SENSOR DDS® MOBILE technology is designed to inspect the integrity of covered membranes / liners / asphalt irrespective of covering type (e.g. liquids, soil, gravel, etc.).

In this version of SENSOR DDS® technology no permanent components are installed on site, electrical sources are temporarily placed near the area to be tested and the sensors are carried to each grid location where measurements are taken.

Waterproofing methods such as asphalt or plastic liners are often covered with a variety of materials following their installation in many different applications.

Experience is critical Technicians must differentiate between environmental / geological influences and anomalies that are as a result of damage. All Sensor technicians are highly experienced and backed by Sensor's 20-years of accumulated know-how.

The use of SENSOR DDS® MOBILE is limited by the thickness of covering above the liner, which must be no greater than 900mm. Where the liner is submerged (water / toxic liquor) the operable depth is unlimited.


The benefits of SENSOR DDS® Mobile:

  • Transferred responsibility – Sensor takes responsibility for geomembrane integrity issuing a certificate accordingly, taking responsibility and therefore reducing your liability.
  • Low cost – The cost Sensor’s geomembrane integrity control is trivial when compared with the potential cost repairs and risk of consequential damages post-completion.
  • No installation needed – This method requires no permanent site installation, it is a very quick and reliable way to control quality to ensure no damage remains after installation of a geomembrane and its protective layer.
  • No material limitations – SENSOR DDS®  Mobile system works on any type of naturally conductive material such as sand, concrete, water, gravel etc. whatever your material selection for the protective layer.
  • Flexibility – One Sensor technician can control 10 000m² of the geomembrane per day.  We can engage up to five technicians and can therefore survey 50 000m² per day, so your project will never be late.
