Detection of leaks in geomembranes is a crucial process in surface coatings engineering, specially en construction work where impermeability of structures such as pool, residue deposits and dumps is mandatory. The importance of detecting a leak comes from preventing damages to the environment or soil contamination.

Dipolar method

With this technique we apply a different in potential between the upper section (filling) and the lower one (terrain), where the geomembrane behaves like an electric insulator. The leaks present themselves as perturbances en the potential field of the filling. By doing potential measurements on the surface we are able to locate the leaks.

Dry Lance

Dry Lance is a system of geoelectric detection used for exposed geomembranes. The electric insulating property of geomembranes allows for localization of perforations within itself. With a range of detection of damages lower than half a millimeter, its a quick and efficient to detect leaks in geomembranes.
With this method the possibility of leaks or anomalies to stay hidden after applying the material layer (solid or liquid) on the geomembrane is significantly lowered, avoiding need for repairs in the future.
