Ground or Conductive Geotextile

Non Conductive Geomembrane


Usage Conditions

SENSOR DDS® MIT Arc Tester can be used on any non-conductive geomembrane like HDPE, LLDPE, PVC,, bituminous liner and other electrically insulating materials.

A grid, test lanes or other acceptable system should be used to ensure that the entire area is tested with the test probe including welds. The SENSOR DDS® MIT Arc Tester probe attachment can be supplied with different shapes and lengths (as required by client).

Testing must be performed on geomembranes that are generally clean and dry. Small non-conductive debris can be present. There needs to be a sufficiently conductive material below the geomembrane being tested (e.g. sand, gcl, soil, clay etc).

For double lining systems comprised of two layers of geomembrane in order to make any electric method feasible a sufficiently conductive layer such as a conductive geotextile, conductive geocomposite, aluminium foil, sand, or any appropriate conductive material shall be installed under the upper / primary geomembrane. Conductive-backed geomembrane can also be used as the upper / primary geomembrane to enable the method.

It is not recommended to use this equipment in wet conditions or during rain / snow fall.

For more information about method principles please see ASTM D7953-14

SENSOR DDS® MIT Arc Tester is the most revolutionary QC device in the world of electrical leak location services. It was developed specially for testing of exposed geomembranes and in accordance with the newly published ASTM D7953 standard.

The SENSOR DDS® MIT Arc Tester is able to precisely locate the holes through the liner including in the welds immediately after installation. The size of the detectable holes starts from less than 0.1mm! In event of a hole, the SENSOR DDS® MIT Arc Tester will alert the user with an internal audio-visual alarm. It is very easy to use and does not require any expensive training unlike other methods. SENSOR DDS® MIT Arc Tester is simply ”plug & play” device. For those who would like an official training certificate issued by Sensor we do offer a one day training course where we can train as many of your operators as required.

It is Important to note that SENSOR DDS® MIT Arc Testers don’t interfere with each other so on one site multiple units can be used at once (refer to device manual). If required, daily productivity can be increased simply by employing more operators so your project will never be late. Our main goal was to bring our clients a QC tool which is more effective, reliable, economical, easy to use and more precise than other commonly used methods including water based systems. We are proud to say that this was achieved in every sense. For more detailed comparison please see the table below. SENSOR DDS® MIT Arc Tester is made in Germany. From first glance you can see and feel the quality of this product which is backed by standard EU warranty.

The main features of 2018 model:

Our SENSOR DDS® MIT Arc Tester can be used everywhere waterproofing is required. For example geomembranes installed at basins, ponds, tanks, leach pads, storm ponds, landfill cells, green and other flat roofs, landfill caps, tunnels, building foundations, canals and other containment facilities.

It is the most technologically advanced QC tool for testing of exposed geomembranes. It is capable of testing exposed non-conductive geomembrane and geomembrane covered with geotextile!

In comparison to the common holiday spark testers our Arc Tester can easily locate a leak in a patch repair.
