Restoration of Baroque halls at the Blue Stone Castle for puppet theater, regional history
and creative workshops for children and youth

The ground floor of the East Wing and the entrance area of the chapel and the gallery of the chapel have recently been restored and are in good construction and technical condition. Over the last hundred years, any reconstruction works on the castle always addressed the needs and purpose of the actual owners. About 70 years ago, the truss and the roofing were completely replaced. The sanitary facilities were added to the building in a rather thoughtless manner, they were simply attached to the main courtyard façade. Parts of the manor house, which were last restored at the beginning or middle of the last century, currently show a range of construction and technical problems.

Below we will briefly describe the most urgent issues:
The structural elements of long-term service life (except for the binder and external plasters of the perimeter walls, which are in a poor condition), do not show any defects or excessive wear. The biggest construction-technical problem is the other and added parts of the building, in particular the roof, which is in an emergency state. The roofing of the North Wing and the West Wing is at the end of its service life, it is fragile and unstable in shape. Except for the roof of the East Wing, the entire roofing must be urgently replaced. The tinsmith works of the roof are not tight and are locally corroded. The roof leaks in several places. The roofing of the North Wing of the manor is currently under replacement. The overall condition of the truss is good, damages are mainly local. The electrical installation and the internal sanitary installations are in an emergency condition. Due to a recent emergency, the horizontal part of the drain pipes was locally repaired, however the interior parts of the drain pipes are still leaking. The heating system does not work in most parts of the building. The external fillings of the openings, the floors, the technical facilities, and their installations in un-renovated parts of the building are in an emergency condition. The fillings of the windows and exterior doors are obsolete. The exterior parts of the fillings have no functional protective surface treatment. The wood frame of the outer windows is cracked and deformed in many places, the wings of the windows leak. The wooden floors, around the windows, are in poor condition, damaged by abrasion and local leakage, as well as by unsuitable surface treatments based on technical oils. A relatively large percentage of the floors must be replaced or repaired. The external plasters are damaged. The probes showed that external plasters are made of cement. From the viewpoint of building physics, they form a high diffusion resistance that causes air-tightness of the perimeter walls. Moisture has regularly precipitated under the external plasters, which gradually caused chemical decomposition of the wall binder and degradation of the masonry. In the interiors of the ground floor and basement of the North Wing and West Wing, the plaster around the plinths is locally moist and, in some places, it peels off from the surface. The presence of aggressive salts causing the degradation of plasters and masonry was confirmed. The basement floors and parts of the ground floor are wet. Excessive moisture in the substructure is a major problem for the manor in general. The walls have no functional waterproofing, they transport ground moisture rising up from the foundations to the interior. The surface rainwater from the courtyard during heavy rains supplies the masonry with a lot of water. The paved areas of the courtyard are mostly made of concrete. The surface of the concrete is weathered and crushed by long-term exposure to the elements. The entrance baroque bridge is in an emergency state. Its supporting arches are excessively moist and saline. The protective surface of the bridge does not fulfill its purpose, it is leaking. The vaults are damaged by rainwater, which flows through the leaks in the bridge deck surface into the core of the structure.
