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 and water reservoirs.
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.
Geophysical survey
By using a complex of geoelectrical methods, magnetometry, thermometry and gravimetry BHF environmental offers cooperation in solving problems within the following fields:
environmental geology and engineering (site investigation for new landfills, electrical leak detection tests, geological survey and monitoring of old landfills, detection and delineation of contaminant plumes,...)
engineering geology (site and ground investigation for all types of structures, location of old mines and cavities, detection and definition of bedrock, detection of heterogenities/faults in soil and rock formations, survey of landslide areas,)
hydrogeology (location of water well, geotermal springs, definition of water protection zones, definition of groundwater flow direction, location of leaks from reservoirs, inspection of dikes,...)
corrosion survey
location of old ammunition
archaeological survey (location of shallow buried objects in the ground or in structures such as walls, pavements, cellar floors)
mineral prospecting
