Sensor leak detection geotextile should be used in projects where subgrade below geomembrane has insuficiently conductive properties and one time testing of geomembrane is going to be performed (Arc Testing – SENSOR DDS® MIT).
At flat roofs such insufficient conductive subgrade is represented by thermo-isolation (polystyrene, mineral fiber isolation,etc.) which also acts as an electrical isolator. Sensor leak detection geotextile is an alternative replacement of ordinary 300g/m2 non woven geotextile used on roofs what saves additional cost for material and installation.
Our detection geotextile can be used for one-time testing of geomembrane using portable testing devices SENSOR DDS® MIT (when liner is dry and exposed) or SENSOR DDS® Mobile (for covered geomembrane with gravel or soil). However it also can be used for permanent 24/7 geomembrane integrity monitoring in conjunction with SENSOR DDS® CMS
