Dams - Underwater repair and rehabilitation

De-watering of reservoirs is not always feasible due to project constraints (e.g. water reservoir for water supply, and loss of power source for hydro-electric schemes) or because emptying and refilling of the reservoir can cause problems to the structure. In these cases, underwater installation is necessary. SIBELON® geomembrane systems can be installed underwater at any depth, on the entire surface or on critical parts only.

SIBELON® geomembrane systems for underwater installation avoid loss of service because of outage, loss of water, and downtime for emptying and refilling of the reservoir. They have reduced impact on the environment, no impact on local communities, fish hatcheries, recreational areas etc.
