Concrete Scanning & Imaging

Stop Cutting Through Conduits & Reinforcement


Trinity Subsurface Engineering uses a combination of electromagnetic and concrete imaging radar equipment to perform surface geophysical services on concrete surfaces such as:

  1. Slabs
  2. Floors
  3. Walls
  4. Columns

Using this combination of equipment allows Trinity Subsurface, LLC field employees to analyze objects embedded within and directly below the concrete surface. 

Clients utilize our concrete scanning & imaging surfaces to reduce the risk associated with core drilling and trench cutting inside of an existing building where Call 811 won’t mark-out. Our services are also utilized to find existing utilities, such as sanitary sewer lines, for new tie-ins. 

Unlike concrete x-ray services, the use of concrete imaging radar is not only much safer to perform, but it is a service that can be performed much faster as well, making it more cost effective for the average construction or engineering project.

Our concrete imaging radar service is a combination of an electromagnetic and concrete penetrating radar survey. Our first step is to locate all know utilities within and below a concrete slab or floor using electromagnetic equipment.

Once the electromagnetic survey is complete, the work area is scanned using a concrete imaging radar device. Electromagnetic targets can be verified and confirmed, and any other structure located in the floor can be designed. 

Concrete imaging radar is completely safe to work around. Unlike X-Ray scanning services, radar does not emit harmful radiation. The device is FTC compliant, so it is safe to use in a variety of environments including airports, hospitals, and even NASA. The device is roughly the size of a standard two-slice toaster and generally does not need any project site alterations or accommodations, except for a clean scanning surface.

Electric Cables in FloorIn addition to a superior utility mark-out using paint, chalk, crayon, or other suitable marking device for the work area, we provide our clients with all of the documentation you need to procure any necessary work or excavation permits you need to proceed.

We’ll include a field report documenting out survey dates, utilities designated, equipment utilized, site contacts made, and any limitations or unusual field conditions encountered while performing the work.

We’ll also draft a field sketch depicting the embedded utilities and/or structural members we found or verified. Our field sketch will be formatted on our 11″x17″ sketch template and drawn digitally in the field by hand (not to scale). Have a construction drawing you need updated instead? We can add our field sketch to any client provided PDF document.
