Reinforced concrete shirt for strengthening the foundation

Every building’s foundation ensures its strength and stability. Even the strongest foundations, though, are subject to deterioration over time. This may result in structural problems that jeopardize a building’s longevity and safety. The application of a reinforced concrete shirt is one efficient way to strengthen and prolong the life of a foundation.

Around the current foundation, a reinforced concrete shirt serves as a barrier. This extra layer fortifies the foundation and offers more protection from outside forces and environmental elements. It assists in preventing cracks and other types of damage that may develop over time by distributing loads more fairly.

In order to implement a reinforced concrete shirt, the foundation must be surrounded by a layer of concrete that is frequently reinforced with steel bars. When considering other options for foundation repair, this procedure is comparatively simple and may prove to be a more affordable option. Homeowners and builders who want to make sure their structures are secure for many years to come frequently choose it.

Use of a concrete shirt to reinforce the foundation can prove to be a prudent investment, whether one is dealing with an older building or getting ready for future stresses. It is a dependable solution for fortifying foundations because it offers comfort and aids in preserving the structural integrity of the entire building.

What is a Reinforced Concrete Shirt? It"s a method used to strengthen and repair the foundation of a building by adding a layer of reinforced concrete around the existing foundation.
Why Use It? It increases the load-bearing capacity of the foundation, improves its durability, and helps prevent future damage or settling.
Materials Needed Cement, sand, gravel, steel reinforcement bars (rebar), and water.
Steps Involved 1. Clean the existing foundation. 2. Install rebar around the foundation. 3. Mix and pour concrete around the rebar and existing foundation. 4. Allow the concrete to cure properly.
Benefits Provides extra support, prevents cracks, and extends the lifespan of the foundation.

Causes of deformation of the structure

A building’s walls may completely collapse due to foundation subsidence, which would mean the building would be destroyed. A number of analyses of the supporting structures that were destroyed (those specifically related to the foundation and its flaws) are done in order to determine the primary causes of building deformation. Principal causes:

  • Loads. Extension of buildings/floors, installation of massive equipment indoors.
  • Aquifer. If such a layer appears, the pressure on the soil increases and, accordingly, additional pressure is created on the walls of the building. The soil swells, cracks and faults appear.
  • Soil. The soil can change its properties due to the influence of precipitation. Soil changes inevitably lead to deformation of buildings. The soil, depending on its type, can shift at any time. Carefully examine the soil before starting construction, select the necessary materials for the future foundation to ensure stability and safety.
  • Builders" mistakes. Foundations can collapse due to design errors at the very beginning of construction. The depth of the foundation, the small area of ​​the base and other errors can lead to serious damage.
  • Quality. Low quality of materials used in the foundation, as well as the lack of qualifications of the builders.
  • Waterproofing. In case of a violation of waterproofing, the basement ebb system will not be able to function normally.

The estimate for construction work includes a special analysis of potential causes of deformation in order to prevent destruction from the aforementioned factors. This comprises:

  • waterproofing;
  • sand cushion (will help to strengthen the bottom layer);
  • removal of groundwater;
  • work with a reinforced concrete jacket.

Diagnostics of destruction

The primary diagnostic technique involves observing the structure’s distortion, which is how instability is identified and its causes are ultimately discovered. Beacons made of gypsum will be useful here. Fill in the cracks with putty or gypsum, and place a marker with the beacon installation date written on it. Keep an eye on its location and take appropriate action if there are any deviations. An "experiment" of this kind should ideally run for a full year. You can thus easily keep an eye on the outcome.

If you’ve noticed that the beacons’ positions have changed or have deformed, fortify your property with a concrete jacket. Prior to installation, thoroughly examine the structure’s subterranean portions, bearing walls, and any potential damage. Excavate pockets down to the foundation’s depth and then carry out an inspection to verify these parameters.

Installing bridges and keeping an eye on their movement is still advised after some precautions have been taken to avoid destruction. The best time frame is one year. The structure has stabilized if the beacons have not moved from their original locations.

Strengthening the foundation

The primary techniques for fortifying surfaces are:

  • shotcrete;
  • reinforced concrete jacket;
  • bored injection piles;
  • increasing the base of the foundation (expanding the foundation);
  • strengthening with brick.

The most popular and successful technique is the installation of jackets made of reinforced concrete. Actions taken in preparation:

  • disassemble the basement cladding to the highest base of the underground structure;
  • expose the foundation (it is advisable to carry out the process in parts);
  • dig trenches (width – 1 m, length – 3 m);
  • clean the underground part from soil, unstable elements, contaminants;
  • remove cracks, begin their reinforcement;
  • impregnate the surface with a primer. A primer with deep penetration properties is recommended;
  • bury sand and gravel at the bottom of the trench – this will become the basis for the future drainage cushion;
  • drill holes (through), insert ribbed reinforcement there;
  • tie the embedded parts with wire, pick up the wire with iron rods.

One useful and efficient way to increase a building’s stability and lifespan is to reinforce the foundation with concrete shirts. Using this method, a layer of reinforced concrete is wrapped around the foundation to help distribute loads more evenly and provide protection from environmental stresses. In doing so, you not only fortify the current structure but also avert possible problems such as settling and cracks, guaranteeing a more secure and long-lasting foundation for years to come.

Reinforcement of the base

The base of the structure is an extension of its foundation, which is on the ground rather than beneath it. Only once the jacket (first foundation) has completely hardened are actions to fortify the base feasible:

  • Tie horizontal metal rods along the perimeter of your structure to the reinforcement and embedded parts of the above-ground foundation (base).
  • Create formwork along the entire perimeter of the structure. The height of the formwork should be equal to the height of the base, the width is 25 cm.
  • Install vertical panels, fix them with bars from the outside, put them to the upper edge of the formwork.
  • Make crossbars in the formwork. This will help to avoid deformation, curvature of the shape. Fasten the parts of the structure with self-tapping screws.
  • Apply a marker on the wall, it will determine the main points of the lower foundation, along which the base will be built;.
  • Stretch fill level.
  • Prepare a liquid cement mortar (it will penetrate better into recesses and existing cracks).
  • After the mixture has completely hardened, remove the formwork (disassemble or break).
  • Perform a basement drainage, drainage outlet.
  • Decorate the base (if desired). Concrete surfaces can be tiled.

One efficient technique to improve a structure’s stability and longevity is to reinforce the foundation with a reinforced concrete shirt. This technique aids in preventing potential damage brought on by different environmental factors in addition to giving existing foundations additional support. It’s a workable way to prolong the life of older structures.

The procedure includes adding a layer of reinforced concrete to the foundation to increase its strength and protection. This method is particularly helpful for structures that exhibit signs of deterioration or that are situated in high-risk areas for earthquakes and other natural disasters. You can guarantee the longevity and safety of the building by strengthening the foundation.

The versatility of a reinforced concrete shirt is one of its main advantages. It can be customized to meet the unique requirements of various buildings, whether they are residential or commercial. In addition to increasing the foundation’s ability to support weight, the additional reinforcement lowers the likelihood of cracks and other structural problems.

To sum up, strengthening a foundation with a reinforced concrete shirt is a dependable and effective technique. It provides a long-term fix that strengthens a building’s structural integrity, giving building managers and homeowners alike peace of mind. Anyone wishing to preserve and protect their property would be wise to invest in this method.
