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.
Renovation of slipway NDSM
Methods of repair
SealteQ started by dust-free milling of the exposed concrete surface. Subsequently, the surface was cleaned with a pressure of 500 bar. Cleaning the surface is important for repairing the concrete damage. Subsequently, the damage was tapped off, chiselled out and repaired by our specialists using a repair mortar. The steel expansion profiles were also dismantled and replaced. After this, a multi-layer cement-bound levelling system was applied to the Y-slope. Finally, a fully reinforced Triflex Pro – Park system was applied to the slipway. Challenging work because the application of both the levelling layers and the Triflex Pro – Park system was highly weather-dependent. Thanks in part to SealteQ’s work, the NDSM slipway has been renovated and has retained its status as a cultural heritage site.

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.
