Why use vacuum excavation?

Vacuum excavation virtually eliminates the danger of damaging underground utilities, while mechanical digging with hand tools or backhoes can cause damage to those utilities.

Vacuum excavation is less invasive than traditional methods of digging. It also offers lower cost with a higher level of precision with less surface restoration needed.

There are costs involved when striking an underground utility so by using vacuum excavation instead, you could eventually save cost and save lives within your company and in the community.

Vacuum Excavation allows for workers on site to stay safe on the surface and helps eliminate accidental line damage and trench cave-ins. With vacuum excavation, companies and municipalities have an alternative to hand digging and a much safer way to expose utilities. Vacuum Excavation is the best method of identifying the accurate depth and location of an underground utility.

What is the difference between Hydro and Air Excavation?

Hydro Excavation is the process of safely uncovering underground utilities utilizing high-pressure water along with high-speed vacuum. Hydro excavation is faster than air excavation and is considered the most efficient type of vacuum excavation. Hydro excavation does not allow for the re-use of the spoil material for refilling the hole.

Air or Dry Excavation is the process of using compressed air to disturb the earth’s soil which is then vacuumed up into a debris tank. Air excavation can be slower than hydro excavation, but it does allow the debris to be used back into the hole.

Explore the benefits of our Air Vacuum Trucks for cleaner and safer excavation

Air excavating units excavate like a hydrovac without the mess – and most importantly without the disposal time and costs. This unit can be utilized in place of a hydrovac on any project that requires a hydrovac.  

There are many advantages to using this unit. First and foremost, the waste is dry so it can be left on site, saving disposal and unnecessary travel charges. The removed fill can be put back in to place and tamped if required to return the excavation to pre-excavated condition.  Since this unit doesn’t use water, the excavated hole is dry for a safer and cleaner working environment. 

Completely eliminate the time and costs associated with mud hauling and disposal.  Think of how much more time will be spent on the job doing billable work rather than traveling back and forth to a dump site to get rid of all that mud created by a hydro excavator.  You’ll also appreciate the fuel savings.

Sub Surface Utility Location Services (Potholing)

Discovery’s Subsurface Utility Location Services (also known as potholing or daylighting) is a non-mechanical process that enables underground utilities to be exposed and documented before any construction or installation project begins. This provides the exact horizontal and vertical location, type and depth of all existing utilities that are currently in the ground that need to be located before any new construction project begins. 

Our process is fast, precise and reduces project costs related to the risks caused by inaccurate underground information. Using our air and hydro excavation services does less damage to the surrounding soil than mechanical excavation which minimizes site restoration and expense.

Hydro Excavation

Discovery Hydrovac offers industry leading hydro excavation services – available today! It is a non-mechanical, non-destructive process that virtually eliminates any risk of underground utility damage. 

Our hydro excavation is safer, faster, more precise, and cost effective compared to traditional digging. It also requires less backfill, labor, restoration and has less environmental impact than traditional techniques.

Air Excavation

Discovery also provides the benefits of air excavation services. Air excavation can be used anywhere and provides the same benefits that hydro excavation can offer. It is also a non-mechanical, non-destructive process that virtually eliminates any risk of underground utility damage. 

Air excavation is safe, fast, efficient and more cost effective than mechanical digging. Also, since the native soil is dry, it can be vacuumed and then immediately used as backfill which negates the need to haul mud away and return with dry dirt fill.

Ground Penetrating Radar

Ground Penetrating Radar (GPR) is a preliminary locating service that scans the location of horizontal underground utilities and structures. GPR is the most reliable scanning technology available. It images objects and structures (both metallic and non-metallic) embedded in soil, rock concrete, asphalt, and fresh water – any non-metallic material. 

This process is fast and reliable providing our clients with a comprehensive pre-construction map of the sub-surface utility landscape.
