The building at the intersection of Koningin Marialaan and Juliana van Stolberglaan in the Bezuidenhout district of The Hague must make way for the construction of four residential towers containing 128 rental apartments. Contractor Ballast Nedam was troubled by a lot of water in the construction pit. The dam wall ditches appeared to be leaking. Grondinjectie Nederland sealed the leaks so that construction could take place in a dry and safe cofferdam.
