4.7.1.5. Slope Placement- When covering GCL on sloped areas, cover soil <br /> should be pushed up-slope to minimize tension on the GCL. <br /> 4.7.2. Geosynthetic Cover - Precautions shall be taken to prevent damage to the GCL <br /> by restricting the use of heavy equipment over the liner system. <br /> 4.7.2.1. Equipment- Installation of the overlying geosynthetic component can <br /> be accomplished through the use of lightweight, rubber-tired <br /> equipment such as a 4-wheel all-terrain vehicle (ATV). This vehicle <br /> can be driven directly on the GCL, provided the ATV makes no <br /> sudden stops, starts, or turns. <br /> 4.7.2.2. Placement- Smooth HDPE may be dragged across the GCL surface <br /> with equipment or by hand labor during positioning. Similarly,the <br /> HDPE may be unrolled with the use of low ground pressure <br /> equipment. <br /> 4.7.2.3. Use of Textured Liners - If a textured geomembrane is placed over the <br /> GCL, a slip sheet(such as 20-mil smooth HDPE)may first be placed <br /> over the GCL in order to allow the geomembrane to slide into its <br /> proper position. Once the overlying geomembrane is properly <br /> positioned,the slip-sheet shall be carefully removed paying close <br /> attention to avoiding any movement to the geomembrane. <br /> 5.0 ACTIVATION - If the GCL will be utilized for the control of non-aqueous phase liquids, <br /> prehydration may be necessary. The GCL manufacturer shall be contacted for these <br /> cases for site specific recommendations. <br /> 6.0 WARRANTY - GCL material as well as installation warranties provided by the <br /> manufacturer and installer shall be made a part of the final submittal documents. <br /> END OF SECTION <br /> Bentofix Drop-In Specification Bentofix is a registered trademark of NAUE GmbH&Co.KG <br /> 12 RI/13/06 <br />
