The GCL shall be protected from moisture, excessive heat or cold, puncture, or <br /> other damaging or deleterious conditions. The GCL shall be stored off the ground <br /> and out of direct sunlight. Any additional storage procedures required by the <br /> manufacturer shall be the GEOSYNTHETICS CONTRACTOR'S responsibility. <br /> 1.8 SEQUENCING AND SCHEDULING <br /> A. A pre-installation meeting shall be held to coordinate the installation of the <br /> geosynthetic clay liner with the installation of other components of the lining <br /> system. <br /> B. The geosynthetic clay liner shall be on-site fourteen days prior to the scheduled <br /> installation date to allow for completion of acceptance testing. <br /> C. The GCL shall be constructed concurrently with the HDPE Geomembrane and shall <br /> be completely covered with completed HDPE geomembrane at the end of each <br /> working day. GCL panel placement shall not precede HDPE geomembrane panel <br /> placement by more than four GCL panels. <br /> PART 2 PRODUCTS <br /> 2.1 PROPERTIES <br /> A. The GCL products shall have the following properties. <br /> 1. The GCL shall consist of a layer of bentonite encapsulated between two <br /> nonwoven geotextiles. The bentonite shall be a high quality, natural sodium <br /> bentonite composed of a minimum of 90 percent montmorillonite, by dry <br /> weight, when tested with X-ray diffraction methods. Its free swell shall be a <br /> minimum of 24 ml/2g(ASTM D5890) and fluid loss shall be a maximum of <br /> 18 ml (ASTM D5891). <br /> 2. The GCL shall be internally reinforced, through a process such as needle <br /> punching, through the top and bottom layers of geotextile and the bentonite. <br /> The reinforcing fibers shall be a polypropylene thread. The tensile strength <br /> of the fibers shall not be affected by hydration with water. <br /> 3. Prior to packaging the finished product, the manufacturer shall inspect each <br /> roll, over the entire surface area, for the presence of sewing needles. All <br /> needles shall be removed or the rolls shall be rejected. <br /> FORWARD LANDFILL 3 02777 <br /> GEOSYNTHETIC CLAY LINER(GCL) <br />
