Rail Car Dumper Installation GPR Scan, Canfor Pulp LP
Allnorth provided ground-penetrating radar (GPR) scanning services to determine the extent of hydraulic fluid spillage that had occurred in the ground around an existing rail car dumper installation. Allnorth conducted three types of scans to determine the extent of the spill. A 200 MHz utility scan was conducted through the wall of the pump house to identify fluid pooling in the soil beyond the wall. A 1.6 GHz structure scan was conducted on the walls and ceiling of the reclaim conveyor dump pit to locate rebar and aid in core drilling. A 200 MHz utility scan was performed on the surface above and around the reclaim conveyor dump pit, as well as around the dumper where the initial spill occurred.
Through the use of GPR scanning, Allnorth was able to provide CPLP with additional information and insight to better facilitate decisions regarding repair.
Allnorth’s responsibilities for this project included:
- On-site ground-penetrating radar (GPR) scanning
- Data processing and reporting
