A clear case for specialists.

In 2010, PORR was contracted to complete the preservation and securing of a 100m high, fissured rock face above the Axenstrasse and the railway line between Brunnen SZ and Flüelen UR. This project provided PORR's specialist teams with a unique challenge: works had to be completed with the aid of a 15-storey scaffold, and certain materials had to be air-lifted to the site by helicopter. 

In this way, PORR succeeded in installing rock anchors over a distance of 500m, and fitting 700m2 of steel mesh netting, to provide lasting protection from rockfalls to the traffic passing beneath.
