Tunnel plug

For enclosing an underground mine or the entrance or end of a tunnel, we have developed an inflatable tunnel plug made of heat resistant materials.

A special product from Liberty Gasturbine Holland is an inflatable tunnel plug with which a tunnel entrance or exit can be closed in just a few minutes.

In principle, one or more plug (s) is available for each tunnel, making a permanent installation possible in the tunnel. In case of a calamity, for example, only a button needs to be pressed to seal of  the tunnel. All shapes and models are available
