Foothill Sanitary Landfill — Module 1 December 2003 <br />County of San Joaquin _ Job No. 031602.00.02 <br />5.4.5 Repair <br />All materials were checked for defects during deployment and all holes or tears were <br />identified and repaired prior to placement of the cover materials. <br />5.5 Geocomposite <br />A geocomposite drainage layer was placed as part of the LCRS for the side slopes. The <br />geocomposite consisted of a nonwoven geotextile fused to both sides of a HDPE <br />geonet. <br />5.5.1 Receiving Inspection <br />Upon arrival by truck shipment, the unloading and storage of the geocomposite rolls <br />were observed by Vector's CQA Monitors. Each roll of geocomposite was logged in by <br />roll number and the roll numbers then cross-checked against the quality control <br />documents provided by the Contractor as a submittal. Following this inspection and <br />approval, the material was released to the Contractor for installation. A copy of the log <br />of geocomposite received has been included in Appendix M. The manufacturer's QC <br />0 data have also been included within Appendix <br />5.5.2 Conformance Testing <br />Select samples of the geocomposite were cut from random rolls of the geocomposite at <br />the manufacturing plant by Precision for conformance testing in accordance with the <br />project specifications and CQA manual. Conformance testing for the geotextile and <br />geonet components of the geocomposite included the following: <br />Geonet Component <br />• thickness (ASTM D5199) <br />• density (ASTM D1505) <br />• carbon black content (ASTM D1603) <br />Geocomposite <br />• routine transmissivity (ASTM D4715) <br />• design transmissivity (ASTM D4716) <br />0 • ply adhesion (GRI GC7) <br />Vector Engineering, Inc. • 143E Spring Hill Drive • Grass Valley, CA 95945 • (530) 272-2448 <br />37 <br />
