Concrete GPR LLC, Expert Ground Penetrating Radar Service for Oregon and Washington

Expert Ground Penetrating Radar Service for Oregon and Washington

Ground penetrating radar (GPR) is a technology to look inside concrete and soil.  When used with training and skill, it can be used to find things without digging, cutting, or demolishing.  GPR is a geophysical method, very similar to sonar, in which electromagnetic waves are sent into the ground and recorded as they reflect back.  These signals are dependent on the location of the GPR antenna — if the antenna doesn’t move, the signal doesn’t change, and the information is essentially unusable.  To get good information and really see what’s down there, the antenna needs to be moved in a straight line across the area to be scanned, recording enough data to get a thorough comparison.

Realtime 2D Linescans

By carefully evaluating a series of straight line (2D) data samples, our skilled technicians can investigate many projects in real-time.  With a linescan project we can mark our findings directly on the scanned area so your work can proceed immediately.  It’s a bit like calling 811, but a whole lot more.  Some common 2D linescanning services include: marking post-tension cables and determining safe core drilling locations in reinforced concrete; locating utilities like water or gas mains and service drops for safe excavation and directional boring; quickly clearing anchor embeds for seismic reinforcement and equipment installation.

3D Grid Scanning

Linescanning has limitations, and isn’t appropriate for every project.  That’s where 3D grid scans come in.  With a 3D scan, we create a high density grid of ground penetrating radar data for post-processing in the office.  This allows us to evaluate your project areas in precise detail. Because we’re working with a 3D data model, we can report our findings back to you in detailed reports.  We can even output 3D DXF files that you can incorporate into your CADD and BIM projects.  3D scans can overcome the limitations of poor data quality and obstructed site access to accomplish projects that aren’t feasible with realtime linescanning.  They are also much more cost efficient for tackling large projects, and provide permanent documentation for insurance, inspection, due diligence, and future projects.

What We Do

Concrete GPR LLC is the Pacific Northwest specialist in 2D and 3D ground penetrating radar scanning for a full range of service applications.  We provide non-destructive testing and inspection services for everything from common rebar and post-tension to complex utility site surveys.  Based in Albany Oregon, we provide regular service all along the I-5 corridor, from Ashland to Kelso, and throughout the Oregon Coast.  Longer road travel is no problem, and we are happy to visit Bend, Seattle, Spokane, Boise, or Sacramento when your project needs us.  Our crew even has plenty of experience flying to places like Chicago, Maryland, Alaska, Guam, and Mexico to perform some of the most complex projects.

Our unique combination of technical expertise and dedication to service set us apart from the field:

  • Depth of technical expertise
    • Staff has almost a decade of highly technical experience.
    • State of the art ground penetrating radar equipment systems.
    • Unparalleled ability to create 3D data from extremely complex projects.
