Cripple Creek & Victor Gold Mining Company <br />Laboratory Liner Extension <br />Final Report <br />Quality Assurance Monitoring & Test Results <br />January 14, 2014 <br />M w <br />100 ppi and achieve a Film Tear Bond upon breaking. All destructive extrusion seam <br />samples met specifications. <br />The summaries of destructive test results for seams for the geomembrane are <br />presented in Appendix H.5. Appendix A shows the destructive test sample location. <br />5.2.7 Non - Destructive Testing <br />Lone Star performed non - destructive vacuum seam testing on completed seams and <br />geomembrane repairs. AMEC monitored and documented non - destructive testing. <br />Lone Star tested extrusion welded sections with a vacuum box. Prior to vacuum box <br />testing, a soap and water solution was applied to the welded section. The vacuum box <br />was then placed over the seam area and energized with a vacuum pump capable of <br />creating a vacuum not less than 5 psi. Lone Star and AMEC observed the action of <br />the vacuum on the weld for a minimum of ten seconds. Each consecutively tested <br />weld length was overlapped a minimum of 3 inches. If soap bubbles appeared, AMEC <br />marked and documented the leak location. Lone Star then repaired the leak and <br />vacuum tested the repair. This procedure was used to test extrusion repairs and <br />extrusion patches. <br />The seam non - destructive test summaries for the geomembrane are presented in <br />Appendix H.6. <br />sAprojects \1125m -cc &v lab liner extension\h2 - design \lab liner extension \roc report\lab liner roc report.docx 13 <br />
