Non-destructive Investigation Services for Damage Prevention and Personal Safety
Ground penetrating radar (GPR) is a technology to look inside concrete and soil. With proper 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. Our technicians are trained in both GPR and construction methods, so they can accurately interpret these reflections to estimate the location and characteristics of embedded objects.
Realtime 2D Linescans – Keep your active project on schedule
By carefully evaluating a series of straight line (2D) radargram data samples, our skilled technicians can rapidly investigate many projects in real-time. With this method we usually 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. Common 2D linescanning services include:
- marking post-tension (PT) cables and determining safe drilling locations in concrete
- locating utilities like power, water, and gas for safe excavation and directional boring
- quickly confirming safe anchor holes for equipment, hangers, and seismic reinforcement
3D Grid Scanning – Design/build with accurate information about existing conditions
Grid scanning allows us to create a 3D model of ground penetrating radar data for post-processing and interpretation in the office. This allows us to evaluate your project areas in comprehensive 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 CAD and BIM plans with or without GPS.
- Voiding beneath concrete slabs
- Utility mapping in large areas
- Integration into cloud models and permanent site documentation
3D scans can overcome the limitations of poor data quality and obstructed site access to accomplish projects that aren’t feasible otherwise. They are also much more cost efficient for tackling large projects, and provide permanent documentation for insurance, inspection, due diligence, and future projects.
