When waterproofing monitoring is required at projects with design where subgrade below geomembrane has got insufficient conductive properties, Sensor leak detection geotextile can be used.
At flat roofs such insufficient conductive layer is represented by therm-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
