• The GCL will be installed with the woven geotextile up,or as otherwise indicated by the <br /> GCL Manufacturer or Design Engineer. <br /> • Geomembrane installation will immediately follow the GCL installation. All GCL that is <br /> placed during a day's work will be covered with geomembrane before the Geosynthetics <br /> Contractor leaves the site at the end of the day. <br /> • Geomembrane will not be placed on a GCL that is hydrated. <br /> • All seams in the geomembrane overlying a GCL will be welded after each geomembrane <br /> panel is placed. Heat sealing of the seam alone is not acceptable. <br /> • All defects in the geomembrane overlying a GCL and destructive sample locations will <br /> be immediately repaired. <br /> • All hydrated GCL will be removed and replaced by the Geosynthetics Contractor at no <br /> additional cost to the Owner. <br /> • On slopes steeper than 10 horizontal to 1 vertical,all GCLs shall be continuous down the <br /> slope;that is, no horizontal seam shall be allowed in the slope. <br /> • All GCLs will be overlapped. Along the length of the mat, the overlap will be 12 in. <br /> (150 mm). Along the width of the mat,the overlap will be 12 in.(300 mm). Additional <br /> manufacturers recommendations regarding overlaps will be adhered to. <br /> • The overlaps will not be nailed or stapled to the subgrade. <br /> The QA/QC Consultant will note any non-compliance and report it to the Construction Manager. <br /> 4.4.4 Repair <br /> Any holes or tears in the GCL will be repaired by placing a GCL patch over the hole;the patch will <br /> overlap the edges of the hole or tear by 2 ft (0.6 m) in all directions. If deemed necessary by the <br /> Design Engineer, the patch will be secured with a water-based adhesive approved by the <br /> Geosynthetics Contractor. Care will be taken to remove any soil or other material that may have <br /> penetrated the torn GCL. All repairs will be made at no additional cost to the Owner. The patch will <br /> not be nailed or stapled. <br /> The QA/QC Consultant will observe any repair, note any non-compliance with the above <br /> requirements and report them to the Construction Manager. <br /> Page 35 <br />
