E. Failed Weld Procedures. I. Follow these procedures when there is a destructive test failure. Procedures apply when test failure is determined by the QA/QC CONSULTANT, the GEOSYNTHETICS CONTRACTOR,or by field tensiometer. Follow one of the following two options: a. First Option. • Reconstruct the seam between any two passing test locations. The GEOSYNTHETIC'S CONTRACTOR can not perform the repair by extrusion welding the flap. b. Second Option. • Trace the weld at least 10 feet minimum in both directions from the location of the failed test, or to the end of the weld. • Obtain a small sample at both locations for an additional field test. • If these additional test samples pass field tests, then take laboratory samples. • If the laboratory samples pass, then reconstruct the weld or cap between the two test sample locations that bracket the failed test location. • If any sample fails,then repeat the process to establish the zone in which the weld must be reconstructed. F. Acceptable Welded Seams. 1. Bracketed by two locations from which samples have passed destructive tests. 2. For reconstructed seams exceeding 50 feet, a sample taken from within the reconstructed weld passes destructive testing. 3. Whenever a sample fails, provide additional testing for seams that were welded by the same welder and welding apparatus or welded during the same time shift. G. Seams That Cannot Be Non-Destructively Tested. Perform the following: 1. If the weld is accessible to testing equipment prior to final installation, non-destructively test the weld prior to final installation. 2. If the weld cannot be tested prior to final installation,cap strip the weld. The welding and cap-stripping operations must be observed by the QA/QC CONSULTANT and GEOSYNTHETICS CONTRACTOR for uniformity and completeness.
