Observations of Field Condition of an Exposed Geosynthetic Liner System
Preliminary field observations during the removal of a composite geosynthetic liner system. The liner system was installed in a Subtitle D municipal solid waste landfill in San Luis Obispo, California (USA). The liner system consisted of a 1.5 mm thick black HDPE geomembrane, a needle-punched geosynthetic clay liner (GCL), and a compacted subgrade. The liner system was not covered at any time since construction. The sides of the cell were relatively steep at 2H: 1V slopes. Initially, the geomembrane was removed from the geosynthetic clay liner. The geosynthetic clay liner panels were observed to be separated at locations with gaps up to 220 mm wide and up to approximately 17 m long. The GCL is also relatively dry with granular consistency. In addition, a significant amount of bentonite migrates from the GCL had accumulated between the GCL and the geomembrane at the toe of the slope.
