Dead Sea Works

The longest diaphragm walls in the world

In 2013, thyssenkrupp Infrastructure announced the securing of a major contract with the company Dead Sea Works Ltd. (DSW) in Israel. The project involved the delivery of sheet steel piles for sealing an 18 kilometers long dam that is even capable of withstanding earthquakes. The sheet steel wall, which has been installed down to a depth of more than 30 meters, effectively prevents the dam from becoming permeated or undermined.

The steel wall covers an area of 540,000 square meters – equivalent to the size of 75 football fields. In 2014, thyssenkrupp Infrastructure reported a follow-up order of 900 tons of sheet steel piles. These extra-long piles were specially transported overnight along a winding road almost 1,000 meters in altitude downwards to the level of the Dead Sea, where the piles were subsequently driven 28 meters deep into the seabed.

These gigantic sheet steel components not only meet all of the required standards, some of them have been additionally fitted with signal transmitters, a technology that provides information during installation as to whether the locking mechanisms of the sheet steel piles have connected as planned, or become detached.
