Ground Penetrating Radar Systems

What Ground Penetrating Radar Systems does

Ground Penetrating Radar Systems (GPRS) is a US-based infrastructure visualization services firm headquartered in Maumee, Ohio, founded in 2001 and operating as a private LLC. The company specializes in detecting and mapping underground utilities, scanning concrete structures, inspecting sewer and water pipelines via CCTV, performing 3D laser scanning, and locating pressurized water leaks. All field work is executed by more than 500 SIM-certified Project Managers stationed in every US state, each trained through a proprietary 440-hour Subsurface Investigation Methodology (SIM) program that the company cites as the basis for a 99.8% accuracy rate and its exclusive Green Box Guarantee on concrete imaging.

GPRS delivers services through a field-to-finish workflow that integrates ground penetrating radar, electromagnetic locating, CCTV video pipe inspection (with NASSCO-certified WinCan reports), Leica LiDAR scanning, Matterport virtual tours, and acoustic leak detection. Output is consolidated into the SiteMap GIS platform, which is described as patent pending and packages georeferenced utility data, BIM models, CAD files, photos, and inspection videos for customers in tiered subscriptions ranging from a free Personal tier bundled with utility locate projects to paid Project, Pro, and Premium tiers. Hardware integrations include Leica survey-grade scanners, Matterport cameras, and WinCan pipe inspection software.

The company generates revenue primarily through project-based professional services billed per engagement with Net 30 terms, supplemented by recurring SiteMap subscription fees. Go-to-market is a nationwide direct field sales model augmented by an inside sales and customer service center, self-service via the SiteMap platform and iOS/Android mobile apps, and virtual presentations for enterprise prospects. Customer concentration is spread across architecture/engineering/construction firms (PCL, Turner, Hensel Phelps, Mortenson, Gilbane, AECOM, Jacobs, Arcadis, Tetra Tech, Balfour Beatty), facility operators, retail and food-service chains (Starbucks, Chick-fil-A, Target), automotive (Tesla), energy and utilities (Chevron, Marathon Petroleum, PG&E, Florida Power & Light), aerospace and defense (Lockheed Martin), and higher education (University of Michigan, University of Toledo). Growth has been driven by an aggressive acquisition strategy, with 11 deals completed since at least 2019 including the 2021 acquisition of New York Leak Detection backed by private equity sponsor Kohlberg, the 2024 acquisition of Existing Conditions, and the May 2025 acquisition of 2-D As-Built Floor Plans.
