Laboratory govern seam acceptance. In no case shall field testing of installed seams be used for final acceptance. Testing shall include peel adhesion and bonded seam strength (shear; ASTM D6392). At least five specimens each shall be tested for peel and sheer. Minimum test values are presented in the Specifications. The Independent Testing Laboratory shall provide test results within 24 hours after receipt of samples for testing. Certified test results shall be provided within 5 days. The Geotechnical CQA Monitor shall document all test results on appropriate forms and shall immediately notify the Geotechnical CQA Officer, Construction Manager and/or Contractor/Liner Subcontractor in the event of a failed test. The Contractor/Liner Subcontractor's laboratory test results shall be presented to the Geotechnical CQA Officer for comments. 6.2.6 DEFECTS AND REPAIRS 6.2.6.1 Identification All seams and non -seam areas of the VFPE shall be examined by the Geotechnical CQA Monitors for identification of defects, holes, blisters, undispersed raw materials and any sign of contamination by foreign matter. Because light reflected by the VFPE helps to detect defects, the surface of the VFPE shall be clean at the time of examination. The VFPE surface shall be cleaned`"by`the Contractor/Liner Subcontractor if the amount of dust or mud inhibits examination. Each suspect location as identified by the Geotechnical CQA Monitors, both in seaTn andmon-seam-areas,-shall be non-destructively tested using the- methods described herein, as appropriate. Each location which fails the nondestructive testing slaall.,be marked by the...Geotechnical CQA Monitor and then-xaepaixed and re -tested by the Contractor/Liner Subcontractor. Work shall not proceed with any materials that will cover locations that have been repaired until laborator3r-test results with passing values have been obtained. 6.2.6.2 Repair Procedures Any portion of the VFPE with a flaw or which fails a nondestructive or destructive test shall be repaired in accordance with the Specifications. The Geotechnical CQA Monitor shall locate and describe all repairs on the appropriate forms. Repair procedures include: • Patching - used to repair large holes, tears, large panel defects, and destructive sample locations that are less than 25 ft2 in total area. • Extrusion - used to repair relatively small defects in panels and seams. -29- C:\2001-048TINAL COVER CQA.DOC\08/20/01 Geologic Associates
