The building is a brick utility structure with a gable roof. The external walls are made of white silicate brick. During the visual inspection, typical cracks in the masonry were identified on all facades.
Vertical and stepped cracks along the masonry joints were recorded on all four sides, ranging in length from 1 m to over 2 m and predominantly 2 mm to 5 mm wide, with some showing local openings. The cracks were mainly located near corners and openings (windows, doors), indicating structural concerns related to the building’s engineering design, particularly at corner nodes and load-bearing walls with openings. Considering the nature and scale of the damage, a decision was made to use the Stati-CAL technology, specifically the method of Stati-Bar Ø8 mm spiral anchors, to reinforce/strengthen the walls in the areas with existing cracks.
Our specialists created chases in the masonry, which were then filled with Stati-CAL 30N injection grout. After that, a special Stati-Bar Ø8 mm stainless steel spiral anchor with a unique DNA-like structure was installed. This type of reinforcement allows the load to be distributed along the entire length of the crack and restores the wall’s load-bearing capacity. Unlike rigid metal ties, Stati-Bar does not create new stresses in the masonry. Its flexibility allows it to work together with the natural movements of the structure caused by seasonal and temperature changes.
In total, 40 linear meters of spiral reinforcement were installed over 2 working days
