Colorado Legacy Land Former Schwartzwalder Mine <br /> North Waste Rock Pile Diversion Channel <br /> E. Seam Sample Failures <br /> 1. If any sample fails seam testing two new samples shall be taken about 10 ft. each <br /> side of the failing sample, and so on until two passing samples define the limits <br /> of the non-conforming seam. <br /> 2. The seam shall be repaired between the two passing samples. <br /> F. Flaws and Repairs <br /> 1. All non-penetrating linear flaws less than 0.125 in.wide may be repaired with no <br /> more than one extrusion bead of the same base polymer as the geomembrane. <br /> 2. Penetrating holes less than 0.125 in. in diameter that do not expose scrim yarns <br /> may also be repaired with no more than one bead application. <br /> 3. Holes that expose scrim yarns and those that are more than 0.125 in. in diameter <br /> shall be patched with the same geomembrane with patch yarns oriented in the <br /> same direction as in the geomembrane. The patch shall extend at least 3 in. from <br /> the edge of the nearest damage if the damaged area is less than 1 in. in diameter. <br /> When damage exceeds 1 in. in diameter the patch shall extend at least 6 in. from <br /> the nearest damage. <br /> 4. Under no circumstances will parallel and overlapping beads be used to fill in a <br /> flawed area or a gap. <br /> 5. All corners on patches shall be rounded. <br /> 6. All patch extrusion welds shall be vacuum box tested and hot air patches can be <br /> either air lanced or vacuum tested and the results recorded. <br /> 7. All patches shall be numbered and their sizes and locations recorded <br /> 3.03 Geomembrane Acceptance <br /> A. The Installer shall retain all ownership and responsibility for the geomembrane until <br /> acceptance by the Owner. In the event the Installer is responsible for placing a protective <br /> cover over the geomembrane,the Installer shall retain ownership and responsibility for <br /> the geomembrane until the protective cover is placed. The geomembrane will be accepted <br /> when the following activities have occurred: <br /> 1. The installation is finished. <br /> 2. Signed QC certificates for each roll/panel of geomembrane have been supplied <br /> by the Installer by the Engineer. <br /> 3. All documentation required by the specification has been received. <br /> —END OF SECTION— <br /> Section 026617-Geomembrane Page 11 <br />
