Vacuum Excavation

BENEFITS

FOR VACUUM EXCAVATION SERVICES

The main benefit of using a vacuum excavator is the minimum damage to existing and underground fixtures of pipework, cabling, and power or other lines. It is more precise and accurate and there is less need for backfilling. digging and collecting dirt around an underground utility or cable, without using traditional digging tools or machines.

Using non-destructive digging techniques like vacuum excavation and hydro excavation has proven to significantly mitigate the risk of line strikes and utility damage, while also decreasing project time

Safely excavating around cable networks and buried pipelines, emergency repair for utility and pipeline networks, rail track maintenance deep excavation, confined space excavation, sewer clearance, clearing around tree roots, basement work and more.

Vac Ex is commonly used for environmental maintenance, including clearing away any environmental damage and cleaning blocked gullies and gutters on the street.

THERE ARE MANY DIFFERENT TYPES OF

VACUUM EXCAVATING

Test Holes

Often referred to as "potholing" or "daylighting." It is when small holes are hand or machine-excavated to expose a buried utility when its location is unknown. It's an inexpensive and low-impact way of verifying the location of a buried utility, including its depth and dimensions.

Trenching

To create a trench surrounding a utility or other below surface elements. The trench can be made into any shape needed to properly expose the buried utility.

Slot Trenching

High-pressure air or water can be used to accurately "cut" trenches ranging from 0.5 - 2 feet wide, and up to 8 feet deep. Slot trenching is used to search for utility lines in unknown locations, as well as to prepare the ground for the installation of pipes, cables, wires, and various other subsurface elements.

Remote Excavation

Perfect for tight or hard-to-reach spaces. The vac truck is parked further away from the work area, and a long hose is used to access the space. This can also be used when the ground surface is unsafe and unstable and the weight of the truck could cause damage.

VACUUM EXCAVATION FAQS

Utility locating uses radio waves above surface to give a presumed location of a buried utility without disturbing the ground’s surface which is Level B. Vacuum Excavation is disturbing the ground in a non destructive way to expose utility lines and prove that it’s there, proving the exaction location and depth of that utility which is Level A. Utility locating does not prove the actual size and depth of the utility. So if someone is digging near an existing utility that has been marked by locating, it is the responsibility of the person doing the digging to verify daylight or prove the location of the marked utility.

Daylighting means that something underground needs to be exposed so you can see it. It’s literally shedding light into what’s below.

Both involve using jets of air or water to break up soil and ground fill that is then sucked up to clear the area. There is no clear or right answer about which is better. It depends on multiple factors about the type of job, work conditions and goals, as well as some specifics about the site. On The Mark Locators can speak with you to asses the job site conditions and what is best for that project. 

On The Mark Locators uses a precision water nozzle on a high-pressure hose, where water is jetted to efficiently clean and remove mud, slush, debris, and soil.
