GPR Concrete Scanning Experts in Ottawa & GTA

Building Safely with Decades of Concrete Scanning Experience

At Titan Scanning, we pride ourselves on making construction safer and smarter. Based in Ottawa (with a branch serving the Greater Toronto Area), our team brings combined decades of experience in concrete cutting, coring, and scanning to every project. We specialize in advanced Ground Penetrating Radar (GPR) scanning for concrete, a non-destructive method that lets contractors and engineers “see” inside concrete structures before any cutting or drilling happens. By choosing our concrete scanning services in Ottawa or the GTA, clients avoid costly mistakes, reduce downtime, and ensure compliance with safety regulations. We’ve had the privilege to work on high-profile structures – including scans at Parliament Hill and the CN Tower – and hundreds of other buildings across Southern Ontario, so you can trust that we’ve truly seen it all.

Professional results, fast: Our GPR experts know how to get accurate data in the field quickly, which means digital scan reports are often ready before we leave your site. No waiting around for postprocessing – you get the answers you need on the spot. It’s all part of our commitment to the quality you expect and the service you deserve. (And yes, you can always call us for a free quote to see how we can help on your next project!)

What is GPR and Why Do Contractors & Engineers Use It?

Ground Penetrating Radar (GPR) is a proven scanning technology that uses radar waves to image what’s inside concrete. In practice, a technician passes a GPR scanner over the concrete surface to detect materials or voids hidden within. The radar emits electromagnetic pulses into the concrete; when the waves hit something like metal or a change in material, they bounce back. By reading these signals, GPR can map out what lies beneath the surface without any drilling or damage.

For construction contractors, GPR scanning is a lifesaver. It locates embedded hazards before you cut or core, so you don’t accidentally slice into a live electrical conduit, sever post-tension cables, or hit loadbearing rebar. Accidentally cutting these hidden elements can create dangerous situations and costly delays. Using GPR greatly reduces these risks, ensuring a safer and more efficient job site. In fact, local building codes and safety standards increasingly demand scanning before altering concrete, and for good reason – it prevents accidents and keeps projects on schedule.

For engineers and architects, GPR provides critical insights that inform design and structural assessments. Scans allow engineers to map out the internal structure of a slab or wall – revealing where the rebar, beams, and other elements are – which helps in evaluating a structure’s integrity or planning retrofits. GPR data can even verify if construction work meets specifications and safety codes. In short, whether you’re a site superintendent or a structural engineer, concrete scanning with GPR is an indispensable tool to “X-ray” the concrete and plan with confidence.

Key things a concrete GPR scan can detect:

  • Rebar and Reinforcing Steel: The mesh or rebar grid that strengthens concrete slabs and columns. Knowing rebar layout is crucial for both structural analysis and avoiding blade strikes during cutting.

  • Electrical Conduits & Utility Lines: Pipes or ducts carrying electrical wires, plumbing, or communications lines embedded in or beneath the concrete. Cutting into an energized conduit can be catastrophic, so finding them first is vital for worker safety.

  • Post-Tension Cables: High-tension steel cables in many modern slabs. These must never be cut accidentally – a severed post-tension cable can whip out of concrete and cause serious injury. GPR spots their position so they stay intact.

  • Void Spaces or Honeycombing: GPR can identify voids or air pockets inside a slab. This helps engineers assess structural integrity and contractors avoid areas that might crumble or cause issues when cored.

  • Underground Utilities and Pipes: Not just within the concrete – GPR is also used on concrete floors or paved areas to locate water pipes, gas lines, and sewer lines running underneath. Before you sawcut a floor or excavate, you want to know what utilities are below to prevent outages or floods. By detecting all these features with one scan, GPR gives a complete picture of the subsurface. Contractors can proceed with cutting or coring confidently, knowing exactly what’s (not) in their way. And engineers get the data they need to make informed decisions about modifications or safety. It’s safety, quality, and efficiency bundled into one service – which is why concrete scanning is now considered essential for any significant project.

How Does Ground Penetrating Radar Scanning Work?

A GPR concrete scan in action – our technician has marked the floor to show rebar locations and other findings detected by the scanner. This non-destructive process reveals the layout inside the slab so that cutting or drilling can be planned safely and accurately.

Ground Penetrating Radar might sound like something out of science fiction, but it’s actually a straightforward and proven technology. Here’s how a typical concrete scan works on your site:

  • Setup: We use a portable GPR scanning unit (it looks a bit like a small cart or sled) that we roll over the concrete surface. No need to evacuate the area – unlike X-ray, GPR uses safe radio waves, so work can often continue around us.

  • Scanning: The GPR device sends quick pulses of radar into the concrete. When these waves encounter an embedded object or a change in material (say, the interface between solid concrete and an air void, or concrete and metal), the waves reflect back to the device’s antenna. We systematically move across the area in a grid pattern to cover the whole scan zone.

  • Real-time Analysis: As we scan, the GPR machine generates a visual readout of the subsurface. This appears as radar signal lines on a screen, which our trained technician interprets on the fly. Metal objects like rebar or conduits produce strong, recognizable signals, while voids, conduits or softer materials create different signatures. Because our team has scanned countless slabs, we can quickly distinguish these patterns. We often mark the concrete surface with paint, marker, non-permanent chalk or tape to indicate where things are (as in the photo above), so you get an immediate visual map.

  • Findings: The result of a GPR scan is essentially an accurate map of what’s inside your concrete. We identify all the critical elements – rebar spacing, depth of conduits, location of any anomalies – and communicate that to you right away. If needed, we can also save the data for a formal digital report. But in most cases, you’ll have the crucial information before we even pack up our gear. That means your cutting or coring team can proceed without delay.

One huge advantage of GPR scanning is that it’s truly non-destructive. There’s no drilling, no need to cut test holes, and no radiation. The concrete remains completely intact. We’ve essentially peeked inside it with advanced radar and left the site just as we found it – only now you have the knowledge of what lies beneath. This makes GPR the preferred method for scanning concrete in almost all scenarios (X-ray scanning is an alternative but requires evacuating the area and using hazardous materials, so it’s rarely practical on active job sites).
