Next Generation Geosynthetic? Inflatable balloons that seal off tunnel portals and protect them from flooding
The New York Times have a nice article about the potential of using inflatable balloons to seal of tunnel portals and protect them from flooding. Of course the challenge is the amount of water pressure that the balloons will need to resist while plugging the tunnel.
There is an ongoing research project directed by Prof. Ever Barbero of West Virginia University funded by the Department of Homeland Security .Read more about this research project here!
If you want more information read about it in the New York Times article.
