Strengthening of building foundations – Increasing the bearing capacity of building foundations

With time, the house foundation loses its bearing capacity, which can lead to an emergency state of the building. Therefore, in the process of the house reconstruction and repair, special attention is paid to the foundation strengthening. GeoResin provides services associated with strengthening the old house foundation using innovative technologies of geopolymer injection.

When the foundation should be repaired

From the moment of erection, there are many destructive factors affecting the building foundation, both natural and anthropogenic.

Natural factors include:

  • · groundwater level fluctuations;
  • · soil suffusion;
  • · seismic activity, etc.

Among the anthropogenic it is worth noting:

  • · accidents of water communications;
  • · loads on the building foundation beyond project basis;
  • · low-quality building materials used in construction;
  • · construction or earthwork operations nearby;
  • · vibrations caused by construction machinery or heavy vehicles.

This gradually leads to the appearance of cracks in the foundation and walls, which in turn makes the building unusable. You can prevent such consequences by strengthening the building foundation in proper time.

When the old house foundation is repaired and strengthened:

  • · during the new building construction on the foundation of a previously built, already destroyed house;
  • · in the case when it is required to strengthen the base and increase its bearing capacity (when building up new floors, installing heavy equipment, etc.);
  • · during subsidence and changes in the properties of the foundation soils;
  • · when external signs of damage to the foundation appear (cracks, subsidence, signs of deformation of the external or internal finish, doorways distortions, etc.);
  • · emergency condition of the building.

Any work on the foundation reconstruction always begins with its technical examination by a specialist. It allows you to find out what kind of design problems need to be solved in the repair process, and come up with a competent engineering solution.

Ways to strengthen the buildings foundations

Today, there are several methods of strengthening bases and foundations that will help protect your home or commercial premises from destruction. The most common of them are:

1. Injection method.

The injection technology is based on the use of polymer resins. This is one of the most effective and fastest ways to strengthen the house foundation without too much noise and dust. The technology comes to the polymer resins injection into the soil base or foundation, which, expanding, completely fill all the voids and displace water. Due to this, the base is compacted, its bearing capacity increases, the foundation returns to its original position. The technology can be implemented in various ways. GeoResin performs soil injection works under its own brand GeoResin Deep Stabilization and GeoResin Slab Lifting.

2. Cementation method

If the soil at the construction site does not meet the requirements, and the building must be erected on this site, then artificial foundations are fixed up. One of the ways to artificially strengthen the soil is cementing, which is carried out by injecting liquid cement mortar or cement milk into the soil through pipes, which, hardening in the soil pores, give it a rock-like structure.

3. Strengthening the house foundation using bored piles.

Bored piles are widely used to strengthen the foundation of a residential building. From the land surface and from the floor level of the first floor or basement, they drill vertically and obliquely, through the existing foundation of the borehole until it reaches the stiff soil. After drilling is completed, a rebar cage is lowered into the borehole and a cement mortar is served through the injection tubes. The resulting piles resemble the tree roots, most of the load is transferred on.

4. Strengthening with reinforced concrete holders.

This method is also most often used to strengthen the foundation. The principle of technology is to expand the base along the outer perimeter. The foundation is strengthened with a reinforcing mesh, formwork is installed, after which a concrete mixture is poured between the mesh and the formwork.

Benefits of working with us

The Georesin company provides a full range of services to strengthen the foundation of a private house and commercial premises at an affordable price. In our work, we use the geopolymer injection technology – the best modern solutions for strengthening and reinforcing foundations and base soils.

Principles of our work:

  • · thorough diagnostics of the object;
  • · individual design solutions;
  • · compliance with established deadlines.

The unique methods of GeoResin, developed by our specialists over many years of practice, allow us to perform all the work as quickly as possible, silently, without the need to vacate the premises and stop activities. We use environmentally friendly materials in our work, and we do it with care for the environment.

Stages of work to strengthen the foundation

The first stage of work to restore the bearing capacity of the foundation is an expert assessment of the building’s technical condition:

  • · the state of the foundation and back-up structures;
  • · the existence and condition of waterproofing;
  • · the depth and other parameters of the foundation;
  • · collection of loads affecting the base;
  • · characteristics of the base soil and the degree of its compaction;
  • · finding the causes of damage to foundations and subsidence.

The design documentation of the building and reports on previous surveys or repairs are also studied.

The next stage is design. The engineering solution for strengthening the foundation is carried out on the basis of the data obtained during the survey. At the same stage, design documentation is drawn up, which includes the operational procedure at the construction site and a list of building materials used.

The final stage are the building and construction works. At this stage, specialists can carry out the following work types:

  • · strengthening the base soil and foundation;
  • · expansion the foundation bed or an increase in its location depth;
  • · changing the type of foundation;
  • · full or partial replacement of the base soil and foundation.

If you have reached this section, you care about the future of your property. By getting help from qualified professionals in good time, you will save a lot of time and money.

The first step in preserving a building that is prone to collapse is to have the building surveyed by professionals. This will help you avoid making rash or poorly-planned decisions as to what to do in order to stop the process.

GeoResin specialists will come on site and determine the type of foundation deformation and find out the reasons for it. Depending on the data they will make the necessary calculations and determine what actions to take to halt the building destruction and what is the best method of foundation stabilization.

Based on the received information, you can make a balanced decision on which of the three directions to take:

  • 01 Continue to monitor the dynamics of destruction with the help of professional instruments, defining yourself a «point of no return».
  • 02 Develop a draft solution, taking into account structural, financial and «life» constraints, and implement it.
  • 03 Apply for an alternative solution on the basis of the survey to a third party.

REASONS LEADING TO THE NEED TO STRENGTHEN THE FOUNDATION:

  • Not properly compacted base
  • Additional new structural loads
  • Technogenic breakdowns and accidents of engineering communications
  • Regular fluctuations in the groundwater level and soil temperature
  • Excavation or piling works nearby
  • Structural differences in foundations within the same building
  • Regular exposure to vibrations
  • Nonhomogeneous foundation within the same building

QUESTIONS THAT GEORESIN WILL ANSWER:

  • What is going on with the house or structure in general?
  • What caused the cracks or deformations in the structure?
  • Is there any point in waiting for improvements or changes and what kind of changes?
  • Can we get by with face-lift?
  • What will happen if nothing is done?
  • Will «store-bought» or «do-it-yourself» solutions help?
  • Can a «familiar foreman» solve the problem?
  • Is it possible, and how, to slow down or stop the process of destruction?
  • Is it possible to get everything back as before? what are the options?
  • When is it better and cheaper to start solving the problem? is it possible not to resolve it right away?
  • How much does it cost to solve the problem and what are the conditions for implementation?
  • What can be done for x hryvnias?
