Lettarve Port
Extension, France
Often ports require deep water adjacent to quays and berths to accommodate large vessels, the cast-in-place diaphragm wall technique provides a robust, long term solution for the provision of deep water berths for port and harbour works. Diaphragm wall construction has long been a mainstay of Menard Bachy's business activities.
Other techniques used in harbour works are piling (from pontoons or embankments), permanent prestressed anchors and fill consolidation (dynamic compaction, vibroflotation, drains), all are techniques in the Menard Bachy range of skills acquired over several decades of involvement in large domestic and international projects.
Construction projects at ports and airports often involve vast areas. The objectives for ground improvement can include stabilisation of reclaimed fill, increase of surface bearing capacity or an anti-liquefaction treatment (earthquake).
Frequently land, reclaimed for port expansion, is initially wetlands or fully submerged and the reclamation is effected by placing dredged or imported fill materials over such areas. The consequence is that generally the reclaimed area needs treatment to make it fit for purpose; the challenge then becomes the identification of the most economical means to improve vast quantities of soil.
The primary objective for Menard Bachy's engineers is to determine a soil treatment which stabilises the fill and delivers compliance with specified performance requirements.
