Heritage

Heritage comes in many forms. While we traditionally think of historic buildings and monuments, recent years have seen much greater focus on our industrial heritage. Restoring it demands not only the requisite knowledge of materials and associated repair techniques, but also meticulous attention to preserving the object's original appearance.

Because we cannot compromise on structural performance for user safety, preserving the original texture often adds complexity and calls for considerable additional craftsmanship from our repair technicians. We use materials that are frequently tailored specifically to the object or component. In some cases, the tools themselves are custom-made to replicate profiles and similar details with exacting accuracy.

Large-scale concrete renovation Coking Plant Maastricht

SealteQ South has performed a large-scale concrete renovation at the historic Coking Plant on the Cabergerweg in Maastricht. The 1912 building is one of the oldest industrial national heritage sites in the Netherlands and was originally part of the municipal gasworks, designed by architect Jan Gerko Wiebenga.

Basement sealing at Princessehof Ceramics Museum

One of the great things about our work is the variety of locations we get to visit. For example, we are currently working in the beautiful building of the Princessehof National Museum of Ceramics, right in the historic city center of Leeuwarden.

Open monument day: monument projects highlighted

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.

Welding shed of national monument NDSM renovated

Commissioned by BMB Ontwikkeling and Regiobouw, SealteQ carried out various concrete repairs to the welding hall of the NDSM national heritage site. This preserves its status as cultural heritage.

Renovation of Scheveningen lighthouse completed

After the completion of the lighthouse on Vlieland, the Scheveningen lighthouse was also delivered by SealteQ to Rijkswaterstaat. The renovation work was halted for a long time due to the discovery of Chromium-6 in the old coating of the lighthouse. The work, which started in the summer of 2018, was supposed to be completed in October but was only resumed in May 2019. However, the Scheveningen lighthouse was not the only lighthouse where Chromium-6 was found. Chromium-6 was also discovered in the old coating of four other lighthouses treated by SealteQ. The lighthouses in Burgh Haamstede, Egmond aan Zee, and Noordwijk were all further investigated for Chromium-6. As a result, work on these lighthouses was also halted to eliminate health risks.

Air watch tower Warfhuizen

SealteQ is carrying out work commissioned by Brands Bouw en Onderhoud B.V. on the air observation tower near Warfhuizen.

Renovation of slipway NDSM

SealteQ was recently commissioned to renovate the Y-slope of the former NDSM shipyard. NDSM was a shipyard that existed between 1894 and 1978. The Y-slope was renovated in part by SealteQ to be put back into use as a festival location after 3 years. With a view over the Amsterdam skyline on the banks of the IJ, the location can rightly be called a beautiful place for a festival.

Consolidation Lighthouse Island

Following the renovation of Fort Island Pampus, SealteQ's expertise was requested for the consolidation of Vuurtoreneiland (Lighthouse Island). Approximately 3 years ago, Staatsbosbeheer (the Dutch Forestry Commission) approached the market for the preservation and exploitation of this cultural heritage site. Entrepreneurs B. Boswijk and S. Overeinder, with the technical support of SealteQ, won this market consultation.
