We give construction teams the confidence to dig and build safely.
Our technicians use the most advanced ground penetrating radar technology available for underground utility location, gravesite detection, rebar and post-tension cable identification, road and bridge deck analysis and more. Get a comprehensive view of what’s beneath the surfaces you’re building on.
811 should be your first call, and Vosburg Welsh should be your second. Public records don’t provide a comprehensive view of underground obstacles on private properties. We locate, confirm and map private utility lines for commercial, residential or government construction projects.
Understand the integrity and composition of concrete structures on your project before construction starts. Our concrete scanning technicians assist with rebar location, post-tension cable detection, conduit location and concrete thickness analysis.
With Ground Penetration Radar or Electronic Resistivity Tomography technology, we help you analyze the voids, risks and limitations of the surfaces you’re building or renovating. What’s not underground can be as critical to know as what is underground.
Our underground utility locators, GPR experts, concrete scanning technicians and mapping professionals have the industry experience, safety certifications and reputation you can trust.
