In seven months, Soletanche Polska excavated the site.
The bottom of the complex project lies 18 metres below the water table and has a residual water flow rate of 20 cu. Metres per hour across the worksite’s 14,600 sq. metre footprint. To limit water ingress in the absence of a waterproofing layer, Soletanche Bachy’s Polish subsidiary designed and delivered a temporary anchored diaphragm wall. Subsequently, 195,000 cu. metres were dredged under water and a temporary underwater concrete plug was then poured. The plug has a volume of 25,000 cu. Metres (1.5 metres thick, with 914 micropiles to permanently anchor the plug reaching a depth 23 metres). It was poured in seven days without interruption at an average rate of 150 cu. metres per hour.
Respectful of the environment and completed with zero accidents, this project illustrates the expertise of the Soletanche Bachy group.
