Sensor and system for monitoring integrity of a waterproofing system or membrane

A geomembrane integrity monitoring system comprises control means, two geomembranes and a plurality of sensors installed between the geomembranes,

• wherein the sensors are electrically isolated from each other and in electrical communication to the control means;
• wherein the sensors have a sheet form, each sensor having an area;
• wherein the control means is adapted to identify a specified zone of the geomembranes which has been breached by detecting a triggering of a single one of the sensors adjacent to the breach, wherein the zone corresponds to the area of the triggered sensor;
• wherein the control means is adapted to detect the triggering of the single one of the sensors by detecting the presence of an electrical current that flows between the single one of the sensors and ground and that is caused by moisture entering the space between the two geomembranes and contacting the single one of the sensors;
• and
• wherein the sensors are formed from a mesh material.
