The Most Accurate Dipole Testing Method
SENSOR DDS® MOBILE technology takes quality control of covered geomembrane liners to a whole new level of accuracy and reliability. Using an approach where a generated electric current follows moisture passing through damaged areas of the liner while mobile sensors on top of the covering layer measure the resulting current flow to identify potential leaks and damage.
SENSOR DDS® MOBILE In Action

Roof leak detection
The SENSOR DDS® MOBILE is designed to accurately test different kinds of roofs for leaks and damage, including flat roofs, green roofs and brown roofs. 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 liquid) the operable depth is unlimited. (click on the heading for more info)

Tailing dam leak detection
The SENSOR DDS® MOBILE is highly effective when used to test tailing dams, leach pads and other ponds used in the mining industry for leaks that can contaminate groundwater and lead to huge financial costs from product loss and environmental damage. (click on the heading for more info)

Landfill leak detection
From our experience, most damage is identified after installation of the protective drainage layer onto the geomembrane, using our SENSOR DDS® MOBILE it is possible to nip potential toxic leaks in the bud and perform repairs quickly and for a low cost on the affected areas.

Advantages of using the SENSOR DDS® MOBILE on your projects
Quick, accurate and reliable.
This method requires no permanent site installation, it is a speedy way to ensure no damage remains after installation of a geomembrane and its protective layer.
Lightweight, easy to use
One Sensor technician can survey up to 10 000m² of geomembrane per day. We can engage up to five technicians and survey up to 50 000m² per day, so your project will always be on time.
Low cost, saves you money
The cost of Sensor’s geomembrane integrity control is minimal when compared to the potential cost of repairs and the risk of environmental damage and product loss post-completion.
SENSOR DDS® Mobile is a dipole survey used for integrity testing of covered geomembranes. It can be used on liners covered with variety of materials like soil, gravel, sand, liquids, etc. Among the most used applications are:
- Green Roofs
- Mining Leach Pad
- Mining Tailing dams
- Lakes
- Balconies
- Water storage tanks
- Industry lagoons
- Sewage tanks
- Landfills
- Landfill capping
- Leachate lagoons
- Dams
Examples of damage detected by the SENSOR DDS® MOBILE. Even under 900mm thick gravel cover!
Progression of the testing process using the SENSOR DDS® MOBILE; identifying damage, excavating damage, marking damage, repairing damage, replacing the cover layer
