Repairing the base of a brick apartment building may include various works, the list of which may vary depending on the extent of damage and the reasons for its occurrence.
Here are the main methods for repairing the base of a brick building:
Elimination of moisture sources. Installation or restoration of a drainage system to drain rain and groundwater from the foundation. Application of waterproofing materials (for example, bituminous mastics, membranes) on the outer surface of the base.
Repair of cracks and damage. Use of special elastic sealants or cement mortars to fill cracks. In some cases, it may be necessary to install metal corners or other structural elements to strengthen weakened areas.
Replacing damaged bricks. Carefully removing destroyed bricks and cleaning the seams.
Replacing damaged bricks with new ones using high-quality mortar.
Renewal of the base facade. Application of a protective layer of plaster to improve the appearance and protect against moisture. Use of water-repellent paints to protect the surface of the base.
Elimination of biological contaminants. Use of specialized means for removing biological contaminants and subsequent treatment with antiseptics.
Strengthening the foundation. Introduction of special compounds to strengthen the base and eliminate subsidence. In case of serious damage, temporary strengthening with supports may be required until the main work is completed.
The choice of repair method depends on the specific situation, the extent of damage and the available budget. It is also important to take into account the recommendations of specialists and carry out repair work in compliance with all building codes and regulations.
