Who we are

Anchored in Switzerland and internationally active, WALO is managed as a family business in the 4th and 5th generation. For over 100 years, WALO has focused on the combination of consistency and innovation.


What we do

WALO is active as an innovative total solutions company in all markets of the construction industry. The family-owned company has established itself as a reliable partner in the construction industry and infrastructure projects in Switzerland and worldwide with its decades of experience and the permanent development of sustainable as well as economical solutions.



We have successfully implemented many challenging projects. Therefore, we proudly let our references speak for our work.



Whether residential, industrial, healthcare, outdoor or for sports and leisure facilities - seamless floor coverings have to meet a wide variety of requirements on a permanent basis.



Good buildings and thus satisfied customers require precise construction work. All our employees, from unskilled workers to engineers, play a key role in ensuring that we achieve this goal time and time again.



The Limmattalbahn is one of the most dynamic regions in Switzerland. For further development, an expansion of public transport is necessary.

Project description

The Limmattalbahn is to take over a large part of the future additional traffic and provide optimal access to the Limmattal, which is one of the fastest growing regions in the Zurich area. The Limmattalbahn runs as a fast fine distributor coordinated with the S-Bahn from Zurich-Altstetten to Killwangen. With a total of 27 stops on the 13.4 km long double-track line, Altstetten as well as the communities of Schlieren, Urdorf, Dietikon, Spreitenbach and Killwangen are made accessible and connected. The Limmattalbahn is a meter-gauge railroad operated with bi-directional vehicles. The share of own track is more than 90%.

Special features

The Limmattalbahn was realized in two stages. Stage 1 included the section from Zürich Farbhof to Schlieren Geissweid. Stage 2 includes the section Schlieren Geissweid to Killwangen-Spreitenbach station and the construction of the depot. Track construction work for stage 1 started in May 2018 and was completed at the end of July 2019. As part of the Schlierefäscht festival, the new line could be used for the first time by VBZ streetcars on Saturday, August 31. Since September 2, 2019, the 2-seater streetcar has been running on schedule as far as Schlieren.

Track construction work for stage 2 started in January 2020. Work is being carried out at up to four work sites simultaneously and several intensive phases with three-shift operation are planned. A first one in Badenerstrasse in Dietikon has already been successfully completed in summer 2020. By the end of 2020, track construction work from the Farbhof station to Altstetten station will also be completed.

As in Stage 1, the civil engineering work for the Limmattalbahn is divided into individual lots. This requires intensive coordination and flexible approaches to implementation.

The commissioning of the second stage with connection to Altstetten station is in December 2022.

The entire rail technology for the Limmattalbahn is being planned, supplied, installed and commissioned by four total contractors (TU) Bahntechnik. Walo Bertschinger AG (lead management, technical and commercial management; 75% share) and Carlo Vanoli AG Thalwil (25% share) form the ARGE GOB Limmattalbahn, which has been awarded the contract for the track superstructure lot and is carrying it out. The two engineering firms Basler & Hofmann AG and SNZ Ingenieure und Planer AG were involved as subcontractors for project planning, specialist construction management, surveying and commissioning.
