The works carried out on an approx. 99,000m² plot, as part of a consortium with Renard TP (head of consortium), consisted of filling in old underground chalk quarries, using mass earthworks, backfilling, compacting and filling with sand-cement mortar on the edges.
This project was impressive not only in terms of volumes but also efficiency and rates, as the teams exceeded 17,000m3 of grouting over 2 months of production.
These exceptional performances were made possible by using the new continuous, high-rate grout production and mixing plant developed by SAE / AES / SAML and Sefi-Intrafor.
So it was in November that the 10+-person Sefi-Intrafor team completed the final drilling that hadn’t been possible at the start of the worksite last May, meeting the deadlines.
