What is Hydro Excavation?

Hydro excavation is a fast, safe, and environmentally-friendly method of digging and soil removal. Instead of traditional tools, hydro excavation utilizes pressurized water and a vacuum system to break up and remove soil. Crews commonly use hydro excavation (often referred to as daylighting, potholing, or non-destructive excavation) for trenching, digging new utility holes, and uncovering existing pipe systems with minimal risk of breaks or tears.

How Does Hydro Excavation Work?

During the hydrovac process, pressurized water is injected into the ground to safely wash soil from the underground area. As the soil cover is liquefied, the resulting dirt slurry is simultaneously extracted by a powerful vacuum, leaving a trench completely open. The extracted soil runs through a large debris hose and is stored in a 15-yard debris tank on the hydro excavation truck. 

After the work is complete, the slurry can be released from the holding tank and put back onto the ground to refill the trench or, if there is not an on-site area to dump the soil, off-site disposal can be arranged. By digging the trench to specifications, the costs for backfill, concrete encasement, and asphalt patching are minimized.

Hydro excavators require a 2-inch water fill source, such as a fire hydrant or water truck; if you do not have a water source available, we can provide one.

Advantages of Hydro Vacuum Excavation

Sometimes traditional tools for digging and excavating, such as shovels, drills, and backhoes, are not the right option for certain areas. The use of traditional tools can be time-consuming, less accurate, and potentially risky – especially when underground utilities are present.

Hydrovacing, on the other hand, is a practical alternative excavation method that offers many benefits:

  • Effective anywhere, any time – Our powerful hydrovac systems can dig through tough grass and all soil types. With the aid of onboard heaters, our hydrovacs provide safe and effective means of digging in frozen ground, allowing construction and repair projects to continue throughout the colder months.
  • Can handle a variety of projects – We can excavate up to 60 feet deep and the hydrovac truck can be positioned 600 feet from the actual excavation area. This enables work to be done in areas of limited access and lessens traffic and congestion at the excavation site.
  • Accuracy – Our operators use a handheld pressurized wand to direct the stream of water. The wand is small and flexible, allowing the crew to easily maneuver around tight quarters and nearby obstacles like streetlights, signs, and adjacent utility systems with minimal disruption.
  • Safe – Traditional methods of excavation involve labor-intensive techniques and equipment that come with additional risk factors such as falling debris and cave-ins, creating hazardous conditions. However, hydrovacing provides a safe way to complete excavations; it does not require a worker to be inside the trench controlling the excavation equipment and the surrounding soil is not disturbed, reducing the cave-in fatalities. Since hydro excavation uses water, it is a non-hazardous medium used for digging holes and trenches.
  • Less damage – Traditional excavation equipment such as heavy backhoes or sharp, metal drills can easily tear through underground utilities and damage pipes, often causing service interruptions. Hydrovac excavation is a gentler, more controlled way of excavating that minimizes damage to existing infrastructure and won’t disrupt or delay the site with costly repairs.

Hydrovac Applications

Debris Removal

Our hydrovacs can be used to remove debris and clean areas without affecting existing infrastructure. If it can fit through our 8-inch diameter hose, we can remove it! Our powerful vacuum and 600-foot hose allow us to reach remote locations and clean up the impacted area. This includes sludge pits, underground detention basins, retention ponds, drill mud, and more.

Potholing & Daylighting

Rather than risk cutting into buried and hidden utility lines, our hydrovac technicians can use the precision soil removal capabilities of our state-of-the-art equipment to effectively uncover those lines that you know are there, and those you don’t! It’s the best way to expose underground utilities, check for cracks, leaks, or any kind of damage, and will keep you from making the costly mistake of digging without first identifying potential trouble.

Slot Trenching

Slot trenching is the process of digging narrow trenches for installing pipes, cables, or other in-ground utilities. Hydro excavation provides a non-destructive and efficient slot trenching method even on frozen surfaces. It eliminates the potential for serious and costly damage often caused by traditional slot trenchers. Hydro excavation makes it easy and safe to install sprinkler systems, locate underground utilities, and perform similar installations without the risk of damaging existing underground systems or lines.

Pole Installation

Vacuum excavation for hole digging is faster than manual digging and reduces the risk of damaging underground lines and pipes during excavation. We can dig holes for all types of utility poles, including power poles, light poles, telecommunications poles, traffic lights, signposts, and more!

Culvert & Sewer Cleaning

The combination of high-pressure water and our powerful vacuum can clean out hard-to-reach areas like culverts, sewers, and storm drains.
