Strengthening the foundations of buildings

During construction and operation, the foundation can be exposed to various factors: moisture, temperature differences, additional loads, vibrations, etc. The consequences can be devastating to the building. If you diagnose the problem in time and eliminate it by strengthening and strengthening the foundation, the building will be able to serve for many years.

Signs of foundation problems:

It is worth paying attention to the state of the base of the building if:

• During visual inspection of the foundation, deformed and destroyed areas are visible.

• Cracks began to appear on the decoration, walls inside the room and the basement.

• There is a partial collapse of the structure.

Reasons for the destruction of the concrete base of the structure:

• During construction, the loads that the foundation will experience were incorrectly calculated;

• Constant or seasonal impact of natural or man-made factors: washing with groundwater, low temperatures, ice, etc.

• Absence of monitoring of building and foundation condition, preparation of base and soil for additional loads.

Situations where foundation base reinforcement is required:

In more detail

• It is planned to build a new building on an existing concrete base.
•  The foundation load is expected to increase due to the addition of additional floors or levels.
• There are signs of deformation and destruction of concrete at the base of the structure.

What can be done?

To strengthen the pile foundation

The foundation of piles is considered one of the most durable and reliable ways to secure the building on the ground, but this option may also require strengthening. The most popular are considered: the installation of cages around collapsing supports, the reinforcement of the foundation with new piles, the addition of drilling and injection supports.

To strengthen the tape foundation

Such a base demonstrates excellent stability and strength characteristics with minimal construction material costs. It is used in the construction of small, low-rise buildings and buildings. You can increase the bearing capacity of the tape base using the following techniques: for finely-buried bases, the method of reinforcing concrete casting ("concrete jacket") is used. For thickening, you can use a concrete clip, bracing walls using metal corners or channels. Additionally strengthen with piles, special spraying (torcretting), use crossed reinforced concrete ribbons, etc.

To strengthen the monolithic foundation

If the soil under this type of foundation is mobile, the structure can be covered. To strengthen the foundation of the house, you can use piles, drive pipes and other additional support elements.
