The Groner-membrane is an inflatable lining which turns any tunnel into a completely hydraulic smooth waterway reducing energy loss losses dramatically.
The durable membrane is subject to a small inner water pressure and "floats" in the surrounding water. The patented design therefore transfers hydraulic forces instead of containing them.
The result is a reliable and durable lining that substantially increases output with an absolutely marginal environmental impact:
- Tunnel friction loss: up to 75 % reduction.
- Installed capacity: may be increased with up to 100 %.
- Power production: 20 % increase can be achieved.
New renewable energy with minimum environmental impact.
