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 /> <br />The QA/QC Consultant will note any non-compliance and report it to the Construction Manager. <br /> <br />4.4.4 Repair <br /> <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 /> <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 />
