Securing the Placo® quarry in Cormeilles-en-Parisis by recycling excavated soil.
For several years now, ECT has been deploying its comprehensive expertise in the backfilling of open-cast quarries to :
define the geotechnical stability of external embankments, modeling their shape and inclination to ensure they are built to the highest standards,
backfill at very great heights (>100 m), using successive level embankments,
organize safe emptying zones on steep slopes.
