The Arcade in The Hague is a cemetery with monumental protection status.
The backside of The Arcade is pointed towards the sun and so always warm. The frontside, on which the graves are positioned and where most of the plastered surfaces are, is always shaded and so cold. This side suffered from rising damp and from heavy formation of condensation.
In 2007/ 2008 the plastered surfaces were restored with KÖSTER Restoration Plaster and the pillars made of natural stone were protected with KÖSTER Polysil TG 500 in order to stop salt efflorescence.
