ameO <br /> 3. Tears shall be repaired by patching. Where the tear is on a slope or an area of stress and <br /> has a sharp end it must be rounded prior to patching. <br /> 4. Blisters, large holes, undispersed raw materials, and contamination by foreign matter <br /> shall be repaired by patches. <br /> 5. Surface of geomembrane that are to be patched shall be abraded and cleaned no more <br /> than fifteen (15)minutes prior to the repair. No more than 10% of the thickness shall be <br /> removed. <br /> D. Patches shall be round or oval in shape, and extend a minimum of six(6) inches beyond the edge <br /> of defects. All patches shall be of the same compound and thickness as the geomembrane <br /> specified. All patches shall have their top edge beveled to an approximately 45-degree angle with <br /> an angle grinder prior to placement of the patch. Patches shall be applied using approved methods <br /> only. <br /> E. The extrusion welding process shall restart by grinding the existing seam and rewelding a new <br /> seam. Welding shall commence where the grinding started and must overlap the previous seam <br /> by at least two (2) inches. Reseaming over an existing seam without regrinding shall not be <br /> permitted. <br /> F. Each repair shall be non-destructively tested, except when CERTIFYING ENGINEER requires <br /> a destructive seam sample obtained from a repaired seam. Repairs that pass the destructive test <br /> shall be taken as an indication of an adequate repair. Failed tests indicate that the repair shall be <br /> repeated and retested until passing test results are achieved. <br /> Recording the Results: Daily documentation of all non-destructive and destructive testing shall be <br /> provided to MANAGER by CQA Monitor. This documentation shall identify all seams that <br /> initially failed the test and include evidence that these seams were repaired and successfully <br /> retested. <br /> 3.11 CONFORMANCE TESTING <br /> A. During manufacturing of the geomembrane, CQA Monitor will be present to obtain and forward <br /> samples to the Quality Assurance Testing Laboratory for testing to ensure conformance with the <br /> SPECIFICATIONS. <br /> B. Samples will be taken across the entire width of the roll and shall not include the first three (3) <br /> feet. Unless otherwise stated, samples will be three (3) feet long by the width of the roll. CQA <br /> Monitor will mark the machine direction on the samples with an arrow. Unless otherwise stated, <br /> samples shall be taken at a frequency of no less than one per one hundred fifty thousand(150,000) <br /> square feet. As a minimum, the following tests will be performed to verify conformance to the <br /> design SPECIFICATIONS with minimum values specified in Section 2776,Article 2.01. <br /> Section 02776 Page 21 of 22 May 9,2012 <br /> Geomembrane Revision 1 <br />
