We Visualize The Built World® to help you reduce costs and change orders, save time, and keep everyone on your project safe.
- Utility Locating: 60% of all utility lines are private, not public. 811 locates only public utilities, and does not provide depths for those locates. Our utility locating services employ both GPR and EM technology to provide a necessary and accurate supplement to One Call locates to provide utility mapping, and clearances for soil boring and direction drilling.
 - Concrete Scanning: Every GPRS concrete scan is backed by our exclusive Green Box Guarantee. Our accuracy rate for post tension concrete imaging is 99.8%+, so when we provide you with a green “clear” space to saw, cut, core, or drill, you know that you can count on our data when planning your project. If we get it wrong, we will pay for the cost of the damage.
 - Ground Penetrating Radar: A GPR scanner emits radio waves into a concrete slab or site subsurface, then detects the interactions between those signals and any buried objects such as utilities, rebar, post tension cable, or underground storage tanks (USTs). Specialized training and experience are required to properly interpret the signals, and when a professional utility locator does so, they can usually provide highly accurate locations and maps of subsurface facilities and features.
 
- Our comprehensive services include ground penetrating radar (GPR) and electromagnetic (EM) locating for post tension concrete imaging and subsurface utility locating, 3D laser scanning for millimeter-accurate measurements for any facility, acoustic leak detection and NASSCO certified video pipe (CCTV) inspection for facilities and municipal infrastructure, and drone imaging for orthomosiac aerial photogrammetry, all conducted by elite, SIM certified Project Managers.
