Securing an active open-cast quarry

Securing the Sibelco® quarry in Crépy-en-Valois by recycling excavated soil.

Thanks to its experience in backfilling quarries, ECT adapts its activity to the operating conditions laid down in the prefectoral authorization: extraction progress, quality of materials, required compaction. ECT manages the complete traceability of the flow of materials entering the site (grid plan), as well as the quality of the materials used for backfilling.

ECT’s intervention is part of a dynamic of joint activity, through :

• adoption of quarry safety procedures
• anticipating and adapting the backfill phasing to the quarry’s extraction activity
