Every diaphragm wall construction site is different. The excavation depth as well as the width of a diaphragm wall is often a crucial factor.
The prices per square meter for inner-city building sites rise every year; therefore the number of floors to be built into the depth rises as well, in order to achieve best utilization of the site area.
For particularly great depths HÜDIG offers the TOYO armoured pump version DP30-7HD. Diaphragm wall depths of more than 40 meters are no problem for this model. The maximum working depth of the HD version is 120 meters.
