Challenges during Diaphragm wall construction

by Michel Bock, COWI




This presentation focusses on case studies of significant challenges which can be encountered during the construction of diaphragm walls (D-Walls) in Singapore and globally. D-Walls are underground structural elements commonly used as earth retention systems, permanent foundation walls and groundwater barriers for large and deep underground structures. We will discuss current solutions and suggestions for enhanced control and supervision during the construction of D-Walls.


Michel Bock is a leading geotechnical specialist in COWI with more than 30 years of experience in supervision of complex geotechnical works for large infrastructure projects. This includes supervision of diaphragm wall and bored secant pile construction, supervision and analysis of micropiles construction and testing, design and supervision of groundwater control systems and grouting (permeation grouting, jet grouting, compensation grouting, soil mixing).

Michel was lead geotechnical specialist   for the COWI Singapore team delivering the detailed design of DTSS2 T0-09 in Singapore. He led the design and supervision of the groundwater control and grouting of this challenging project. His extensive experience on other COWI projects include, Hong Kong Zhuhai Macau Link, China , Third Runvway, Chek Lap Kok  Airport, Hong Kong, Canakkale 1915 Bridge, Turkey, second Ishwar Gupta bridge, India, Red Line North Metro, Qatar and Cityringen Metro, Denmark.
