ELD - Geomembrane Leak Detection System
Our measurement method ensures full surface and reliable monitoring of the geomembrane. The measurements are largely independent of the load or ongoing work above the sealing system. Even during ongoing construction , we can conduct precise analyses without compromising on safety or accuracy. Any damages to the geomembrane are precisely located using our electric leak detection..
The necessary cable technology is integrated during the construction of the sealing system, ensuring smooth operation.
Optionally, the measurement on the measuring cables can be automatically conducted via a web server. This innovative option not only increases the efficiency of monitoring but also allows for timely evaluation of measurement results through a user-friendly platform. With this advanced technology, we offer not only the highest precision in sealing monitoring but also a convenient and contemporary handling of measurement processes.
It is an electrical measurement method. An electrical signal is generated on one side of the geomembrane, while a measurement is simultaneously conducted on the other side. Since the geomembrane itself is electrically insulating, the signal can only be detected on the measurement side in case of damage.
Measurement cables with measuring electrodesThe durability of the installed cable technology is very high, spanning several decades. The chemical stability is extremely high, due to the choosen materials, even in challenging environments. Cables and measurement points are extremely robust and adapted to the stresses in underground construction. The cables have an elongation capability of over 10% and can thus withstand local settlements without damage.
The measuring cables of the system are installed before the installation of the geo membrane. These are unrolled in parallel at intervals of several meters.
Due to the complete prefabrication of the cables, this work can also be carried out by the installer of the geomembrane or the construction company without disrupting the construction process.
The system can be operated in different modes according to requirements. Single measurements can be conducted as part of the preventive maintenance program. For stricter standards, measurements can be performed permanently via a web server allowing faster reaction times.
The results are clear and can be presented transparently and comprehensibly. Leakages are made visible and precisely located.
Due to the electrical measurement principle, the geomembrane is monitored full-surface for the smallest leaks.
The accuracy of the localization is significantly better than the chosen electrode spacing due to interpolation.
Regardless of the size of the leakage or damage to the geomembrane, our highly precise measurement method allows for the exact localization of even small cracks. Through this approach, we ensure that small defects are discovered fast and can be addressed to ensure the integrity of the sealing and minimize potential environmental impacts, solution losses and stability risks.
