The Bühlgraben bridge replacement in Sigriswil is a project of particular importance for the region. The old Bühlgraben bridge from 1933 connected the village with the hamlet of Tschingel for almost nine decades and crossed the deeply cut ditch. It was a familiar part of everyday life and a important link. However, cracks and wear and tear made a new construction unavoidable in order to ensure safety and future of this connection.
Here, our concrete specialists from the Pegrila AG contribute their expertise. For us, it was not just a technical project, but also a contribution to an infrastructure that is indispensable for the people in the region.
Precision for a new bridge
To ensure that the new bridge can withstand the challenges of everyday life as well as the demands of the future, we rely on the highest quality and innovative materials:
+Installation of sloping concrete as a stable base
+Sealing UHPFRC layer with around 4 m³ of material
+Completion with approx. 3 m³ UHFB split matrix as a resistant final coating
The result is a 133 m² bridge surface that combines durability and state-of-the-art concrete technology.
Cooperation as a success factor
Such projects can only succeed as a team. Together with Sägesser AG, Sika AG, Maier Ingenieure AG, Kissling + Zbinden AG and our subsidiary Prima Sol The result was a solution that is both technically convincing and does justice to the special location in Sigriswil.
Values that carry
The Bühlgraben bridge replacement project shows how we at Weiss+Appetito, together with our specialists from Pegrila, are putting innovative concrete technologies into practice. UHPC and Splittmatrix stand for durability, safety and quality in the construction industry.
With the new Bühlgraben Bridge, we are proud to have created a connection that not only binds places together, but also people - in the middle of a region that stands for tradition, nature and stability.
