Frequently Asked Questions

How long does the excavation take?

Soil conditions will play a major role in the speed at which a pothole can be created. The harder the soil, the longer the time it will take to reduce and remove it from the excavation. It could take from 10 to 15 minutes to excavate a hole 6" to 8" in diameter and 4' to 5' deep in extremely hard soil conditions.

However, the same excavation will require only 2 to 5 minutes in average soil conditions. Our Reduction Tool design and patent pending nozzle configuration, cuts peripheral clearance as it blows out  the core of the hole. The nozzles that cut the core actually cut in advance of the reduction head itself. This cutting action allows for the exposure of the complete utility as opposed to exposing only the top of the service.

How does water compare to air excavation?

Two of the most prominent means of excavation are hydro (water) and pneumatic (air). Currently most of the systems on the market utilize the hydro excavation technique for non-destructive location of buried utilities, for the following reasons…

• Digs faster in a variety of soils
  
• Does not create a dust cloud when digging
  
• One man operation using proper digging tools, as opposed to the two man air lance and vacuum system
  
• Inexpensive filtration
  
• No air compressor required
  
• Spoil removed from site
