Diagnosis of a roadblock

Saint Benoît du Sault dam (36)

Client :          GEOTEC ORLEANS

The Saint Benoit du Sault dam is a 17th century structure that carries the Route Départementale n°1 to cross the river "Le Portefeuille".

It consists of a masonry wall on which a mud embankment rests while a veil of masonry stones covers the upstream facing.

Following the observation of leaks downstream and the presence of fontis on the crest of the structure, Sol Solution was commissioned by Géotec Dijon to carry out a diagnosis of the Saint Benoit du Sault dam with a view to rehabilitation work.

Core drillings at a depth of 13 metres were carried out, as well as internal erosion tests HET, in the laboratory.
