Excavation

Underground utility infrastructures are becoming more and more congested and complicated as they compete for limited space to accommodate ever increasing demands. Consequently, safety as well as financial concerns have also increased as exact vertical and horizontal locations of utilities are more in demand for design and construction.

Using non-destructive water or air vacuum technology, Subtronic can quickly, safely and economically excavate in areas inaccessible to conventional digging equipment – even in sensitive areas such as around high pressure gas, high voltage electric and petroleum refineries.

A vacuum excavator works by using either high pressure air or water to break up the soil. A powerful vacuum removes the loosened soil and transports it to a holding tank where it is stored until it is used for backfill or hauled away for disposal. The excavator can create small holes (8″-10″) in diameter to positively identify the location of existing utilities or dig “slot trenches” to whatever length is necessary in heavily congested areas. Most utilities are located within 4-5 feet of ground surface and can be safely exposed within 10-15 minutes depending on soil conditions. While this is true for many utilities, Subtronic’s vacuum excavation rigs have the ability to dig holes to over 20 ‘deep to find even the most difficult utilities.

Advantages of Vacuum Excavation over Hand Digging:OLYMPUS DIGITAL CAMERA

  • Even with hand tools it’s easy to damage a buried utility and, of course, backhoes are notorious for causing utility accidents.
  • If the utility being located is under a street surface the 1ft x 1ft pothole created by a vacuum excavator is much faster and easier to patch than the much larger hole left by hand digging or a backhoe.

  • Exposing underground utilities.
  • Excavation in sites to small for excavators or backhoes
  • “Slot trenching” in areas with many utilities.
  • Environmental monitoring well installations.
  • Installing cathodic protection.
  • Street sign installations.
  • Footing excavations.
  • Fence or barricade installations.
