multiVIEW Locates helped pioneer concrete scanning and concrete imaging techniques in Ontario using environmentally safe Ground Penetrating Radar (GPR).
Today, our GPR applications are vast, including concrete scanning for bridges, roads, buildings, and other structures. We’ve worked on thousands of projects across Ontario for customers that include design engineers, plumbers, electricians, property developers, architects, and construction contractors.

When a stretch of road has recently been repaved, it may appear to be in good condition but the subsurface conditions might be poor. GPR has the ability to detect areas where asphalt is unusually thick or thin and this information can be factored into the design process.
Ground Penetrating Radar – the safe way to scan
GPR is a non-invasive, non-destructive technique that is extremely effective at locating embedded features before you saw, drill or break concrete.
- Doesn’t emit harmful radiation, which means that no clearance area is required and there is no disruption to business continuity.
- It’s effective over a range of finishes including rubber membranes, granite, marble, carpet, and asphalt, meaning that these materials don’t need to be cut or removed before scanning occurs.
- Access is only required to a single side of the concrete slab, making it an ideal technique for slab-on-grade projects.
Concrete Scanning & Imaging services include:
- Embedded Conduit / Utility Detection
- Rebar / Wire Mesh Locating
- Concrete Slab Thickness Measuring
- Bridge Deck Deterioration Analysis (ASTM D6087-08)
- Void Detection
- Project Management
High impact reports
Once the data is captured, we will extract valuable insights and provide you with an in-depth analysis report that can offer one or more modes of acquisition, depending on project needs and customer’s desire.
- Mark surface of scanned project area with temporary paint or chalk lines to identify subsurface conduits and pipes using the industry standard colour code associated with the utility infrastructure
- Photo Report identifying features, data points, and anomalies
- Line Scan; section view data offered as a 2D image, colour coded and annotated for interpretation
- Grid Scan; a collection of grid data that offers a more intuitive 2D image approach using colour contours maps to illustrate key findings
- 3D Visualization; provides better insights to data analysis and interpretation (e.g. ability to visualize direction and overlay of rebar)
