Why GPR Investigations are Essential Before Concrete Cutting

Conducting a GPR investigation before starting any concrete cutting project in Marietta, GA, is crucial for ensuring safety and efficiency. GPR scanning allows Cobra Southeast to detect hidden elements like electrical conduits, rebar, and post-tension cables within the concrete. By identifying these subsurface features, we help prevent accidental damage to critical infrastructure, reducing the risk of costly repairs and project delays. GPR investigations also provide valuable insights that allow for more precise planning and execution of your construction activities.

  • Safety

    GPR helps identify and locate any hidden utilities or objects beneath the concrete surface, such as electrical cables, gas lines, water pipes, or rebar. Cutting into these utilities can cause serious accidents, injuries, or damage to infrastructure. GPR allows for the detection and avoidance of these hazards, ensuring the safety of workers and preventing costly repairs.

  • Cost-Savings

    Accidentally cutting into utilities or objects can result in expensive repairs, delays, and legal liabilities. By using GPR to locate and mark the position of these utilities before cutting, potential damages can be avoided, saving both time and money.


  • Efficiency

     GPR provides real-time, non-destructive scanning of the subsurface, allowing for quick and accurate identification of potential obstacles. This helps contractors plan their cutting or excavation activities more efficiently, reducing downtime and improving project timelines.

  • Accuracy

    GPR can provide detailed information about the depth, size, and location of objects beneath the concrete surface. This allows contractors to make informed decisions about the best approach for cutting or excavating, minimizing the risk of errors or damage.

  • Compliance

     In many job sites, it is a legal requirement to use GPR or similar technologies to locate utilities before cutting or excavating. By following these regulations, contractors can avoid penalties, legal issues, and damage claims.

A Ground Penetrating Radar (GPR) survey is conducted using the following steps:

  • Equipment Setup

    The GPR system consists of a control unit and a radar antenna. The antenna is connected to the control unit, and the system is powered on.

  • Calibration

    Before starting the survey, the GPR system is calibrated to ensure accurate data collection. This involves setting the appropriate parameters such as dielectric constant, time and linear gain, and background removal depth.


  • Data Collection

    The radar antenna is placed on the ground and moved along the survey area in a systematic pattern. The antenna emits electromagnetic waves into the ground, and the reflected signals are recorded by the system. The data is collected in the form of radargrams, which are cross-sectional images of the subsurface.

  • Data Interpretation

    The collected data is analyzed and interpreted to identify subsurface features and anomalies. This involves examining the amplitude, shape, and depth of the reflections to determine the presence of underground objects or structures.

  • Mapping and Reporting

    The interpreted data is used to create field markings, showing the location and characteristics of the detected features. A report is generated, summarizing the findings and providing recommendations if necessary.

It is important to note that conducting a GPR survey requires expertise in data interpretation and knowledge of the subsurface conditions. Professional geophysicists or surveyors are typically involved in performing and analyzing GPR surveys.

Applications of GPR Concrete Scanning

GPR concrete scanning is an invaluable tool for a wide range of construction and renovation projects in Marietta, GA. At Cobra Southeast, we utilize this technology for several critical applications:

  • Utility Locating

    Accurately identify the position and depth of underground utilities, such as water lines, gas pipes, and electrical conduits, before cutting or drilling. This prevents damage to essential services, ensuring safety and avoiding costly repairs.

  • Rebar Detection

    Our GPR scans precisely map out the rebar within concrete slabs, walls, and floors. This is crucial for projects involving drilling, coring, or sawing, as it helps avoid cutting through structural reinforcements that could weaken the integrity of the building.

  • Void Detection

    Detecting voids or air pockets within concrete is essential for maintaining the structural stability of your project. GPR scans can identify these hidden gaps, which could compromise the foundation or other critical areas if left unchecked.

  • Post-Tension Cable Identification

    In structures with post-tensioned concrete, cutting through cables can be dangerous and damaging. GPR scanning allows us to pinpoint the exact location of these cables, ensuring that they are not compromised during cutting or coring operations.

By leveraging GPR technology, Cobra Southeast provides you with a comprehensive understanding of what lies beneath the surface, enabling safer, more efficient project planning and execution.

Contact Us

  • How deep can you see into concrete?

    The antennas Cobra use can penetrate up to 18″ thick concrete on applications with both sides accessible by up to 36″.

  • Is GPR Safe?

    Absolutely. Much like ultrasound, the signals are very high frequency not unlike those of Wi-Fi or cellphones. The equipment is FCC approved and deemed safe for the operator and all persons nearby. It is much safer AND cost effective than X-ray inspections.

  • How Accurate Is GPR?

    On an average 6″ – 8″ slab on grade inspection, targets were located within 1/4″ of their markings laterally and within 1/4″ of their depth estimations. Markings are made as bold and clear as possible unless finished surfaces do not allow. If that is the case, other means are used such as masking tape, pencil, etc.

  • Why is GPR scanning important in construction projects?

    GPR scanning is crucial for locating rebar, post-tension cables, and utilities within concrete, helping to prevent accidental damage, ensure safety, and save time and money during construction.


  • Is GPR scanning effective for assessing the condition of concrete structures?

    Yes, GPR can identify voids, delamination, cracks, and other structural defects, aiding in condition assessment and maintenance planning.

  • How long does a typical GPR scanning project take?

    The duration of a GPR scanning project depends on the size and complexity of the structure. Small projects may take a few hours, while larger ones could take several days.
