Project CICL (PELM)
Client required BLD to install a monitoring system in a 23-acre landfill cell. The landfill cell was constructed from the bottom up with a prepared subgrade surface, geosynthetic clay liner (GCL), secondary 1.5 mm HDPE geomembrane, a layer of sand, geofabric, approximately 35 cm of compacted clay material, primary 2.0 mm HDPE geomembrane, and approximately 50 cm of protective clay soil liner. Approximately 271 sensors were installed in a 20 meter by 20 meter grid system. All sensors were connected to PELM Stations throughout the cell where interaction with a resistivity meter takes place.
Our control panels interfaces with the resistivity meter to monitor specific sensors when running the PELM Survey.
During the calibration process, we simulate an artificial leak to ensure all of our sensors are collecting data accordingly.
From one station we are capable to energize the entire survey area to collect efficient data.
BLD's primary objective is to find any discontinuities in the geomembrane to prevent any leakage. Our results provide our clients with a visual conformation that our services are accurate and effective. These leaks can be created from either the manufacturing process or other physical phenomena.
