SENSOR DDS® MIT is a unique product developed by Sensor capitalising on our experiences with geomembrane integrity testing over the last 24 years.

We have been providing exposed geomembrane testing services using SENSOR DDS® MIT for some over 15 years and we have already surveyed many million square metres of geomembrane.

SENSOR DDS® MIT is developed according to ASTM D7953

This year we have decided to offer our clients even more flexibility and ability to conduct their own surveys using our SENSOR DDS® MIT equipment. We now sell 3 versions of SENSOR DDS® MIT. Standard model suitable for small and large areas; a light version used mostly on slopes due to its light weight; and an XL version for sites with limited personal access where technician can reach up to 6m from the floor or down from an elevated position. Please see the table below:

The benefits of SENSOR DDS® MIT:

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


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.
