<br /> Page 42 <br />• All GCLs will be overlapped and heat welded. Along the length of the mat, the overlap <br />will be 12 in. (150 mm). Along the width of the mat, the overlap will be 12 in. <br />(300 mm). Additional manufacturer’s recommendations regarding overlaps will be <br />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 />4.5.4 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 /> <br />4.5.5 Materials in Contact with GCL <br /> <br />Equipment used for placing granular material will not be driven directly on the GCL or any <br />overlying geosynthetics. Unless otherwise specified by the Design Engineer, all equipment <br />operating on soil material overlying the GCL shall comply with the maximum allowable equipment <br />ground pressures for the given cover soil thickness provided in the Specifications. <br /> <br />Installation of the GCL in appurtenant areas, and connection of the GCL to appurtenances will be <br />made according to the drawings. The Geosynthetics Contractor will ensure that the GCL is not <br />damaged while working around appurtenances. <br /> <br />Geomembranes will be placed over each section of GCL as soon as practical to preclude <br />precipitation or other moisture contact with the GCL.
