11. When repeated trial weld fails,do not use welding apparatus and welder until <br /> deficiencies or conditions are corrected and two consecutive successful trial <br /> welds are achieved. <br /> 3.3 INSTALLATION <br /> A. Deployment. <br /> 1. Give careful consideration to the timing and temperature during deployment. <br /> The GEOSYNTHETICS CONTRACTOR shall verify that (a) there is no <br /> bridging or stresses in the geomembrane and(b) there are no wrinkles in the <br /> geomembrane that will fold over when covering with soil material. Ideally, <br /> deployment,welding,and covering should all occur at the same temperature. <br /> In a practical sense the GEOSYNTHETICS CONTRACTOR should strive to <br /> perform these activities within as narrow a temperature range as practical, <br /> and avoid these activities during peak hot or cold conditions. <br /> 2. Panel Identification: Assign each panel an identifying code number of letter <br /> consistent with the GEOSYNTHETICS CONTRACTOR's submitted panel <br /> layout drawing. The coding is subject to approval by the QA/QC <br /> CONSULTANT. <br /> 3. Daily Panel Deployment: Deploy no more panels in one shift than can be <br /> welded or secured during that same shift. <br /> AOL 4. Do not deploy in the presence of excessive moisture,fog,dew,precipitation, <br /> ponded water, or high winds. <br /> 5. Do not damage geomembrane by handling, by trafficking, or leakage of <br /> hydrocarbons or any other means. <br /> 6. Do not wear damaging shoes or engage in activities that could damage the <br /> geomembrane. <br /> 7. Unroll geomembrane panels using methods that will not damage, stretch or <br /> crimp geomembrane. Protect underlying surface from damage. <br /> 8. Use methods that minimize wrinkles and differential wrinkles between <br /> adjacent panels. <br /> 9. Remove wrinkled or folded material. <br /> 10. Place ballast on geomembrane that prevents uplift from wind. <br /> 11. Use ballast that will not damage geomembrane. <br /> 12. Protect geomembrane in area of heavy traffic by placing protective cover <br /> which is compatible with and will not damage geomembrane. <br /> 13. Repair damage to subgrade or other underlying materials prior to completing <br /> deployment of geomembrane. <br /> FORWARD LANDFILL 02778 <br /> HIGH DENSITY POLYETHYLENE <br /> 13 (HDPE)GEOMEMBRANE <br />
