Disadvantages related to safety factors:
These defects appear as a result of neglecting cracks and surface cracks, or water leaks in the sewage pipes of the building, which increases the humidity; It can also appear when building a number of floors in violation, and this leads to exceeding the percentage of load allocated to the building.

Restoration for the purpose of renovation:
This type is resorted to when the property owner desires to re-design the building's exterior facades, and does not involve interfering with the repair of the building's internal structure.
Restoration for the purpose of consolidation:
Specialists resort to the use of reinforcement restoration in the case of structural repairs for fear of the building collapsing over its inhabitants, such as: strengthening the reinforced concrete foundations of the building, increasing several floors, and also strengthening floors and inclined areas.

What are the methods of restoration?
The degrees of danger to which the building is exposed vary, and accordingly, the methods used to repair different types of cracks differ, and these methods include:
Restoration of building foundations:
This method depends on increasing the loading on the ground through the concrete block used, and the aim of this method is to reinforce and strengthen the lower bases of the buildings.
It is carried out through the method of drilling and then cleaning the concrete surfaces, followed by the application of a layer of protection to avoid iron rust.
Restoration of building columns:
The dilapidated columns are restored by adding some layers of at least 10 cm thickness of reinforced concrete or metal, after making sure that the concrete surface is cleaned and dried well.
Bridge and knot repair:
Bridge restoration is based on increasing the concrete thickness from the bottom of the building and from above, then adding a layer of iron bars to increase the concrete's durability.
Methods of renovating residential buildings
What are the steps to be taken before renovating residential buildings?
The owner of the property goes to the district administration concerned with obtaining licenses for restoration and construction, then submits an application for a license to restore the residential building, with the following documents attached:
A copy of the identity card of the property owner, a copy of the building license, a copy of the report of the engineer or the consulting office stating the need to restore the building, a copy of the executive plan of the restoration process, in addition to the measurements and specifications used
After that, the building must be subjected to an examination by the competent engineer to perform several procedures before starting the restoration process, namely:
First: Make a follow-up system for the extent of the crack or crack emerging.
Secondly: Make drawings of the condition of the building and compare it with the original drawings, implementation steps and a soil analysis report.
Third: Make some reports on the current status of the building, the proposed plan for repairs and the restoration methods to be followed.

How is the process of renovating residential buildings?
Before starting the repair process, the location of the crack must be determined, the steps needed to treat it, and then the materials needed to fill this crack must be prepared. Then we follow these steps:
1- Treating cracks and cracks
Repairing surface cracks: It is treated by drying the damaged surfaces, then using a chemical that prevents water leaks. Restoration of deep and wide cracks: This is done by ensuring the drying of the concrete surfaces, then expanding the cracks and pouring a low-viscosity chemical or cement material. Building cracks restoration: The crack is restructured in a V-shape, then the concrete surfaces are cleaned and parts of the dilapidated buildings are removed, and at the end a special type of mortar is added and the outer surface is painted.
2- Reinforcement and repair of structural elements
Moisture diffusion treatment: the damaged areas are disposed of, then the reinforced iron is cleaned to protect it from rust. Finally, it is ensured that the damaged area is well dried and covered with cement materials. Floor subsidence treatment: the demolition remains are removed and the area is refilled with a dense layer of clean sand, water, and Stabilizing the soil, until the floors return to their normal position, Treating the tendencies of towers or balconies: It is treated by supporting it from the bottom with a layer of cement and iron, then installing steel nails for support.
