Target of the investigation was to perform a leak detection survey in the liner seal of a storage basin for gypsum water. The HDPE liner, with a thickness of 1.5 mm, was installed in 2010 over an area of 24,000m². The water depth was between 5.5 and 6.5 m.
The tight/untight measurements were carried out from a pontoon, with four sensors being lowered into the water from the edges of the pontoon to the surface of the liner. The measurements were executed in a roll-along mode. 940 measuring positions were surveyed, in blocks of 25 m each.
