GPRS Detects Underground Storm Water Detention System - MI

Ground Penetrating Radar Systems, Inc. (GPRS) was recently called to a project in Ann Arbor, Michigan. The purpose of the investigation was to verify an existing underground storm water detention system. In order to obtain proper building permits to move forward on the construction project, the contractor had to prove that the system was installed per engineering specs. Rather than dig up and potentially compromise the system, the contractor called GPRS for help. For the GPR portion of the survey, a 400MHz antenna with the SIR-3000 processing unit manufactured by Geophysical Survey Systems, Inc, (GSSI) was used. The average effective penetration depth encountered during the GPR survey was approximately 8.0 feet below ground surface (bgs). The GPR survey area was conducted in an east/west and/or north/south direction using approximate 5.0 foot surface grid spacing.

GPRS, Inc. also has the capabilities of locating conduits, rebar, and post tension cables in a concrete slab. For more information, to request a quote or to schedule your next project, please contact Brian Chmielewski at 517-512-0018 or by email at brian.chmielewski@gp-radar.com.
