- Production Lot number and Individual Roll number <br /> 3.10. Accessory Bentonite - Any accessory bentonite used for sealing seams,penetrations, <br /> or repairs, shall be the same granular bentonite as used in the production of the GCL <br /> itself. <br /> 4.0 EXECUTION - The following installation procedures are as specific as possible while <br /> recognizing that the specific requirements of the project may necessitate minor <br /> modifications. Significant deviations from these procedures shall be pre-approved by <br /> the project engineer or other designated party. <br /> 4.1. Shipping and Handling Equipment- The party responsible for unloading the GCL <br /> shall contact the manufacturer prior to shipment to determine the correct unloading <br /> methods and equipment if different from the pre-approved and specified methods. <br /> Bentofix Geosynthetic Clay Liner(GCL) must be supported during handling to ensure <br /> worker safety and prevent damage to the liner. Under approved circumstances only, <br /> shall the rolls be dragged, lifted from one end, lifted with only the forks of a lift truck <br /> or pushed to the ground from the delivery vehicle. <br /> The QCA inspector shall verify that proper handling equipment exists which does not <br /> pose any danger to installation personnel or risk of damage or deformation to the liner <br /> material itself. Suitable handling equipment is described below: <br /> 4.1.1. Spreader Bar Assembly - A spreader bar assembly shall include both a core <br /> pipe or bar and a spreader bar beam. The core pipe shall be used to uniformly <br /> support the roll when inserted through the GCL core while the spreader bar <br /> beam will prevent chains or straps from chafing the roll edges. <br /> 4.1.2. Stinger - A stinger is a rigid pipe or rod with one end directly connected to a <br /> forklift or other handling equipment. If a stinger is used, it should be fully <br /> inserted to it's full length into the roll to prevent excessive bending of the roll <br /> when lifted. <br /> 4.1.3. Roller Cradles - Roller cradles consist of two large diameter rollers spaced <br /> approximately 3 inches apart, which both support the GCL roll and allow it to <br /> freely unroll. The use of roller cradles shall be permitted if the rollers support <br /> the entire width of the GCL roll. <br /> 4.1.4. Straps - Straps may be used to support the ends of spreader bars but are not <br /> recommended as the primary support mechanism. As straps may damage the <br /> GCL where wrapped around the roll and generally do not provide sufficient <br /> uniform support to prevent roll bending or deformation, great care must be <br /> exercised when this option is used. <br /> 4.2. GCL Inspection Upon Delivery-Each roll shall be visually inspected when unloaded <br /> to determine if any packaging or material has been damaged during transit. Repairs to <br /> damaged GCL shall be performed in accordance with Section 4.6.5 of this <br /> specification. <br /> Bentofix Drop-In Specification Bentofix is a registered trademark of NAUE GmbH&Co.KG <br /> 7 R1/13/06 <br />
