The Problem: Traditional Excavation Is Risky, Costly, and Invasive
Excavating around underground utilities, pipelines, or sensitive infrastructure is no small task. Traditional digging methods—like backhoes or hand shoveling—come with high risks:
- Utility strikes causing power outages or gas leaks
- Unstable trenches putting worker safety at risk
- Expensive restoration of disrupted surfaces
- Slower, labor-intensive processes
With municipalities, contractors, and utility providers seeking safer and more efficient excavation methods, the industry needed a better solution.
The Solution: Hydro Excavation from Haaker Underground
Hydro excavation is a non-destructive digging process that uses high-pressure water to break up soil, which is then immediately removed by a powerful vacuum system. It allows operators to dig with precision—without damaging buried infrastructure.
At Haaker Underground, we use advanced TRUVAC hydro excavation trucks to deliver this safer, smarter solution across California, Arizona, and Nevada. Whether you’re exposing fiber lines, trenching for utilities, or digging in high-traffic areas, hydro excavation minimizes risk and maximizes control.
How Hydro Excavation Works
- Pressurized Water Jetting – A controlled stream of water is directed at the ground, loosening soil and creating a manageable slurry.
- Vacuum Extraction – Simultaneously, a high-powered vacuum hose sucks up the slurry and deposits it into a debris tank on the truck.
- Precision Digging – The operator controls both water and vacuum from a safe distance, maintaining accuracy and reducing the chance of damaging underground systems.
This technique is perfect for potholing, daylighting, utility verification, and slot trenching. Plus, it’s effective in all soil types—including frozen ground when heated water is used.
Key Advantages of Hydro Excavation
Safe for Utilities
Hydro excavation virtually eliminates the risk of utility strikes. No metal blades, no aggressive digging—just controlled, water-powered excavation.
Minimal Surface Disruption
Since the process is surgical, it requires far less restoration work compared to traditional digging. Sidewalks, landscapes, and roadways remain largely undisturbed.
Faster Project Completion
Haaker Underground’s TRUVAC fleet reduces the number of crew members and time required to complete excavation tasks, improving jobsite efficiency.
Cold Weather Performance
Hydro excavation works even in frozen soil using onboard heated water systems—perfect for year-round use in colder areas of our service region.
Environmentally Friendly
The process uses only water and air—no harsh chemicals or fuel-powered mechanical digging—making it a cleaner alternative.
Applications for Hydro Excavation
- Potholing & Daylighting – Expose utilities safely for inspection or verification
- Trenching – Create narrow trenches for cable or pipe installation
- Debris Removal – Clear clogged catch basins and storm drains
- Pole & Sign Installation – Excavate tight, deep holes without damaging nearby infrastructure
- Remote Access Excavation – Reach hard-to-access areas with extended boom reach
Whether you’re in construction, utilities, telecom, or municipal services—hydro excavation is a game-changer.
