East St. Louis Project, St. Louis - Illinois (USA)
BAUER Foundation Corporation (BFC), the US subsidiary of BAUER Spezialtiefbau GmbH, has been commissioned by the U.S. Army Corps of Engineers (USACE), St Louis district with the construction of approx. 570,000 square feet (53,000 m²) of single-phase self-hardening slurry cut-off wall in the existing levee system.
BFC will operate as the General Contractor for the project.
The cut-off wall total length is approx. 4,600 feet (1,400 m) with a maximum depth of almost 143 feet (43.5 m). Excavation will be carried out by both clamshell and cutter through alluvial soils to key panels two feet into the underlining Limestone bedrock.
The project is located on the eastern bank of the Mississippi River, near St. Louis, Missouri.
The cut-off Wall was designed by USACE to mitigate the groundwater seepage phenomenon that risks to undermine the structural stability of the earthen embankment built to contain the river during flooding events.
