Electrical Leak Detection Surveys

The geco system

BHF Environmental has specialised in electrical leak detection surveys since 1994.

To detect and locate leaks in plastic membranes, the company uses the geco system. This application of geoelectrics is widely used as an effective tool in the process of Construction Quality Assurance in many countries, mostly for landfill applications, water reservoirs, and other lined liquid containments.

With our geco system the locating of any perforating damage to the geomembrane is rapid, accurate and cost effective. The system utilises the insulating properties of geomembranes. An electric current is applied across the protective layer placed over the membrane. Subsequently, the electric potential is mapped over the inspected area. Anomalies in electric field indicate the geomembrane damage.
