Subsurface Utility Engineering

New Paragraph

We support subsurface utility engineering projects by locating and exposing underground utilities to help manage the impact and risk on construction projects. Planning ahead saves time and money. We fully restore the job site afterwards.

  • 1. Project Management

    Our team of experts will help you solve even the most challeging site situations.  

    • Site inspection and assessment 
    • Project plan and timeline
    • Apply LEAN Thinking to eliminate wait times, duplication of work, and reduce costs to customer
    • Coordinate with other service providers
    • Monitor work execution and schedules
    • Provide updates on job site progress
    • Debrief project completion 

  • 2. Site Preparation

    • Obtain locates or use alternate locates agreements
    • Obtain required permitting  
    • Homeowner notifications when required  
    • Site hazard identification and mitigation planning 
    • Traffic control and other pedestrian signage

  • 3. Coring/Hydro Excavation

    • Hard surface road cutting and coring
    • Safe and precise hydro excavation to expose underground utilities
    • Large fleet of custom built hydrovacs with the latest technologies, optimized for fuel and operating efficiencies
    • NextGen hydrovacs are whisper quiet reducing perceived noise levels by 100%
    • Fully MTO compliant 
    • Serving communities in the GTA, Oshawa, Hamilton, Cambridge, Kitchener, Barrie, and surrounding areas
    • Dry vacuum excavation capabilities

  • 4. Restoration

    OE takes pride in making excavation look like it never happened. We fully restore the ground surface to look as good or better than before.

    • Holes are often filled with OE’s recycled premium sand product from our on-premises hydrovac soil recycling facility. 
    • Flagstone
    • Patio stone
    • Interlocking brick
    • Concrete
    • Asphalt
    • Wooden decking
    • Soft surface reseeding or re-sodding of grass

    OE’s diverse fleet and equipment include:

    • On-demand u-fill concrete trucks
    • Stone slingers 
    • Dump trucks
    • Hot asphalt trucks
    • Road Saws
    • Coring Machine
    • Other support vehicles that enable us to perform our work quickly and effectively

  • 5. Disposal and Recycling

    OE’s on-premises soil recycling facility turns hydrovac waste into reusable products that are safe for the environment:

    • MOECP approved, Central GTA facility
    • Quick and safe unloading of materials
    • Rigorous tracking, tracing, and testing system for contamination
    • 1,500+ tonnes of sand reclaimed per year
    • 100,000+ of gravel, sand and clay diverted from land fill
    • 19+ million litres of water are recycled and reused
    • Premium pipe bedding material available
    • 40% reduction in travel costs
    • 30% reduction in carbon emissions from reduced travel

From Coring to Restoration - Step by Step

Coring hole is asphalt

Coring

Keyhole coring allows vacuum excavation crews to access underground utilities quickly and safely, with minimal disruption to hard surfaces.

Backfill and Restoration

Our restoration work is supported by a diverse fleet and equipment including on-demand u-fill concrete trucks, stone slingers, and dump trucks.   


Hydro Excavation

Hydro excavation is the go-to approach for safe, fast, and damage-free soil removal using a combination of high-pressure water and high-flow vacuums while protecting underground infrastructure. 

Reinstatement of Test Hole

We reinstate the existing core using Utilibond to restore the road or sidewalk to its original state. Our keyhole coring process ensures that there is minimal disturbance to the structure and appearance of the work surface.
