REMOVAL OF GROUT AT A DEPTH OF 40 METRES

In order to create sufficient water pressure at this depth, this assignment required a custom solution. On a special ship from Boskalis, we transported two linked hydrodemolition units to the construction site. Together, they could provide a water pressure of 1600 bar and a volume of 330 litres per minute. Then, using various diving crews in continuous shifts, we removed the grout with a pressure strength of 170 N/mm². This assignment is a great example of the added value of our consultation and the input of our client when trying to overcome technical hydrodemolition challenges
