SECTION 02778 <br /> HIGH DENSITY POLYETHYLENE(HDPE)GEOMEMBRANE <br /> PART GENERAL <br /> 1.1 WORK INCLUDED <br /> A. This section covers the Work necessary to furnish and install 60-mil single-sided <br /> textured high density polyethylene (HDPE) geomembrane liner, complete. <br /> B. The GEOSYNTHETICS CONTRACTOR shall furnish all labor,supervision,tools, <br /> equipment,and materials necessary to complete the HDPE geomembrane installation <br /> including,but not limited to, submittals,panel layout,seaming,patching,temporary <br /> anchorage,temporary slip sheeting,and all necessary and incidental items required to <br /> complete the Work in accordance with these Specifications and the Construction <br /> Drawings. The EARTHWORK CONTRACTOR will perform excavation and <br /> backfilling of anchor trenches and will unload the HDPE geomembrane if the <br /> GEOSYNTHETICS CONTRACTOR is not onsite. <br /> C. A leak location test will be performed on the primary geomembrane following <br /> deployment, seaming, and placement of the safety ladders and gravel logs. The <br /> GEOSYNTHETICS CONTRACTOR shall be responsible for repairing all identified <br /> leaks in the geomembrane in accordance with the applicable Specifications sections. <br /> 1.2 REFERENCES <br /> A.
