Cut-off wall work on the Dead Sea

The Dead Sea is rich in potash, which is extracted using earth basins covering an area of 112 km² at the southern end of the Dead Sea. The salt water introduced into the basins evaporates, leaving behind the sought-after raw material. What makes this project unique: the basins are located roughly 400 m below sea level and thus at the world’s lowest place on land. To seal off the earth basins with an area of 112 km² which had become permeable, our specialist foundation engineering team showed what they are capable of: A total of 336,000 m² of cut-off wall were executed using two cutters over a length of 13 km: and this was achieved in the Jordanian desert, under harsh weather conditions and in an extremely saline environment. A masterpiece of organization and mechanical engineering under extreme conditions.
