TECHNICAL SPECIFICATIONS <br />Seams at the ends of the panels should be constructed such that they are shingled in the direction of the <br />grade to prevent the potential for runoff flow to enter the overlap zone. <br />D. Bentonite- enhanced seams are constructed between the overlapping adjacent panels described above. <br />The underlying edge of the longitudinal overlap is exposed and then a continuous bead of granular <br />sodium bentonite is applied along a zone defined by the edge of the underlying panel. A similar bead of <br />granular sodium bentonite is applied at the end -of -roll overlap. The granular bentonite shall be applied <br />at a minimum application rate of one - quarter pound per lineal foot (0.25 lb /ft). <br />3.7 DETAIL WORK <br />A. The GCL shall be sealed around penetrations and embedded structures embedded in accordance with <br />the GCL MANUFACTURER recommendations. <br />B. Cutting the GCL should be performed using a sharp utility knife. Frequent blade changes are <br />recommended to avoid damage to the geotextile components of the GCL during the cutting process. <br />3.8 DAMAGE REPAIR <br />A. If the GCL is damaged (pre- hydrated, torn, punctured, perforated, etc.) during installation, it may be <br />possible to repair it by cutting a patch to fit over the damaged area. The patch shall be obtained from a <br />new GCL roll and shall be cut to size such that a minimum overlap of twelve (12) inches is achieved <br />around all of the damaged area. Granular bentonite or bentonite mastic should be applied around the <br />damaged area prior to placement of the patch. It may be desirable to use an adhesive to affix the patch <br />in place so that it is not displaced during cover placement. <br />END OF SECTION 02776.2 <br />Geosynthetic Clay Liner (GCL) August 28, 2013 <br />02776.2-6 Revision 0 <br />S \Projects \1550 - CCdV Field Spt CQA PSES Bldg \8 0 Project Engineering and Design \8 2 Specifications\PSES Pipe Rack Liner Extension Specifications \02776 2 Geocompos¢e Clay <br />Liner doex <br />
