From private utility locates to ground penetrating radar.

Public Locate Coordination

It can be time-consuming to deal with public utility locates in Ontario, but the Landshark Locates team takes that burden off your shoulders for a streamlined locate process. We’ll call Ontario One Call, manage the collection of the locates, and keep you in the loop on any updates or potential delays. Once it’s fully organized, we send the complete package to you, offering interpretation support to help get your project off the ground.

Private Utility Locates

At Landshark Locates our team of expert locators will utilize safe, non-destructive locating methods to see what’s below the surface. We can combine our public Utility Coordination and private locate services to provide you with the best experience and give you the piece of mind you need to complete your dig safely.

Subsurface Utility Engineering

The Landshark Locates team offers all four levels of SUE, providing a custom analysis of your project’s subsurface environment. We expertly combine data from public locates, private locates, and ground penetrating radar (GPR), which can be used to create valuable deliverables like CAD drawings or GIS-compatible maps. These services minimizes excavation risks and streamlines project timelines.

Public Utility Locate Validation

Keeping track of public utility locates can be a challenge, especially on complex, long-term projects. If you’re questioning the validity of public locates, Landshark Locates can give you peace of mind. Whether your paint marks need freshed or public locates expire, our skilled staff can review and explain your locate services and documentation.

Interior Locates

Indoor locates requires a more careful and thorough approach as many utilities are buried in floor slabs and other materials that cause signal distortion. Our expert location team uses GPR concrete scanning as part of its two-pronged approach to avoid rebar, live hydro lines, conduits, and more to give you full peace of mind. and give you full peace of mind.

Trace Wire Conductivity Testing

Trace wires are often buried alongside utilities during installation to make it easier for future workers to find those assets. At Landshark Locates, we use an advanced electromagnetic locating kit to verify that your trace wires are conductive and will function properly during inspections. This proactive approach prevents delays and potential safety hazards.

Flushing & CCTV Drain Inspections

Landshark Locates offers comprehensive Closed-Circuit Television (CCTV) inspections for sewer and storm drain pipe to confirm the integrity of your utility services. This technology allows for a detailed visual assessment of the pipe’s interior, revealing potential problems like cracks, blockages, and deterioration, delivering you an inspection report, complete with video footage and an engineering stamp of approval.

Our Technologies

Ground Penetrating Radar

GPR is a cutting-edge, non-destructive geophysical technology that Landshark Locates uses to “look” underground. We can use this technology to send radar pulses into the ground, pinpointing the location of buried objects, changes in soil composition, and even voids or cracks in the right conditions.


The LMX-200 GPR is a non-destructive, push-behind unit that scans to depths of 20 feet to reveal hidden infrastructure like non-metallic pipes, electrical cables, storm and sewer systems, USTs, septic system components, utilities with failed tracer wires—we can even find non-utility service structures like vaults, foundation walls and concrete pads. 

Combining SUE with LMX-200 GPR data provides the most accurate picture of the subsurface, leading to better decision-making and cost savings

Concrete Scanning with GPR

Our Concrete Scanner is a specialized GPR unit designed to provide a clear image of objects inside concrete structures before cutting or coring. We use it to avoid any accidental damage to vital elements like conduits, post-tension cables, rebar, wire mesh, and current-carrying cables.

Public utilities are owned by large utility providers and include the mass distribution network of services such as sanitation, water, gas, electricity, and communication connecting us together. Knowing the difference between public and private utilities can help you ensure safe and efficient excavation projects. While public locates are crucial, they only cover public utilities up to the demarcation point, usually situated on the outside of a house, building, property, or in maintenance and mechanical rooms. 

Utilities beyond the demarcation point are private, including: 

  • Lights or signs on the property 
  • Buried storage tanks and lines, including fuel tanks & water discharge tanks
  • Electrical lines to sheds or secondary buildings 
  • Sewer and septic tanks, systems, and piping 
  • Security cameras 
  • Automatic gates or parking kiosks 
  • Gas lines to bbqs or pool heaters 

For a complete picture, you need both public and private utility locating services to ensure a smooth and safe project.
