Waterless geomembrane testing
Waterless geomembrane testing

Sensor DDS® MIT technology was developed specifically for the testing and quality control of exposed geomembranes including synthetic waterproofing membranes, liners and asphalt systems.

It is applied to the exposed face of the liner directly after installation. The system electronically verifies the integrity of the entire surface including the welds enabling the elimination of all damage including pinholes.

When the damage is encountered the equipment will generate an audio-visual warning to the Technician making the equipment simple to use.

All geomembrane liner installations should be thoroughly tested to ensure complete integrity exists, prior to the placement of any covering media over the liner. Geomembranes put into service with existing damage will cause the early deterioration of the protection they can offer.

The standard quality control systems normally offered during liner installation concentrate solely on the welds and as such these controls will miss damage to the liner in mid-sheet areas.

Clients can be sure that the installer has provided a clean installation, whilst the installer is protected from claims for damage caused to the liner that occurs after the test date.
