Safely locate buried gas, water, sewer, and electric lines with advanced GPR and EM tools. Our San Antonio crews mapped utilities for a major construction site, allowing work to proceed without delays or utility strikes.

We supported a telecom provider by identifying fiber routes before trenching began. Using subsurface imaging and GIS tools, we prevented service disruptions and accelerated permitting in dense San Antonio corridors.

Need precise confirmation? We work with engineers to plan and oversee potholing operations. Our mapped utility records reduce unnecessary test holes and speed up inspections — all without damaging assets or roadways.
