Quoted When quality and trust are the benchmarks of a good working philosophy, very few can match the LVJ Group.
The Genaflexstore® is a closed water storage system which forms a sealed unit through the integration of the tank lining and the floating sheet. A closed water storage system is best solution for algae growth and water contamination, as external influence on the water quality is no longer possible. Its simple construction means the GenaFlexstore® can be installed quickly and easily. Lead-through can be fitted through a waterproof manhole. The use of high quality reinforced and UV-resistant material gives a long life span and integrated system rules out lining damage from flapping. This makes the system particularly suitable for export and for the storage of clean drinking water.
