Reducing Environmental Impact Using GPR
4/4/19
It is possible to minimize environmental impacts and greatly reduce site costs by employing Ground Penetrating Radar (GPR) field methods. GPR is increasingly being used in Australian to minimize excavation and provide trenchless solutions. GPR is often employed along with non-destructive digging (NDD) such as a hydro-vac or dry suction. The GPR field methods employed include initial scanning with GPR to locate assets and detect any unknown objects prior to excavation or NDD.
On-site interpretation of GPR data as it is collected to understand key locations and site conditions to decide on an excavation or NDD strategy. Selective core hole drilling to confirm asset location or tap into the existing asset to install a new connection or water stop. Reporting and post-processing of GPR data to document key locations and the methods used. These methods form an overall strategy for GPR scanning which can be applied to future projects.
