摘要

Manufacturing data record (MDR) has traditionally been the basis of compliance assessment and approval of geomembrane material for use in construction works. Acceptance of the MDR data has strong reliance on the quality control management following industry recognized international standards. 250,000 m~2 of conductive geomembrane material was approved on the basis of compliant MDR for use in a project in Australia for lining a process water storage dam. The conductive geomembrane material was manufactured with a non-conductive edge to assist with the welding of the material. Frequent seam failures during the installation phase triggered rigorous investigation of the geomembrane material properties. During the process of investigation of the extent of this inconsistency, it was detected that the non-conductive edge of the geomembrane material is under gauge (occasionally 15% or more) and non-compliant with the Technical Specification. Significant investigation and Root Cause Analysis were undertaken by the Designer and the Manufacturer. The investigation detected that the inconsistency is as a result of production anomaly, that has been able to bypass the manufacturer's quality assurance process and possibly applicable to all geomembrane rolls supplied for the project. In order to eliminate the deficiency, all susceptible seams were eliminated.
