Stormwater Storage

Stormwater holding basins are designed to allow the controlled discharge of large quantities of temporarily stored water.

Given that the lining system is the key element of such structures, particular attention needs to be given to the alternating high and low water levels: long periods of drought pose a significant danger in this connection as any drying-out of the lining system will impair its long-term performance. The problem is readily accommodated by the NaBento® RL-N bentonite mat, which, thanks to its bituminous coating, is particularly resistant to drying-out.
