Last underwater concrete floor poured!
Early on the morning of 6/09/2023, the last cubic metres of concrete for the underwater concrete floor in the Rottemerentunnel were poured. In total over 122,400 cubic meters of concrete have been poured in the past one and a half year in 33 construction pits. Most of the underwater concrete floor of the 2.2 kilometre long tunnel is reinforced, something that has never been done on this scale before. Hundreds of divers alternated in shifts and worked day and night to complete the job. At the bottom of the water-filled construction pits, the pile heads and sheet piles were cleaned and reinforcement nets were laid, amounting to no less than 14,000 tonnes of steel.
