We're a locally owned and operated business with the capacity to handle projects of any size

SIS GPR was founded by Robert J. Black, Jr., a seasoned land surveyor with over 30 years of experience in construction and road building. Witnessing firsthand the limitations of traditional utility location methods, Robert saw the potential of Ground Penetrating Radar (GPR) to transform project safety and efficiency.
