San Diego GPR Services for Reliable Subsurface Mapping and Damage Prevention
Util-Locate utilizes the latest equipment, cutting-edge technologies, and over 13 years of experience and expertise to produce cost-effective, fast, efficient, and accurate GPR survey solutions.
Util-Locate can determine the most suitable survey methodology based on clients' specifications and is proud to be able to provide onsite real-time data with 3D imaging capabilities.
Ground Penetrating Radar (GPR) is a non-intrusive surveying technique used to locate utilities, rebar, conduits, voids, and other features below the surface.
GPR uses pulses of energy to image the subsurface. An integrated computer records the strength and time required for the return of reflected signals and stores this data on digital media. Differences occur in natural and man-made materials such as geological structures, pipes, and wire.
As a non-destructive and dynamic survey technique, GPR can be applied on a variety of surfaces, including rock, soil, ice, fresh water, pavements, and concrete structures.
San Diego construction, utility, and facility teams call Util-Locate when one wrong cut can shut down a project.
Our San Diego GPR services combine ground penetrating radar with full utility locating to map what sits beneath roads, slabs, parking lots, and concrete structures before excavation begins.
Since 2001, our certified technicians have completed thousands of San Diego GPR scanning jobs across military bases, hospitals, schools, and commercial sites. The result is fewer surprises, fewer line strikes, and fewer delays.

Ground Penetrating Radar Built for San Diego's Underground Network
San Diego's underground network includes aging gas lines, fiber optic cables, water and sewer mains, and post-tension cables in modern slab construction. Our San Diego GPR locator equipment uses high-frequency radar pulses to map both metallic and non-metallic targets, including PVC pipes, fiber-optic cables, voids, and underground storage tanks. Ground penetrating radar gives our crews a non-invasive investigation method that protects existing utility lines and avoids the cost of trial digging. We pair GPR with electromagnetic locating, vacuum potholing, underground utility locating, and CAD-grade utility mapping so every report reflects field-verified data, not guesses.
Complete GPR and Utility Locating Services from Util-Locate
We deliver every subsurface service through one provider, which keeps timelines tight and accountability clear. Each San Diego ground penetrating radar service is performed by certified utility locators using advanced equipment and documented to ASCE C-A 38-02 industry standards. Our service set covers underground utilities and concrete-embedded targets:
- Underground utility locating: Our utility locators identify electrical, gas, water, sewer, and communication utility lines up to 13 feet deep using electromagnetic sensors paired with GPR.
- GPR scanning, San Diego, CA: High-resolution ground penetrating radar systems detect subsurface utilities, voids, rebar, and post-tension cables before any cut, core, or drill.
- Concrete and surface scanning: GPR utility locating in San Diego extends into concrete structures, slabs, and walls to protect tendons, conduits, and reinforcement.
- Utility mapping and CAD services. We deliver CAD drawings, KML files, and PDF reports of subsurface utilities and buried objects, suitable for design, construction, and as-built records.
- Vacuum excavation and potholing: When visual proof is needed, non-intrusive surveying with a hydro vacuum exposes the utility without disturbing the surrounding soil.
- CCTV pipe inspection and leak detection: Robotic cameras and acoustic sensors locate cracks, joint failures, and leaks across pressurized and gravity lines.
- 24/7 emergency utility detection. Underground GPR scanning in San Diego is available after hours for utility strikes and active leaks.
97% Accuracy Backed by Two Decades of Damage Prevention Work
Util-Locate has operated since 2001 and completes around 11,187 locates each year across Southern California and Arizona. Our utility locating service holds a 97% accuracy rate, supported by survey-grade GPS, robotic total stations, and ground penetrating radar systems calibrated for varied soil and saturation conditions. Every San Diego GPR survey is performed under ASCE C-A 38-02 standards, the same framework civil engineers reference for subsurface utility engineering. That combination of geology and geophysics expertise, plus documented procedure, is what keeps subsurface damage prevention consistent across thousands of utility projects each year.
Industries and Project Types We Support Across San Diego County
Our San Diego GPR services support general contractors, civil engineers, public utilities, government agencies, and private property owners. Past and current work covers airports, military installations, university campuses, hospitals, hotels, theme parks, retail centers, and residential developments. Util-Locate has served Camp Pendleton, LAX, Kaiser Permanente, USC, UC Irvine, Disneyland, and Southern California Edison, among others, and we apply the same documentation standards to a backyard fence project as we do to a runway expansion. If your San Diego site involves digging, drilling, or coring near subsurface structures, our utility detection workflow fits.

For more details on our utility locating services, GPR surveys, and subsurface solutions, visit our full FAQs page. The questions below cover the points San Diego clients ask most often.
San Diego GPR services cover subsurface scanning for both metallic and non-metallic targets, which standard electromagnetic utility locating cannot detect alone. Ground penetrating radar reaches PVC pipes, fiber optic cables, post-tension cables, voids, and underground storage tanks, then maps them to CAD or KML for design, construction, and as-built records.
Detection depth depends on soil conductivity and moisture, which vary across San Diego from sandy coastal sites to clay-heavy inland areas. In most San Diego conditions, our advanced equipment reliably detects buried objects at depths between 6 and 13 feet for utility locating, and up to 18 inches inside concrete structures and post-tension cables.
Yes. Our 24/7 emergency utility detection line is staffed for strikes, active gas leaks, water main failures, and other urgent situations. A certified utility locator can be dispatched after hours to perform underground GPR scanning in San Diego and document the issue for repair crews and insurance.
Each San Diego GPR survey produces marked field locations, a CAD drawing, a Google Earth KML file, and a PDF report compliant with ASCE C-A 38-02 industry standards. Reports identify utility lines, subsurface utilities, and buried objects with accuracy levels noted, so engineers and contractors can plan with confidence.
Yes. Non-intrusive surveying with GPR is the standard approach for any cut, core, or drill into concrete structures. Our San Diego GPR scanning reliably locates rebar, conduits, post-tension cables, and voids, which protects the structural integrity of the slab and avoids cutting into utility lines embedded in the pour.
