The Problem: Not All Excavation Methods Are Safe or Site-Appropriate
Digging in the wrong location—or using the wrong tools—can lead to major setbacks: damaged utilities, safety violations, soil erosion, or expensive restoration. Traditional excavation is often too aggressive for sensitive environments, underground congestion, or limited-access jobsites.
Contractors and municipalities need a smarter, site-appropriate solution.
The Solution: Hydro Excavation Excels in Challenging Environments
Hydro excavation offers unmatched precision, safety, and control—making it ideal for high-risk, high-traffic, or hard-to-reach projects. With TRUVAC hydro excavation trucks operated by Haaker Underground, you can dig exactly where needed without disturbing what you shouldn’t.
Top Use Cases for Hydro Excavation
Utility Potholing and Daylighting
Hydro excavation is the gold standard for exposing underground utilities without risk. It safely removes soil over fiber lines, gas pipes, water mains, and more—ideal for utility locating and verification.
Slot Trenching
This method is perfect for installing narrow utility lines, electrical conduit, or fiber optic cable. It ensures minimal surface disruption and maximum accuracy in tight corridors.
Pole and Sign Installation
Instead of augering into utility-dense zones, hydro excavation provides a safe way to dig deep, narrow holes for poles, signs, and supports—without risking buried assets.
Catch Basin and Storm Drain Cleaning
Hydro excavation isn’t just for digging. The vacuum system efficiently removes debris, silt, and blockages from storm drains and catch basins, improving stormwater system performance.
Remote and Urban Access Jobs
TRUVAC trucks feature extendable boom arms and compact footprints, making them ideal for:
- Alleyways
- Landscaped commercial properties
- Urban streets with traffic
- Hard-to-reach industrial zones
Frozen Ground or Winter Work
With onboard heated water systems, TRUVAC hydro excavation trucks operate effectively in frozen soil—making them perfect for year-round infrastructure maintenance.
Specialty Applications
