Stability of the Payerne abbatiale

The Abbatiale of Payernethe largest Romanesque church in Switzerland, was built in the 11th century and showed cracks, inclinations and subsidence after more than 1000 years. These problems were solved by transverse stresses caused by the Romanesque vaults. In order to restore the stability, slightly inclined Tension cable integrated into the pillars of the side aisles and anchored up to 10 metres deep in the ground. The tension of the cables generated forces that stabilised the transverse weaknesses of the church.

The Enertec Engineering AG already delivered in 2016 Anchor load cells to monitor the tensioning cables. In 2024, we will also have a automatic data logger supplied and installed to ensure continuous monitoring of the anchor forces. The 2M ingénierie civile SA analyses the data.

With our technologies, we have made a significant contribution to securing this unique structure and supported its long-term stability.
