For almost 20 years, I have specialized in excavating works in areas of difficult access and mountain. Almost every job requires new creative solutions, which I can achieve for you in a clean and fast way thanks to my experience, taking into account the necessary safety

In the construction of rock pipelines, new challenges are constantly encountered to install pipelines safely and effectively. The crossings of natural waterways are not rare. To avoid the difficult transport of the pipe coating material, the existing material is sifted directly into the yard with the excavator and installed as a coating.

The pipes were installed through the lake in various pipeline projects for the basic infrastructure of the region. Here, for example, anchors for the electric cable that now runs along the lake bed from Spiez to Hünibach. The cables are also buried in the connection points on the shores, to avoid damage caused by the ships. Walls of shore, piers, canals for boats and harbour facilities are other areas of application for which they are ideally equipped.

Almost impossible outcomes require unconventional solutions. This work scaffolding allowed to perform the pointing work of a pressurized cast iron pipeline. Pressure ducts require the most direct routes possible.

In the nature reserve of Weissenau - Unterseen, I built a total of five decks and mouths with a design of the almost natural shoreline. The walk on the lake was so redeveloped for the local recreation area and the flat shore was returned to the amphibians.

Work on the high mountain soil requires great attention in handling the nearby terrain, to avoid unnecessary damage to the poor vegetation. The wise use of walking excavators in these delicate areas helps to leave as few permanent traces as possible in the...
