Ground Penetrating Radar (GPR) in Concrete Work: What We Find Beneath the Surface



Before any concrete cutting, coring, or drilling project begins, understanding what lies beneath the surface is critical. Embedded within concrete slabs are layers of steel reinforcement, post-tension cables, conduit, and occasionally voids or defects that are not visible to the naked eye. Striking any of these elements can cause costly damage, structural issues, or safety hazards. This is where Ground Penetrating Radar (GPR) comes into play.

At Kansas City Coring & Cutting, we use GPR technology to scan and map what is hidden inside concrete structures. This non-destructive method allows our technicians to work with precision and confidence while keeping your project safe, compliant, and on schedule.

What Is GPR and How Does It Work
Ground Penetrating Radar is a scanning technique that uses electromagnetic waves to detect and locate objects within a solid surface. The GPR unit emits radio waves into the concrete, which then reflect back to the receiver when they encounter materials with different densities such as metal, plastic, or voids.

Advanced software translates these reflections into visual data that show the position and depth of embedded items. This gives our operators a detailed map of what is inside the slab before any cutting or drilling begins.

Unlike older X-ray methods, GPR is faster, safer, and completely radiation-free. It can be used in occupied buildings and does not require shutdowns or evacuation.

What GPR Can Identify
GPR scanning can locate a wide range of materials and structural features including: • Rebar and mesh reinforcement
• Post-tension cables
• Electrical and plumbing conduit
• Voids, cracks, and delaminations
• Changes in slab thickness or density
By knowing exactly where these elements are, we eliminate guesswork and prevent costly mistakes.

Why GPR Matters in Concrete Work
Accuracy is everything in professional concrete cutting. Without proper scanning, even a small error can result in serious damage or injury. GPR gives contractors, engineers, and building owners the data they need to plan safely and confidently. It also reduces the risk of project delays and repair costs that come from accidental strikes. At Kansas City Coring & Cutting, our GPR-trained technicians integrate scanning directly into the workflow of coring, sawing, and demolition. Every scan helps ensure safety, compliance, and efficiency from start to finish.
