Sensor introduces DDS MIT for waterless geomembrane arc testing

News, Products | August 30, 2022 | By:

Sensor DDS® MIT technology is 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, and 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 generates an audio-visual warning to the technician, which makes  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.

Advantages of waterless geomembrane arc testing:

  • Cost effective
  • No upfront cost
  • Additional quality control for installation of geomembranes
  • Electronic verification of integrity
  • High voltage DC arc testing device
  • Developed to further strengthen QC of geomembrane
  • Generates an audio-visual alarm when damage is found
  • Verifies the integrity of the entire surface including welds
  • Identifies all damage caused by transit and installation
  • Can detect even the smallest < 0.5mm pinhole damage
  • Protection for the client and the installation contractor
  • No water required to operate
  • One operator can test up to 6000m² per day
  • Zero interference between units
  • Many operators can work simultaneously
  • Minimal training is required
  • Lightweight – the entire kit weighs only 2.5kg

Sensor’s founders invented electronic geomembrane leak detection and location monitoring systems and installed the first system in the late 1980s on a hazardous waste storage site. That first installation is still operational today, confirming continued integrity of the installed geomembrane and protecting the environment from hazardous waste leaks. Sensor’s electronic leak location and detection technology has been successfully deployed to monitor and protect in excess of 17 million square meters of geomembrane liners across a diverse range of structures  in a variety of differing industrial sectors.
