Final Construction Quality Assurance Report— WMU FU -13 <br />Forward Landfill <br />5.0 GEOSYNTHETICS CQA <br />5.1 GENERAL DESCRIPTION OF ACTIVITIES <br />• <br />The geosynthetics components of WMU FU -13 consisted of geosynthetic clay liner (GCL), single - <br />side textured (SST) and double -side textured (DST) 60 -mil HDPE geomembrane; geocomposite; <br />cushion and filter geotextiles, geocomposite and geogrid. The installation and associated CCIA <br />provided for each of these components are discussed within the following sections. <br />5.2 GEOSYNTHETIC CLAY LINER (GCL) <br />5.2.1 General <br />The GCL product used in the construction of WMU FU -13 was Bentoliner manufactured by GSE. <br />This type of GCL material consists of granular bentonite encapsulated by two non -woven <br />geotextiles. <br />5.2.2 GCL Manufacture and Delivery <br />5.2.2.1 Receiving Inspection <br />Upon arrival by truck shipment, GLA's CQA Monitor observed the unloading and storage of the <br />GCL rolls. As each roll was unloaded from the delivery truck, the roll number was recorded in <br />the Receiving Logs, and then crosschecked with the manufacturer's quality control documents <br />(MQC Certifications) provided by the GCL manufacturer. These documents were reviewed by <br />GLA's Engineer of Record. Following this review, the material was approved for deployment. A <br />copy of the Receiving Logs and MQC certificates are included in Appendix H. <br />5.2.2.2 GCL Conformance Testing <br />The conformance testing on the GCL was performed by TRI. Conformance testing included the <br />following: <br />• hydraulic conductivity (ASTM D-5084); <br />• peel strength (ASTM D-4632, modified for 180 degree peel of GCL); and <br />interface shear strength (conducted by GLA). <br />A summary of the conformance test results is presented in Table 5. Interface shear testing was <br />conducted for the GCL/geomembrane/geocomposite interface. Results of the conformance <br />testing indicated that the materials met the requirements of the project specifications. <br />Detailed test results, including the GCL interface tests, are provided within Appendix H. <br />18 Geo -Logic <br />ASSOCIATES <br />
