Efficient Locating Solutions Guaranteed

Public Locate Coordination

We all understand how time consuming calling in public utility locates can be. At Landshark Locates we want to help reduce that stress on you. We will make the call to Ontario One Call for you and then manage collecting all the locates. We would keep in contact with you for any delays in collecting these locates. Once all the locates have been collected we would send a complete package to you. We can also help you to interpret the documentation you have been provided while in combination with our private locates. Public coordination is about saving you time and money while you work to complete and organize your projects.

Private Utility Locates

Landshark Locates provides private utility locate services using nondestructive locating methods. Our team of experienced locators have worked with public and private locates for more than 30 years combined. We understand how important utility locating is and we want to make sure you and everyone you work with can dig safely. Private utility locates are becoming more of a requirement than at any time before and we want to assure you we take it very seriously.

Please remember we are not a public utility locate service. For all excavation that takes place anywhere on your property from digging a small hole to major excavation you will always have to call Ontario One Call first.

Ontario One Call can identify many utilities that are owned by utility companies and municipalities. Landshark Locates can mark and identify utility services that are not covered by Ontario One Call. Utilities such as water, gas, electric, and communication lines may be run out to other buildings on site that are owned by the property owner. These are considered private and will not be marked by an Ontario One Call Request.

Subsurface Utility Engineering

We are able to perform all 4 levels of S.U.E. This process of engineering locate requires attention to detail in order to coordinate, locate and process all of the accumulated data. All collected data can be applied in CAD or a GIS compatible map.


This GPR unit is a large push behind unit. It is capable of scanning to depths of 20 feet. It can be used to help determine locations of Non-Metallic pipes, Electrical Cables, Storm and Sewer systems, UST’s, Septic system components, Utilities where tracer wire has failed, non-utility structures such as vaults, foundation walls and concrete pads.

Ground Penetrating Radar

This is a nondestructive geophysical method that uses radar pulses to image the subsurface. We are able to detect subsurface object, changes in material properties, voids and cracks in the right conditions.

Conquest Concrete Scanner

This GPR unit is used to image object in concrete prior to cutting or coring. It is able to locate conduits, post tension cables, rebar, wire mesh, and current carrying cables.

Public Utility Locate Validation

Do you ever question your public locates? When you get going on a long term project and your paint marks are faded or gone would you like them refreshed? As public locate companies move their expiry dates beyond the 30 day mark this becomes a more likely problem. Public locate companies do not help you with these things. Landshark Locates has skilled staff that have worked in the public locate sector. We can help you to understand your locates. Give us a chance to help review them and give you a better understanding of what you are looking at. Refreshing paint marks does not invalidate your locates. Most locate documentation will tell you it is your responsibility to keep them visible. If you need them repainted to keep your excavation crews happy just give us a call.

Indoor Locates

Working indoors is more complex than you may think. Many utilities are buried in the floor slabs in the area you may be working. Due to signal distortion not everything may locate accurately. It is always best to make a two step approach to working indoors and include GPR Concrete Scanning as a back-up. Concrete Scanning is great for avoiding Rebar as well as giving you an accurate scan verifying that no other existing or future utilities may be in your work area.

Trace Wire Conductivity Testing

Also known as locating or locator wire, tracer wire is a single conductor wire laid along pipes and other underground utilities during installation. Once installed, tracer wire helps workers find those assets later on. With our electromagnetic utility locating kit we can perform this verification process to ensure that your trace wire is conductive and will pass all inspections.

Flushing & CCTV Pipe Inspections

We can provide you Closed Circuit Television (CCTV) sewer and storm pipe main and lateral inspections to confirm the integrity of your utility lines. Through this process we can also provide accurate locating of the lines for excavation / engineering purposes. Detailed reports with an engineering stamp of approval, video and more.

Public vs Private

What is the difference between a private and public utility locate?

Public utilities are defined as those owned by large utility providers and include the mass distribution network of services such as sanitation, water, gas, electricity, and communication which connect us together. This includes connecting us to our cities, homes, and places of work. These utilities are considered publicly managed and owned up to a cut off point otherwise known as a “demarcation point”, which is usually situated on the outside of a house, building, property, or in maintenance and mechanical rooms. The cut off or “demarcation point” is usually identified by a metering system, transformer or vault. Utilities that continue after the demarcation point are owned by the property owner and considered private utilities. Private utilities may include:

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

Keeping Employees safe is very important when it comes to the working in the unknown. Its often very hard to understand the dangers of excavating and drilling when the hazards are buried beneath your feet. Imagine if you could easily see Ontario’s underground world, to expose how thousands of kilometers of unseen water, oil, electric, sewage and telecommunication infrastructure was keeping businesses and homes connected with data, power, heat, water, sanitation and communications. Ontario One Call can help to identify registered underground services in the area, except they do not identify and mark privately owned services. Landshark Locates will identify and mark the existence of private utilities such as water, gas, electrical, and communications on your work site to prevent injury to workers and damages caused by a utility hit.
