About Vacuum Excavation

What is Vacuum Excavation?Vacuum Excavation Photo

Vacuum excavation utilizes the kinetic energy in a high velocity air stream to penetrate, expand and break-up soil. The loosened soil and rocks are then removed from the hole through the use of a very powerful vacuum. In this way, a hole is created that is typically one to two feet square and as deep as required to expose the buried utility.

Goliath's vacuum excavation system also plays an important role in directional boring by enabling operators to know the exact location of utilities intersecting the bore path and to also remove bentonite slurry from the boring site


Our vacuum excavation provides greater safety for you by eliminating the risk of utility interruption from a backhoe, pick, or shovel accidentally striking a fiber optic cable, gas pipeline, electric power line, or water main. Small hole techniques, where the work is done from above ground through a small opening, minimizes restoration and easily triples productivity compared with conventional open pit repair and backfill methods.


Goliath Hydro-Vac, Inc. has years of experience in all aspects of underground utility installation and maintenance. This experience, along with knowledgeable people and state of the art equipment, has helped us become the leader in trenchless technology.

Due to the mobility of our equipment and flexibility of scheduling, we are competitive anywhere in the Midwest. We are confident that our years of underground utility and trenchless excavating experience can save you time and money on your next project.

Directional boring and vacuum excavation is utilized on virtually all of our projects including site utility construction, communications and demolition construction.

Excavating with high-pressure water is the method of choice where soil must be removed for observation or repair of underground pipelines, wires or other sensitive facilities. Goliath uses a fully self-contained, custom engineered vacuum truck that simultaneously excavates and removes debris. Excavation occurs at a controlled rate while the expelled material is vacuumed into a debris tank.

The simplicity and effectiveness of our vacuum excavating saves time and money without sacrificing quality. The flexibility of vacuum excavating allows us to complete many tasks that are otherwise highly labor intensive, inefficient and potentially damaging.

Advantages - Vacuum excavating offers advantages over traditional methods. Excavation with a backhoe and dump truck requires more workers and disturbs a large area even when digging a small hole. Vacuum excavating requires fewer crew members and a small, neatly excavated footprint. This technique can also be used on frozen ground using heated water which eliminates delays caused by conventional thawing methods.

In addition, the vacuum excavating unit is efficient and non-destructive. Customers appreciate the need to excavate safely, reducing the risk of injury, costly damage to buried facilities, and potential liability.

INDUSTRIES SERVED - Vacuum excavating is currently used by numerous industries. These include: General Contractors, Municipal Utilities, Gas and Electric Utilitiesk.

Vacuum Excavation at Goliath Hydro-VacWet/Dry Vacuum Cleaning

Jobs that used to take days are completed in just hours. Our custom-built vacuum vehicles can quickly cleanup the toughest, dirtiest material, no matter where it’s located.

The tremendous suction generated by our equipment ensures the fast removal of wastes and debris without stirring up dangerous particles or annoying dust. Metal chips, slag, steel shot, wood chips, sawdust, grain, mill scale, slurries, sludge and water are just some of the materials that can be removed quickly and efficiently.

In addition, some of our vacuum vehicles have remote cyclone units attached. These units are used to discharge the vacuumed material directly into a vessel of your choice, saving substantial time and money.

Our vacuum vehicles operate at 3200 to 7500 cfm and at 18 to 27 inches of Mercury, and can move very heavy, wet or dry sludge long distances. A bag house unit filters and controls the air discharge for the vehicle, as well as an ancillary option of a HEPA filter unit that filters the air from the vehicle before it is discharged into the atmosphere.

Our fleet of vacuum vehicles includes those equipped with hydraulic sludge pumps and vacuum roll-off equipment that allow cost-effective simultaneous vacuuming and offloading of material.
