Centerline provides high-resolution ground penetrating radar to identify buried features without the need for destructive testing or excavation. Our GPR solutions are essential for verifying the internal structure of concrete and locating buried assets that traditional electromagnetic tools cannot detect. By integrating GPR data with our 3D scanning and survey-grade GPS, we provide a digitized, georeferenced map of the site.

Our advanced ground penetrating radar technology is capable of more than just finding pipes; we specialize in void detection and material layer mapping to assess structural stability. Whether you are checking for washouts beneath a slab or measuring ice thickness for winter access roads, our equipment is tuned to the specific depth required for your environment. We utilize specialized sensors for both deep penetration and high-detail concrete analysis.
GPR technology is a critical safety tool for both renovation and greenfield construction. By using high-frequency antennas, we can peer through concrete slabs to map out reinforcement patterns and hidden utilities before any cutting or coring begins. This prevents costly damage to structural elements and ensures the safety of the crew on-site by avoiding electrical or high-pressure lines hidden within the structure.
On a larger scale, our low-frequency GPR systems are used for deep subsurface analysis, such as detecting underground storage tanks or soil voids. We can map out the different layers of the earth or ice thickness for winter road access. This versatility makes ground penetrating radar an essential component of a modern ground disturbance plan, providing a layer of “vision” that traditional locating tools simply cannot provide.
Yes. Unlike traditional line locators, GPR detects any change in material, making it the only reliable way to find plastic pipes or concrete conduits.
Absolutely. Unlike X-ray, GPR uses safe radio waves and does not require the site to be cleared. Work can continue as normal during the scan.
High-frequency is for high detail at shallow depths (rebar in a slab). Low-frequency is for deep penetration (finding a pipe 3 meters underground).
Yes. GPR provides accurate depth data, which is essential for engineers who need to know cover depth before digging or drilling.
We georeference our GPR findings so they can be placed exactly on your site plan or 3D model, giving you a permanent record of underground assets.
