    C Below can provide subsurface imaging and utility mapping to provide our client with a record of all indications found. Indications found in concrete or masonry structures by use of Ground Penetrating Radar (GPR) can be provided in a 3-Dimensional image that provides the best interpretation of data and an easy to read picture of the subsurface conditions.




    Utility locations can be plotted on a client provided site drawing in clear, easy to read detail. Each utility is labeled and color coded just like the indications marked in the field.

    With the use of the most current survey technology available, C Below can achieve an accuracy level of within 3mm.



  • Mapping
  • In addition to 36" x 24" prints, our drawings can also be saved in PDF format for simple distribution and viewing. Our detailed drawings can be used to provide designers and contractors with an overview of what to expect when performing site work.

    When radiography is used, radiographs are provided to the client for each shot taken. The photos include a report detailing the location of each shot and any pertinent data the client may need to make design or construction decisions, such as size and spacing of indications found.

What does the mapping look like and how accurate is it?

Computer-aided design (CAD) is the use of computer technology for the design of objects, real or virtual. C Below uses the latest GNSS technology to insure the industries most accurate drawings. After all lines are located and clearly marked, our surveying party plots the finding to an accuracy of with in 3 mm. Our drawings can be provided with varying levels of detail per the clients instructions. We provide hard copies on 24” x 36” color prints, along with a CD of the electronic files. We also offer FTP access to clients with multiple locations that may benefit from a centralized location for all drawings, images or videos related to CCTV Inspection.
