4.2.6 Wrinkles During placement of materials over the geomembrane, temperature changes or creep may cause wrinkles to develop in the geomembrane. Any wrinkles which can fold over must be repaired either by cutting out excess material or, if possible, by allowing the geomembrane to contract by temperature reduction. In no case can material be placed over the geomembrane which could result in the geomembrane folding. The QA/QC Inspector must monitor geomembrane for wrinkles and notify the,QA/QC Manager and Geosynthetics Contractor is wrinkles are being covered by soil. The QA/QC Inspector is then responsible for documenting corrective action to remove the wrinkles. 4.2.7 Folded Material All folded geomembrane must be removed. 4.2.8 Geomembrane Anchor Trench The geomembrane anchor trench should be left open until seaming is completed. Expansion and contraction of the geomembrane should be accounted for in the liner placement. The anchor trench should be filled in the morning when temperatures are coolest to reduce bridging of the geomembrane. 4.2.9 Leak Location Testing The QA/QC Consultant will perform leak location testing on the HDPE geomembrane twice during construction of the cell. The first test shall be performed following geomembrane installation.The second test shall be performed following placement of the granular drainage material and protective operations layer over the geomembrane. The requirements for the leak location testing are included in Attachment A. 4.3 Geotextiles 4.3.1 Delivery During delivery of geotextiles the QA/QC Inspector will: • Verify that equipment used to unload the rolls will not damage the geotextile. • Verify that rolls are wrapped in impermeable and opaque protective covers. • Verify that care is used to unload the rolls. • Verify that all documentation required by the Specifications has been received.
