Sub Surface Investigation

Maverick Inspection Ltd. refers to sub surface investigation as the process of examining and assessing what lies beneath the surface of the ground, typically to locate and identify underground utilities or objects. This investigation involves the use of various technologies and techniques, including ground penetrating radar (GPR), electromagnetic locating, and magnetometry.

Ground Penetrating Radar

Ground penetrating radar (GPR) is a geotechnical method that uses radar pulses to create an image of subsurface structures and objects. It is commonly employed in utility locating to identify underground utilities such as pipes, cables, and conduits. GPR sends electromagnetic waves into the ground, and when these waves encounter changes in material composition or buried objects, they reflect back to the surface. By analyzing the reflected signals, a trained operator can determine the presence and location of subsurface utilities.

Electromagnetic Locating

Electromagnetic locating is another technique used for utility locating. It involves the use of electromagnetic signals to locate buried metallic objects, such as utility pipes and cables. This method relies on the principle that buried metallic objects create magnetic fields that can be detected and traced using specialized equipment. By moving the electromagnetic locator along the ground surface, the operator can trace the path of the buried utilities and mark their locations.

Push Reels and Sondes

Pushreels are used to deliver sondes in piping and sub surface utility conduits. Sondes emit an electromagnetic signal, allowing an electromagnetic detector to pick up the signal through areas that are difficult to detect or deeply buried utilities.

Geomatics Mapping and Modeling

Whether you require detailed topographic surveys, 3D modeling, orthophoto production, vegetation analysis, or any other geomatics-related services, Maverick Inspection Ltd. is your trusted partner. We are committed to leveraging the latest technologies and industry best practices to provide reliable, cost-effective, and innovative geospatial solutions that empower our clients to make informed decisions and achieve their project goals.


    Concrete basins, sumps, surge tanks and infrastructure below ground can be inspected using remote video inspection technologies including crawlers and internal drones/UAVs. Maverick range from the provision of CSA Class 1 Div 1 ATEX rated equipment for explosive environments to internal drones equipped with 4k cameras. These technologies can be used to reduce manned inspections and de-risk infrastructure inspection.

    Magnetometry is a geophysical method used to detect and map variations in the Earth’s magnetic field. In utility locating, magnetometry can be utilized to identify subsurface metallic objects, such as buried tanks or metallic infrastructure. Magnetometers measure the magnetic field strength, and any deviations from the background field can indicate the presence of subsurface objects. This method is particularly useful for detecting large metallic structures or anomalies
