Menard has been chosen for the « bulk excavation and ground improvement works » as part of the Aubagne LRT maintenance centre.
In order to improve the soil in place, made of gravelly backfilling materials and sandy silts, Menard used the stone columns technique. Made of calcareous material, these columns does not involve any pollution risk towards the Huveaune River nearby.
The deadlines for this jobsite were very short (one month and a half for the implementation of 15,000 lm of columns). Hence, two stone columns rigs and one pre-drilling rig were used.
