When a core drill hits a post-tension cable or a saw cut damages a buried conduit, the job stops. What started as a straightforward project becomes an expensive problem with liability questions attached to it. The work inside a concrete slab is invisible until something forces it to the surface, and by then the cost of not knowing is already set.
Ground Penetrating Radar (GPR) concrete scanning gives contractors, engineers, and renovation crews across Texas the subsurface imaging data they need before any cutting, coring, or drilling begins. C&M Subsurface provides professional GPR concrete scanning services with accurate results, fast response times, and a team that understands what’s at stake when you’re working in concrete.
Understanding how GPR technology works helps explain why it’s the preferred method for concrete scanning. Ground penetrating radar emits high-frequency radio waves into a concrete structure and measures how those waves reflect back when they encounter changes in density. Rebar, post-tension cables, conduits, voids, and other embedded features all produce distinct return signals, which our technicians read and interpret on-site in real time. The data is captured as the GPR antenna passes over the concrete surface, building a clear picture of what’s below without any drilling, cutting, or disruption.
When weighing GPR compared to X-ray scanning, the practical differences are significant. X-ray requires access to both sides of the structure, involves radiation hazards, and requires clearing all personnel from the work area. It’s slower, more expensive to coordinate, and creates real scheduling friction on active job sites. GPR concrete scanning requires access to only one side of the surface, involves no radiation, and delivers results while you’re still standing on-site. For most commercial and construction applications in Texas, it’s simply the better tool.
GPR detects rebar depth, spacing, and layout with precision. Knowing exactly where reinforcement sits lets crews plan saw cuts and core drill locations without risking structural damage or liability on the job.
Embedded grade beams need to be identified before any cutting or coring begins. GPR locates their position and depth so crews can work around them without compromising structural integrity.
PT cables are under extreme tension. If one is struck during a cut or core drill, the results can be dangerous and the structural consequences are serious. GPR locates them accurately so your team can mark safe work zones before any tool touches the slab.
Electrical conduits and other embedded systems are common, often undocumented, and easy to damage. Scanning identifies their location and depth before penetration work begins.
Subsurface voids compromise structural stability and aren't visible from the surface. Catching them early gives your team the chance to assess the situation before work uncovers a problem that stops the project.
Accurate thickness measurements are possible without surface damage, supporting structural assessments, anchor installations, and renovation planning where slab depth affects how the work gets done.
GPR concrete scanning is used across a wide range of industries and project types. If your work involves cutting, coring, drilling, or modifying concrete in any way, a scan before you start is the right call.
Cutting, coring, drilling, or structurally modifying an existing slab carries real risk without knowing what's inside first.
Accurate subsurface data is essential when modifying load paths, evaluating existing structures, or planning work in buildings without original construction documents.
Existing concrete of unknown composition is the norm on renovation and demolition jobs. A concrete scan removes the guesswork before work begins.
Anchor installations, utility penetrations, and ongoing maintenance work in concrete structures all benefit from knowing what's embedded in the slab.
C&M Subsurface mobilizes quickly across Texas’s major construction markets. Our GPR services in Houston support one of the most active construction regions in the state, from large commercial builds to medical and industrial facilities. Our GPR services in Dallas serve contractors and engineers throughout the metroplex, working on everything from high-rises to retail build-outs. And our GPR services in Fort Worth bring the same fast response times and field expertise to the projects moving through that market.
Beyond the major metros, we also serve Austin, College Station, and surrounding areas. As a Texas-based, Aggie-owned and operated company, we work directly with our clients from the first call to the final deliverable. We’re not a national firm that treats you like a number. When it comes to the cost of GPR scanning, our pricing is competitive, and we’ll provide a clear proposal quickly so you know exactly what to expect before we’re on-site.
As a Texas-based, Aggie-owned and operated company, we work directly with our clients from the first call to the final deliverable. We’re not a national firm that treats you like a number. Our pricing is competitive, we personalize our approach to what each project actually needs, and if something doesn’t look right after a scan, we’ll come back and re-survey at no additional cost.
Every concrete scanning job at C&M Subsurface follows the same straightforward process. You contact us with your project details, and we respond quickly with a clear proposal. Once scheduled, our certified GPR technician arrives on-site with advanced concrete scanning equipment and gets to work. As the scan progresses, embedded features are identified and marked directly on the concrete surface in real time, so your crew can see results immediately and adjust plans on the spot.
After the scan, our technician reviews the findings with your team on-site. Detailed reporting and deliverables are available based on what your project actually requires – we tailor what we provide to what’s useful to you, not a standard output that may or may not fit what you need.
If your project in Texas involves cutting, coring, drilling, or any modification to existing concrete, don’t start without knowing what’s inside the slab. C&M Subsurface provides accurate, reliable GPR concrete scanning services with the fast response times and competitive pricing your project demands.
