Dams, like other structures, naturally deteriorate over time. Deterioration opens the way for leakage, which in turn accelerates the deterioration process. Even when structural safety is not threatened, there is an economic loss and negative public opinion perception.  

SIBELON^® geomembrane systems are a permanent solution to stop leakage and provide protection from progressive deterioration. They can be installed in a short time, with minimum disruption of operations and minimum environmental impact.  They can be installed over the whole upstream face of the dam or only on the most critical sections.
