Redevelopment and extension of a waste disposal site

Cournon d'Auvergne (63)

Contracting authority :          CLERMONT AUVERGNE METROPOLE

Sol Solution was commissioned by Clermont Auvergne Métropole to carry out the geotechnical studies required for the redevelopment and extension of the Cournon d'Auvergne waste collection centre (installation of supports between the quays, a waste sorting building and platforms for skips).

The general stability of the current site was checked, as the existing landfill was placed at the head of an embankment more than 10 metres high.

A total of 10 pressuremeter and destructive bores, 14 shovel bores, 7 penetrometer bores, 1 piezometer and numerous laboratory tests were carried out.

These boreholes and tests made it possible to dimension the foundations of the future supports for the quays, buildings, the foundations of the platforms under the skips as well as the structures of the heavy roadways.

Sol Solution followed the foundation excavations and the materials used to build the roads.
