Floors, historical buildings and mansions that cannot show the desired performance under the static loads of the buildings, building floors affected by earthquake and landslide needs to be strengthened.

Grounds that are determined to be weak during pre-construction studies are strengthened using various materials and methods such as grouting, jet-grouting, stone columns, bored piles and mini piles. Which method to use is decided according to factors such as the structure of the ground, the size of the area, its depth, groundwater condition, environmental factors, and cost.

Special precautions should be taken for possible problems on the ground in structures to be built on soft grounds. On grounds with a risk of liquefaction, the bearing capacity of the ground is increased with improvement techniques.

In reinforcement projects of structures built according to old specifications, the foundation is made suitable for the new load-bearing elements. In order for the foundation to work properly, the ground must also be consolidated. The new load-bearing elements added to the building system cannot carry the vertical loads of the building without moving the existing foundations carrying the building. In order for the foundation to carry a load, the ground needs the thrust force. In such cases, contact injection is made under the newly added foundations so that the foundation and the ground can work together as a system.
