Traditionally, on the second weekend of September, the doors of thousands of monuments across the Netherlands open for Open Monument Day. In honor of these monuments, we are highlighting several projects our SealteQ specialists have worked on in recent years. Renovating and maintaining monuments requires highly specialized expertise—knowledge that SealteQ has in abundance thanks to our many years of experience in concrete and steel preservation.
Open monument day: monument projects highlighted
The Erasmushuis in Rotterdam
Specialists from our SealteQ West branch carried out concrete restoration on the facades of the monumental Erasmushuis in Rotterdam. As one of the few buildings, it survived the bombing during the Second World War. Located on the Coolsingel, in the heart of the city, the project posed challenges not only due to its monumental status but also in terms of logistics.
The Scheveningen Lighthouse
The completion of the works on this exceptional monument dates back to late 2019. In the meantime, we updated the Scheveningen lighthouse in 2021, as we do in our role as maintenance contractor. A distinctive aspect of this national monument was the presence of paint layers containing hexavalent chromium (Chromium-6). As specialists in the safe removal of Chromium-6, it was a fantastic assignment to execute.
Welding Shed at the NDSM Wharf in Amsterdam
Also known as the cathedral of the NDSM wharf in Amsterdam: the welding shed. When the shipyard was still operational, various components were welded together here to form ships. SealteQ Ivacon’s specialists restored the concrete at several locations on this national monument.
The Hagestein Weir Complex
The Hagestein weir complex is one of three weir complexes on the Nederrijn and Lek that SealteQ renovated. Architect Wouter Hamdorff designed the futuristic-looking Hagestein in the 1950s. It is now—unique among the three complexes—a designated monument. In a special cofferdam, our specialists welded the weir’s sector gate under water.
