GPRS we believe that data control = damage control and we are committed to the pursuit of 100% subsurface damage prevention – on every job, in every market, nationwide.

That’s why every one of our 500 national “boots on the ground” team of elite Project Managers are trained in Subsurface Investigation Methodology (SIM). SIM elevates a mere technician to an expert professional with the cross-technology training and industry-leading processes that can locate, map, capture, measure, and scan your entire site or facility, above and below-ground, to provide you with the real-time actionable information you need to plan, design, manage, dig, and build better.

GPRS is the only company in the U.S. that can capture your entire site or facility, above and below-ground, to provide you with accurate as-builts, private and public utility maps, 2D CAD drawings, and 3D photogrammetry and Building Information Models (BIM) that can integrate surface and subsurface existing conditions and construction progress capture to provide cloud-based, digital mapping & modeling solutions for the construction, architecture, engineering, facility management, and related industries via SiteMap®.

What is Recycled Foamed Glass Aggregate? ‍

Recycled foamed glass aggregate is made from post-consumer recycled glass, such as bottles and other glass products. The production process begins by grinding the glass to a powder, which is then mixed with a foaming agent, typically silicon carbide. This mixture is heated in a kiln, where the foaming agent reacts to the heat, creating millions of tiny bubbles within the glass, transforming it into a highly porous, lightweight material. Once cooled, this material is crushed into aggregate sizes that can be used in various construction applications like widening roadways, acting as fill under concrete slab foundations, and insulating electrical transmission lines, among others. The EPA gave the material the green light back in the 1980s, but it has just recently been gaining traction and has been approved for use in more than 22 states in the U.S.
