The GPRS Green Box Guarantee is an industry-leading, proprietary program that provides contractors the necessary assurance of safety when drilling, cutting, or coring through an elevated concrete deck. GPRS Project Managers place green boxes over areas that have been confirmed to be clear of obstruction.

The GPRS Green Box Guarantee emphasizes four critical project factors: safety, efficiency, cost savings, and clear communication. Each benefit comes together to enhance GPRS's 99.8% accuracy rating and allows clients to join in our fight against subsurface damage. Don't forget, GREEN MEANS GO!

No, Green Box Guarantee is an industry-leading proprietary program to help prevent injuries and damages. We want to provide contractors with the necessary comfort of certainty when coring and drilling concrete. GPRS offers this program as a part of its pursuit of 100% subsurface damage prevention. We are the only company to provide the Green Box Guarantee as we’re the only company that can lean on our industry-leading damage-free rate of 99.8%.

GPRS's Green Box Guarantee is designed explicitly for elevated concrete slabs, indicating areas free of obstructions such as rebar, post-tension cables, and electrical conduits. While the Green Box Guarantee does not apply to all concrete, utility, and video pipe inspection jobs – we stand behind our work. We have a 99.8% accuracy on over 300,000 projects, and we continue to pursue 100% subsurface damage prevention. GPRS is so confident in our Green Box Guarantee that we will pay the cost of damage after coring or drilling.

Using the Subsurface Investigation Methodology (SIM) process is the key to our Project Managers' success. We place green boxes on elevated concrete slab locations we're confident are clear to core, cut, or drill through. Our green boxes communicate that all critical targets such as rebar reinforcement, electrical conduits, and post-tension cables are absent, and no obstruction is present.
