If you’ve searched for ground penetrating radar prices, you’ve probably noticed most companies don’t list one. That’s because GPR pricing depends on the job in front of the technician, not a number on a website. A small concrete scan before an anchor install and a full utility locate across a commercial site are two different projects with two different price tags.
At C&M Subsurface, pricing is built around the actual scope of work rather than a flat menu rate. Here’s what goes into that number and why a quote will always serve you better than a generic price list.

Most GPR providers bill by time on site, either hourly or by the day, with a minimum charge to get a technician out to your location. That minimum covers travel, setup, and the base time it takes to run a proper scan, even on a small job. A five-minute scan and a two-hour scan both require the same drive out, the same equipment setup, and the same review of findings.
From there, pricing typically scales up through a half-day rate and a full-day rate for larger projects. C&M structures quotes around this same logic. Job length, not square footage alone, is usually the better predictor of cost, since a small area with dense rebar can take longer to interpret than a larger, simpler slab.
The kind of scan you need has a direct effect on price. GPR concrete scanning services to locate rebar, post-tension cables, or voids use higher-frequency antennas and tend to move faster once the technician is set up, since the target depth is usually under two feet.
A utility locate covers more ground and often calls for both GPR and electromagnetic equipment working together. GPR can detect both metallic and non-metallic lines, including plastic conduit, but an ambiguous return still needs a second method to confirm what it actually is. EM locators can’t see non-metallic lines at all, but they trace the exact path and depth of a live metallic conductor with more certainty than GPR alone. Running both together means one method can confirm what the other only suggests.
Cemetery GPR scanning is its own category. These projects usually cover larger, less defined areas and require careful documentation of soil disturbances, which takes longer than a straightforward concrete scan.
X-ray was once the standard method for concrete scanning before GPR became the industry preference. See our breakdown of comparing GPR and X-ray methods for how the two compare on cost and speed.
Larger sites take more time, but size isn’t the only variable. Dense rebar, congested utility corridors, or a site with multiple obstructions all slow down a scan and require more careful interpretation. Site access changes the timeline too. A tight indoor mechanical room, a vertical wall, or a job that requires scanning around active equipment takes longer than an open, accessible slab.
Ground and material conditions play a role as well. Wet clay soil absorbs radar energy and can force a technician to rescan an area to get a usable read. Projects tied to directional drilling often involve exactly this kind of variable soil, which is one reason those jobs get quoted individually rather than off a standard rate.
C&M Subsurface started in College Station and is now in Houston and DFW, serving areas across the state. For projects within those areas, travel is usually built into the standard rate. For jobs farther out, mileage and travel time get added to the quote, and a project that requires an overnight stay carries additional costs.
This is one of the more overlooked factors in GPR pricing. Two identical scans in two different cities can carry different price tags simply because of the distance a crew has to cover to get there.
What you need at the end of the scan affects the price as much as the scan itself. On-site markings, where rebar, cables, or utility lines are marked directly on the surface, are usually the fastest and most affordable option since the crew can hand off findings before leaving the site.
A written report with in-depth information and imagery takes longer to prepare, since it involves reviewing and organizing the data after the field work is done. Projects that call for 3D imaging add another layer of processing time, since the models need to be built from the collected data rather than marked in real time. C&M’s GPR concrete scanning services can be scoped for markings only, a full report, or both, depending on what the project actually requires.
Any company that lists a flat GPR price for every job is either quoting only the smallest possible scope or leaving out variables that will show up on the invoice later. Between service type, site conditions, travel, and deliverables, two projects rarely look alike.
A flat rate that looks too good is worth a second look. A rushed scan or a technician who skips a proper interpretation step can miss something, and the cost of a missed utility line or a struck post-tension cable is far higher than the price of the scan itself.
C&M Subsurface quotes every job individually based on scope, and proposals typically go out the same day a project is discussed. As a Texas-based, Aggie-owned company, our team works directly with clients instead of routing calls through layers of scheduling, and that direct contact is a big part of why turnaround stays fast. Getting the right GPR equipment on site starts with an honest conversation about scope, not a guess pulled from a price list.
Whether you need a concrete scan before coring, a private utility locate before excavation, or a cemetery GPR survey, C&M Subsurface can walk through your project and put together a quote based on what the job actually requires. Call (979) 300-5186 or contact us online to describe your site, and we will identify the right scope and equipment for the work.
It depends on the type of scan, the size and complexity of the site, and what deliverables you need. We charge a minimum for smaller jobs and scale up to half-day or full-day rates for larger projects, so the best way to get an accurate number is to walk us through your scope.
We bill by time on site, with a minimum charge for smaller jobs and day rates for larger ones. The final price still comes down to the specifics of your project, including site conditions and whether you need markings, a report, or both.
Yes. Projects outside our normal coverage area usually carry additional mileage or travel charges, and jobs that require an overnight stay may include per diem or hotel costs. If your project falls within our core service area across Texas, travel typically isn’t a factor in your quote.
