Tunnelling and renovating tunnels

Precision engineering in rock – expertise underground.

Innovative solutions for demanding underground construction projects

WALO has been building and renovating challenging tunnels and adits for over 50 years. This involves bringing our core areas of expertise in trackwork, road construction and civil engineering to bear on conventional tunnelling, ranging from drilling and blasting to pipe roofing. Our versatility makes us a sought-after partner for complex, hybrid projects where multiple specialist disciplines overlap.


From constructing new traffic and supply facilities to renovating existing structures, our decades of experience, seasoned teams and courage to break new ground mean that we achieve robust solutions, even under the most demanding of geological conditions.

Our services at a glance


Constructing traffic tunnels

We shine the light at the end of the tunnel.

Constructing traffic tunnels presents significant challenges for the company performing the work in terms of the large cross-sections being excavated. To build long traffic tunnels in as brief a time as possible, WALO increasingly relies on mechanical excavation methods, in addition to conventional techniques, in the form of tunnel boring machines. Thanks to our combination of technical expertise, innovative methods and high quality standards, we deliver carefully considered solutions that meet today’s requirements and safety standards for tunnelling.
