Ground Penetrating Radar (GPR)
See Below the Surface Before You Cut
Ground Penetrating Radar (GPR), also known as concrete scanning, is one of the most important planning tools before concrete penetrations begin. Using non-destructive technology, Northwest Corp. detects hidden features below the surface to help improve safety, reduce costly mistakes, and keep projects on schedule and on budget.
Whether you're preparing for core drilling, wall sawing, slab sawing, or demolition, GPR provides accurate information about what's inside the concrete. Our experienced team locates rebar, post-tension cables, conduit, utilities, and other embedded objects so contractors can move forward with confidence.
Our Concrete Scanning Process
1. Detect
Identify hidden features beneath the concrete surface before cutting, drilling, or demolition begins.
2. Locate
Accurately locate reinforcing steel, post-tension cables, conduit, utilities, concrete thickness, concrete cover, and dowel placement to help reduce risk during construction.
3. Map
Provide a clear understanding of subsurface conditions so contractors, engineers, and project teams can make informed decisions before work begins.
Why use GPR?
Concrete Intelligence. Project Confidence.
Ground Penetrating Radar allows contractors to safely identify hidden objects before cutting or drilling into concrete. Scanning helps reduce project risk, improve jobsite safety, and avoid unnecessary repairs.

When is GPR Recommended?
Ground Penetrating Radar should be performed anytime the contents of a concrete slab, wall, or structure are unknown before cutting or drilling.
Typical applications include:
-
Core Drilling
-
Wall Sawing
-
Slab Sawing
-
Hand Sawing
-
Facility Renovations
