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.
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.
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.
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.

City of Samobor

Castels, Palaces and Fortresses
The noble old town of Samobor was built by supporters of King Otokar II on Tepec hill in the period from 1260 to 1264 above the Samobor market place, in order to strengthen the old border at that place. The floor plan of the city is irregular and divided, and consists of three parts, of which the central part with the city core is the oldest. In the south-eastern part of the core there is also a tall defensive tower, the only substantial remnant of Otokar's oldest construction phase, and it distinguishes this town from the other two noble towns in the vicinity, Okić and Lipovac, of which it is larger. Next to this tower is a semi-circular tower with an interesting chapel of St. Anne from the third decade of the 16th century on the first floor of the three-story tower. Over time, the core expands to the north into an elongated trapezoidal courtyard surrounded by a strong defensive wall with a pentagonal battery tower at the ends. On the south side is the last built three-story house. More significant reconstructions took place in the third decade of the 16th century, and the largest in the 17th and 18th centuries, and then a palace courtyard was formed in the core with facades of open porches, and the interior was richly furnished. At the end of the 18th century, the owners left the city.
As part of the project of consolidation and presentation of the Old Town of Samobor, renovation works were carried out on the walls of the chapel. Considering the monumental features and difficult working conditions due to the complexity of vertical and horizontal transport, the project was very demanding. The construction of the stone wall, with a structure equal to its original state, required the engagement of high-quality masters of old trades - craftsmen. Cleaned stone from the collapse, white cement and slaked lime were used in the construction.
