ASTRA: Gotthard road tunnel, 2nd tube

As part of the preparation of the implementation project, the B+ G was commissioned on 3 May 2016 to clarify the suitability of the excavated material and to assess its suitability for TBM excavation. For this purpose, exploratory drillings from the safety tunnel were carried out and analysed.

Since the end of 2021, B+G has also been acting as aggregate and concrete experts on behalf of the client.

TELT: Tunnel Euralpin Lyon-Turin (84km length)

Since 2021 B+ G supports a consortium for the tender of the material management lot. Based on our experience, the raw material is continuously tested in the construction site's own laboratory.

Concrete tests with sulphate-containing aggregates (produced from tunnel excavation) and special binders were carried out in the Modane intermediate attack on 7 April 2016. Among other things, the sulphate resistance is to be investigated.

Dam Spitallam KWO

The new Spitallam dam in the Bernese Oberland will require around 200,000m3 of concrete. The mass concrete consists of a maximum grain size of 125mm! A gravel plant was built for the production of the aggregates. B+ G supports the client KWO in the quality of raw materials, aggregates and concrete.
