® • The GCL will not be installed on a saturated subgrade or on standing water. The GCL will be installed in a way that prevents hydration of the mat prior to completion of construction of the liner system. • The GCL will not be installed during precipitation or other conditions that may cause hydration of the GCL. • All GCLs will be overlapped a minimum of 12 in. (300 mm). Additional manufacturers recommendations regarding overlaps will be adhered to. • The overlaps will not be nailed or stapled to the subgrade. The QA/QC Consultant will note any non-compliance and report it to the Construction Manager. 4.4.2 Repair Any holes or tears in the GCL will be repaired by placing a GCL patch over the hole; the patch will overlap the edges of the hole or tear by 2 ft (0.6 m) in all directions. If deemed necessary by the Design Engineer, the patch will be secured with a water-based adhesive approved by the Geosynthetics Contractor. Care will be taken to remove any soil or other material that may have penetrated the torn GCL. All repairs will be made at no additional cost to the Owner. The patch will not be nailed or stapled. The QA/QC Consultant will observe any repair, note any non-compliance with the above requirements and report them to the Construction Manager. 4.4.3 Materials in Contact with GCL Equipment used for placing granular material will not be driven directly on the GCL or any overlying geosynthetics. Unless otherwise specified by the Design Engineer, all equipment operating on soil material overlying the GCL shall comply with the maximum allowable equipment ground pressures for the given cover soil thickness provided in the Specifications. Installation of the GCL in appurtenant areas, and connection of the GCL to appurtenances will be made according to the drawings. The Geosynthetics Contractor will ensure that the GCL is not damaged while working around appurtenances. Page 38
