Dead Sea: 55,000 tons of material for world’s biggest diaphragm wall

Dead Sea Works Ltd. (Beer Sheva/Israel) has awarded thyssenkrupp GfT Bautechnik GmbH (Essen/Germany) a major contract to seal a dam in the southern Dead Sea. The contract includes the delivery of 55,000 metric tons of material: roughly 38,000 tons of sheet piles and around 17,000 tons of pipe with welded-on corner profiles.

Dead Sea Works Ltd. mines table salt, bromine and other salts from the Dead Sea, one of the world's richest mineral deposits. The already completed dam regulates the water level in the mining area. The sealing measures are intended to prevent the dam from being undercut by seawater.

The deep ground is not suitable for mechanical driving work, so the sheet piles and pipe will be "sunk” by their own weight into a specially prepared trench over a length of 18 kilometers. This will create one of the world's biggest diaphragm wall with inserted sheet pile wall.

Shipments from Bremerhaven in Germany to the Israeli sea ports of Ashdod or Haifa have already started. Deliveries for the project are scheduled for completion at the end of 2012.


thyssenkrupp GfT Bautechnik specializes in civil engineering, offering an integrated range of machinery and equipment backed by customer-oriented services. Pile driving advice, structural analyses, driving and anchoring plans, customer service and spare parts complete the picture, making the company a leading system supplier in maritime and specialized civil engineering.
