Geosynthetics Failure Laboratory Formally Opens
Melbourne, 6 March 2019:  ExcelPlas has opened a failure analysis facility in Melbourne, Australia which will provide failure analyses that support the geomembrane and wider geosynthetics industry in conducting effective and efficient root cause analyses. The aim is to prevent and learn from geosynthetics failures and continue to improve safety, reliability and up-time.  The facility will carry out the crucial initial steps of a failure investigation, which could include visual inspection, non-destructive testing [NDT], destructive testing [DT], representative sampling, cutting of components, etc. The facility will be supported by ExcelPlas’ very experienced team of polymer experts who are able to carry out further analyses, which may include fractography (scanning electron microscopy), mechanical testing, chemical analysis, etc. as well as draw on experience from several 1,000 failure analyses carried out in the ExcelPlas Labs over the past 25 years. The facility consists of a large warehouse to support receiving, inspecting, and storing large geomembrane rolls, GCLs and other failed components, as well as office space and other facilities.  There is much to be gained from geosynthetic manufacturers and end users performing failure investigations and root cause analyses as it provides better insight on why liners, geotextiles and other geosynthetic components have failed and how failures can be prevented in the future, enhancing safety, reliability and saving costs.  For our customers, we routinely conduct incident reports and independent forensic failure analysis of HDPE geomembrane liners, GCLs and other polymeric components. We know first hand that HDPE liner failure can result in loss of containment, environmental spills, loss of production and ultimately in costly litigation and damages. In addition, these failures can cause service interruption, safety concerns and loss of brand credibility. For these reasons, we believe that condition monitoring and failure analysis of geosynthetic liners must be standard practice for the market. We strive to determine an exact cause of failure, and develop remediate, corrective actions to prevent recurrence.
