TECHNICAL SPECIFICATIONS <br />2.4 ACCESSORY BENTONITE <br />A. The granular bentonite sealing clay used for overlap seaming, penetration sealing and repairs shall be <br />made from the same natural sodium bentonite as used in the GCL and shall be as recommended by the <br />GCL MANUFACTURER. Seaming of GCLs shall be conducted in accordance with the <br />MANUFACTURER'S guidelines. <br />PART 3- EXECUTION <br />3.1 SHIPPING AND HANDLING <br />A. The MANUFACTURER assumes responsibility for initial loading of the GCL. Unloading, on -site <br />handling and storage of the GCL are the responsibility of the CONTRACTOR, INSTALLER or other <br />designated party. <br />B. A visual inspection of each roll should be made during unloading to identify if any packaging has been <br />damaged. Rolls with damaged packaging should be marked and set aside for further inspection. The <br />packaging should be repaired prior to being placed in storage. <br />C. The party responsible for unloading the GCL should contact the MANUFACTURER prior to shipment <br />to ascertain the appropriateness of the proposed unloading methods and equipment. <br />3.2 STORAGE <br />A. Storage of the GCL rolls shall be the responsibility of the INSTALLER. A dedicated storage area shall <br />be selected at the job site that is away from high traffic areas and is level, dry and well drained. <br />B. Rolls should be stored in a manner that prevents sliding or rolling from the stacks and may be <br />accomplished by the use of chock blocks. Rolls should be stacked at a height no higher than that at <br />which the lifting apparatus can be safely handled (typically no higher than four). <br />C. All stored GCL materials and the accessory bentonite must be covered with a plastic sheet or tarpaulin <br />until their installation. <br />D. The integrity and legibility of the labels shall be preserved during storage. <br />3.3 GCL PLACEMENT <br />A. GCL rolls should be delivered to the working area of the site in their original packaging. Immediately <br />prior to deployment, the packaging should be carefully removed without damaging the GCL. The <br />orientation of the GCL should be in accordance with the design DRAWINGS, or MANUFACTURER <br />recommendations if not otherwise specified. Packaging waste shall be disposed of daily into landfill or <br />dumpster as designated by MANAGER. <br />B. Equipment, which could damage the GCL, shall not be allowed to travel directly on it. If the installation <br />equipment causes rutting of the subgrade, the subgrade must be restored to its originally accepted <br />condition before placement continues. <br />C. Care must be taken to minimize the extent to which the GCL is dragged across the subgrade in order to <br />avoid damage to the bottom surface of the GCL. A temporary geosynthetic subgrade covering <br />commonly known as a slip sheet or rub sheet may be used to reduce friction damage during placement. <br />D. The GCL panels shall be placed parallel to the direction of the slope. <br />E. All GCL panels should lie flat on the underlying surface, with no wrinkles or folds, especially at the <br />exposed edges of the panels. <br />F. Only as much GCL shall be deployed as can be covered at the end of the working day with soil, a <br />geomembrane, or a temporary waterproof tarpaulin. The GCL shall not be left uncovered overnight.
