Case Studies & Application Spotlights

This is a space for the Maverick Team to share case studies and application spotlights. These examples highlight different technologies and analysis software, creative solutions, and experiences. They are in a variety of formats and styles, and full of interesting tales and insights. Scroll down for titles and descriptions, and select one to look through.

  • Video Inspection Raft Development

    Maverick creates custom inspection solutions when there isn’t a commercially-available option that fits the application. This floating inspection platform was developed for inspection of industrial oily water sewers. An explosion-proof pan & tilt camera head was the primary instrument, but the system was designed for adding sonar and more. Ahead of the deadline and well under budget, Maverick’s R&D Team hit it out of the park!

  • Neighborhood Secondary Facility Locates

    This Application Spotlight focuses on a large-scale upgrade to utilities in an neighborhood involving horizontal directional drilling (HDD). This project required complete mapping of all underground facilities. Maverick was able to diligently and effectively work at a locating pace that allowed the replacement work to carry on unhindered without any damages to the private live facilities.

  • Ground Stability Investigation

    Maverick provides Ground-penetrating Radar services related to ground stability prior to activities such as critical crane lifts. This data collection typically involves positional systems such as a Robotic Total Station, analysis software, and a variety of presentation and reporting formats. Although real-time staking is appropriate for GPR tasks such as utility or storage tank locates, ground stability conditions are engineering and/or geophysical determinations. Maverick provides quality subsurface data gathering, analysis, and reporting quickly and diligently for geoscientists and other qualified professionals.

  • GPR for Concrete Ramp Repair

    A parkade ramp had been damaged by freeze/thaw cycles. Engineers were working on a solution, but they had no existing drawings or references to the ramp’s original design. Maverick mapped out the reinforcing steel with radar and provided a CAD model, allowing for repairs and return to service.

  • GPR for Bridge Girder Engineering

    A bridge built during the 1950s had been changed sometime later with a highway upgrade. There were no records of what sort of  reinforcing steel was in the bridge girders, so Maverick was brought in to quickly and cost-effectively provide radar mapping and create a CAD model of the rebar and stirrup placement. This information allowed engineers to assess the current capacity of the structure.

  • Peat Depth Investigation with GPR

    An ecological restoration company was interested in constructing ice roads on a forested work site
    for safe transport of personnel and heavy equipment. They needed to know the approximate depth to the peat
    layer in the area in order to use the least amount of water possible – a deeper peat layer will require more water
    to create an ice road. Maverick Inspection was able to conduct a peat depth investigation using low frequency
    GPR.

  • Sub-bottom Profiling with GPR

    In this application spotlight, Ground-penetrating Radar (GPR) was used to successfully investigate and map the sediment/mud layer at the bottom of a partially frozen lake. A unique approach was required for safe and diligent data gathering.

  • A Comparison of Technologies for Locating Abandoned Wells

    As a comparative case study, Maverick technicians selected a known well on an agricultural property in Northern Alberta. Wellheads or “Christmas Trees” were located visibly elsewhere on the property. However, there were no surface indications of the selected abandoned well, and a hand-held consumer GPS was used to provide an approximate starting point for data collection grids. Ground-penetrating Radar (GPR), Electromagnetic Conductivity Profiling, and Magnetic Gradiometry were all used to compare their relative effectiveness for locating abandoned wells.

  • Long-Range Video Inspection in Remote Locations

    In autumn of 2015, a provincial energy corporation was planning to pull high voltage electrical cables capable of producing 900 MW through six carbon steel casings. These casings crossed the Strait of Belle Isle underneath a section of ocean between Newfoundland and Labrador. Maverick was chosen to inspect these casings to confirm that there would not be any objects, rough edges, or other defects which could damage the high voltage cables or casing coatings as they travelled through.

  • Critical Crane Lift Scans with GPR

    A 65 tonne crane lift was planned to remove a vessel from an existing unit in an industrial facility. This spotlight discusses the use of Ground-penetrating radar (GPR) was prior to set-up to provide valuable subsurface information.

  • Ground Saturation Plumes with GPR

    Ground-penetrating Radar (GPR) is not the preferred technology for mapping saturation plumes. In this case, however, steel-reinforced concrete, above ground metal structures, and other factors made it the only viable choice. Read how Maverick technicians successfully mapped out areas of saturation.

  • Laser Profiling of Pipeline Deformations

    Read about Laser Pipe Profiling’s use to determine the deformation of a pipeline roadway crossing in Northern Alberta.
