Newmont Goldcorp-Cripple Creek&Victor Gold Mine <br /> Technical Specification No.02777 GEOTEXTILE ■ <br /> VLF2 Phase 3 <br /> Project No 475 0106.033 <br /> December 5,2019 <br /> 5. Geotextile panels shall be deployed in such a manner as to preclude wrinkles and <br /> folds. Any wrinkle or fold that may manifest itself into other geosynthetic layers <br /> shall be removed. <br /> 6. Geotextile within the lined area shall be cut with a cutter approved by <br /> CERTIFYING ENGINEER, such as scissors. <br /> 7. Take necessary precautions to prevent damage to the underlying subgrade during <br /> placement of the geotextile. <br /> 8. During placement of geotextiles, care shall be taken not to entrap, in or beneath <br /> the geotextile, stones, excessive dust, or moisture that could damage the <br /> underlying or overlying geomembrane, cause clogging of drains or filters, or <br /> hamper subsequent seaming. <br /> 9. Following the installation of all geotextile, an examination of the entire surface <br /> shall be conducted to detect potentially harmful foreign objects. Any such foreign <br /> objects found shall be removed or the panel shall be replaced by the <br /> CONTRACTOR, at no cost to CC&V. <br /> 10. Geotextile panels shall not be deployed over frozen ground, unless approved by <br /> CERTIFYING ENGINEER. <br /> B. Seaming Procedures <br /> 1. On slopes steeper than ten (10) percent, and in all cases in which soil or granular <br /> materials are to be placed over the geotextile, all seams shall be continuously <br /> sewn. In all other applications, sewing is the preferred seaming method. <br /> 2. Seams to be sewn shall be overlapped a minimum of six (6) inches and shall be <br /> sewn with a locking stitch. Seams to be thermally bonded shall be overlapped a <br /> minimum of twelve (12) inches. <br /> 3. The thread used in sewing shall be of polymeric material having chemical <br /> resistance, and if the geotextile is to be exposed for more than thirty (30) days, <br /> ultraviolet resistance equal to or exceeding that of the geotextile. <br /> 4. CONTRACTOR shall take measures to prevent soil, granular materials, or foreign <br /> materials from entering or becoming trapped beneath the geotextile both during <br /> and following installation. <br /> C. Defects and Repairs <br /> Repair holes or tears in geotextile as follows: <br /> 1. Remove any soil or other material that may have penetrated the torn geotextile. <br /> 2. Should any tear exceed 10 percent of the width of the roll, that section of the roll <br /> shall be removed from the slope and replaced. <br /> Page 5 <br />
