted spoils unsuitable for immediate reuse as backfill, the gain in productivity far outweighs the cost of the backfilling.
Air Vacuum Excavation
Air Vacuum Excavation is a safe excavation method, primarily used for utility potholing. , and efficient in loose or sandy soils or shallow digging up to 8 ft in depth. Its use of compressed air ensures minimal disruption to the site and the spoils can be reused as backfill if allowed by the governing agency. Typically all holes in roadways must be backfilled with an agency approved flowable fill. Air excavation is also the choice for areas where cultural artifacts may be expected. This method preserves the extracted materials so that they can be examined for artifacts before disposal or reuse.
