Restoration of cultural heritage

Construction is an activity that has left a lasting legacy to humanity that we have the opportunity to admire again and again.

Inspired by this very fact, ING-GRAD was founded as a construction company whose activities include specialized works comprised of: restoration and reconstruction of monumental heritage of exceptional historical and artistic significance.

In more than 35 years of work on the restoration and reconstruction of the monumental heritage, we have been using all the advantages of modern construction methods, but also applying unique knowledge based on the techniques, skills and recipes of old crafts.

In the cultural heritage restoration projects, we highlight the following works:

Static restoration

Most buildings of cultural or architectural heritage are brick buildings built of stone or brick wall elements connected with mortar, usually found in poor condition due to their age and inadequate maintenance. Therefore, before the renovation and final arrangement, it is necessary to carry out constructive restoration. The complexity of the historical buildings restoration requires the incompatibility of traditional and new materials and respect for their original existence, which is why the use of reinforced concrete is not recommended. The most favourable technique for repairing and strengthening such constructions has proved to be injection, i.e., stabilizing and closing cracks in damaged walls by injecting special injection compounds, applying reinforced cement or epoxy coatings on one or both sides of the wall, and pre-tensioning the walls.

Did you know?

The arrangement and furnishing of the Veliki Tabor Castle were preceded by its structural rehabilitation, which included static restoration of the stone walls and vaults. The stone structure was stabilized and strengthened by injection with special injection mortars and additionally strengthened by the installation of steel braces, which at the same time secured the building from shakes.

Reconstruction and restoration of wooden roof structures

Roofs of monumental heritage buildings are usually wooden roofs with different types of covering, depending on the tradition of the climate in which the building is located. The reconstruction of such wooden roofs implies the replacement of individual elements or the complete structure with new wood, most often made of Slavonian oak or conifer, and the replacement of the covers.

Did you know?

On the church of Sv. Marko (St. Mark), the symbol of the city of Zagreb, the reconstruction of the wooden roof was carried out with larch wood, and the covering was replaced with a new glazed tile made according to the original photo-geometric drawings of the builder Hermann Bollé. The new tile, like the original one, was made and delivered from Hungary.

Renovation and reconstruction of external and internal elements of the building

The renovation and reconstruction of the building includes the renovation of the external facade, the execution of profiles and stone plastic, the production of wooden joinery and everything that includes the restoration of the historical appearance and original condition. It is done according to conservation guidelines, which is why the restoration and reconstruction of the building is longer and requires specific materials, works and methods of execution.

Did you know?

On the project of the Museum of Slavonia in Osijek, renovation works were carried out on the facade and facade of the building by making lime plaster according to the original recipe. All materials were prepared and produced on the construction site. The specific colour of the facade was achieved with natural pigments obtained from the ash of larch wood.

Craftsmanship works on the restoration of the monumental heritage

After the constructive rehabilitation and external decoration of the building, a series of delicate and demanding craftsmanship works usually follow, which must be carried out in the spirit and tradition of the construction of the climate in which the building is located.

Did you know?

In addition to the fact that the area of the Museum of Sinjska alka is arranged and equipped so that the modern museum and other equipment fit perfectly into the ambience of the old Venetian building, the wooden floor covering in the main hall, where there is a representation of the procession of Sinjska alka in real size, was made with a demanding and interesting technique that evokes the uneven surface of the Sinjska alka track.

Sacred architecture

The Archbishop's palace in Zagreb, Kaptol 31, extends parallel to the Zagreb Cathedral, and is located south of the Cathedral, while the Archbishop's spiritual table is perpendicular to the palace and extends east of the Cathedral. The complex of the Archbishop's palace was built within the ramparts that protected it from the Turkish conquests. The building is a protected cultural property, and the first records of the buildings inside today's Archbishop's palace date back to the 13th century.

After two devastating earthquakes in 2020, the building suffered significant damage to the structure, facade, staircase and roof. The rehabilitation and strengthening of the structure is carried out with new building materials that are compatible with existing, classic materials. The strengthening method is minimally invasive and enables the preservation of the original construction characteristics in the exterior and interior of the building. The works will satisfy an essential condition for the building, which is mechanical stability and resistance.
