Concrete Rebar GPR Scanning Services
Accurate Non-Destructive Testing with Ground Penetrating Radar (GPR)
What Is Concrete Rebar GPR?
Concrete Rebar GPR scanning uses Ground Penetrating Radar technology to accurately locate rebar, post-tension cables, conduits, and voids within concrete structures—without destructive coring or drilling.
This non-invasive method is essential for:
Construction planning
Structural assessments
Renovations & retrofits
Compliance with building codes & safety standards
Why Use GPR for Concrete Rebar Detection?
GPR scanning offers major advantages:
✅ Non-destructive: No damage to concrete or finishes
✅ Safe & fast: Scan areas in real-time with immediate results
✅ Accurate: Pinpoint exact depth & spacing of embedded objects
✅ Cost-effective: Avoid delays, utility hits, and safety hazards
✅ Required: For structural inspections and cutting approvals

🛑 Avoid These Common GPR Mistakes
Before cutting or coring concrete, ALWAYS scan to avoid:
Damaging structural steel or post-tension cables
Cutting live electrical conduits
Structural collapse from unsupported voids
Expensive repair costs
Worker injury and liability

FAQ Section
❓ Is GPR scanning safe for occupied buildings?
✅ Yes. GPR is completely non-invasive and emits no harmful radiation.
❓ How deep can GPR detect rebar?
✅ Up to 18–24 inches in concrete, depending on slab density and moisture content.
❓ Do you provide marked layouts on-site?
✅ Yes, we mark findings in real-time on the slab using chalk or paint.
Concrete GPR Detection Scan
Concrete GPR Cable PT Cable detection Scan Tampa, Sarasota, Clearwater, St. Petersburg and surrounding areas can locate rebar and post-tension cables within the concrete using Hilti PS 1000 state of the art technology. Reinforcing steel locations are marked directly on the concrete surface to ensure safe and efficient drilling that will preserve the integrity of the structure and reduce the need for repairs or patching. This helps our clients conduct core drilling without accidents, injuries or delay. Concrete PT Cable detection GPR Scan is also useful when preparing for a renovation that includes electrical outfitting, plumbing, fire protection services, drain installation and duct work.
Concrete GPR EMBEDDED ELECTRICAL SERVICES
When core drilling or saw cutting in commercial and industrial locations is needed, accurate detection of electrical conduits is essential for preventing safety risks, power outages and costly damages. Concrete GPR Scan for PT Cables Daytona provides two specific but different scanning services in this area: Elevated concrete slab scanning and concrete slab-on-grade locating. Elevated concrete slab scanning involves detecting embedded electrical conduits prior to core drilling a hole through the slab.
Concrete slab-on-grade locating – a concrete slab poured directly over dirt – involves scanning a trench line for conduits before conducting saw cutting and trenching to install a sanitary pipe, water line or something similar. [See diagram No. 2]
CONCRETE GPR ASSESSMENT
Also crucial in the Concrete Xray Scan Daytona imaging process is determining what’s in the concrete structure. This includes gauging the concrete thickness, what the rebar content is, its spacing and its elevation within the slab. This extensive, critical information helps our clients and their teams to understand the makeup of the concrete. we also can determine concrete covers over the rebar using state of the art equipment.
VOIDS DETECTION AND LOCATIONS
We can also locate voids – air gaps between the sub-grade, dirt and the concrete slab-on- grade – hidden below concrete or asphalt surfaces. This degradation occurs over time due to compaction, pipe ruptures or erosion but is often undetectable on the surface. EMA Concrete Xray ground penetrating radar can help our clients locate these areas and – most important – avoid collapses.
While GPR does not determine what type of object is being located project managers are experienced at using all available data in identifying the type of reinforcing steel or electrical conduit present.
The photo to the left shows a typical post tension cable mark out. Using GPR and other data, we are able to locate all of the reinforcing steel anomalies. We then mark the findings on the concrete and, based on the pattern, are quickly able to determine what each marking indicates. Most often, when something is on an angle through a square layout it will be a conduit. You will have a typical rebar pattern with 12-to-18 inch centers. Post tension cables tend to be spaced further apart, depending on the building’s design and whether they are banded or uniform tendons.
