The white reflective surface of these HDPE geomembranes reduces wrinkles caused by thermal expansion however the white layer is not as well protected against thermal oxidation as the black layer.
Chemists at ExcelPlas have shown that Cracking in the Oxidized White Layer of White Surfaced Geomembrane can propagate into Unoxidised Black Layer

ExcelPlas develops GeoSeamTracker™ – tracking and recording tags for geomembrane welds/seams (New Technology)
The tracking tags which are permanently inserted into the air channel of each geomembrane seam can be encoded with the history of the seam.
The system allows installers and facility owners to retrieve full details relating to the MQA of the liner and the CQA of the seams as well as condition assessment information over the lifetime of the liner.
A handheld reader similar to a metal detector can be used to identify the location and history of each geomembrane seams (even when buried) by walking around the perimeter of the lined installation.
