B. Seaming Procedures <br />. 1. On slopes steeper than ten (10) percent, and in all cases in which soil or granular <br />materials aze to be placed over the geotextile, all seams shall be continuously sewn. Tn <br />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 sewn <br />with a locking stitch. Seams to be thermally bonded shall be overlapped a minimum of <br />twelve (12) inches. <br />3. The thread used in sewing shall be of polymeric material having chemical resistance, <br />and if the geotextile is to be exposed for more than thirty (30) days, ultraviolet <br />resistance equal to or exceeding that of the geotextile. <br />4. CONTRACTOR shall take measures to prevent soil, granulaz materials, or foreign <br />materials from entering or becoming trapped beneath the geotextile both during and <br />following installation. <br />C. Defects and Repairs <br />Repay holes or tears in geotextile as follows: <br />1. Remove any soil or other material that may have penetrated the tom geotextile. <br />2. Should any tear exceed 10 percent of the width of the roll, that section of the roll shall <br />be removed from the slope and replaced. <br />3. On slopes steeper than 10:1 (hotizontal:vertical), sew into place, in accordance with <br />• Article 3.01(B) of this Section, a patch made from same geotextile. Use continuous <br />sewing. <br />4. On slopes shallower than 10:1 (horizontal:vertical), sew geotextile patch into place <br />using continuous (preferred) or spot seam in place a patch made from same geotextile, <br />with a minimum 24-inch overlap in all directions. <br />*" END OF SECTION "* <br />• <br />Section 02777 Page 5 of 5 December 9, 1998 <br />Geotextile Golder Associates Revision 2 <br />I.WN2203\b10NCF.RTREPo903\APPINpSW PPEO2T!]R2.DOC <br />
