Brickwork injection: how it will help and how to do it

Despite the strength and durability of brick walls, problems also occur with them. Injection of masonry often helps to fix them. Our advice site decided to tell you about this way to prevent further destruction of brick walls and extend the life of the entire structure.

Brickwork injection: how it will help and how to do it

Problems with masonry walls can arise for various reasons:

  • Incorrectly calculated the load on the foundation;
  • The roof is leaking, the walls are wet;
  • Shrinkage of the foundation due to the peculiarities of the soil and soil movements;
  • Deformation of beams and floors;
  • Violation of construction technology.

The process of destruction of masonry at the first stage can go unnoticed. And then cracks appear, individual bricks collapse and fall out โ€ฆ We need to urgently take action. In such situations, they often resort to injecting brickwork..

The essence of injection is simple โ€“ a special compound is pumped into the brick wall. It solidifies inside, providing a reinforcing effect, as well as enhancing the insulating properties of the wall. The composition is pumped through specially made holes โ€“ boreholes. The mixture is pumped inward under high pressure through injectors โ€“ thin pipes with packers. To carry out the work, the injection composition itself, injectors, as well as a construction syringe or pump are required.

Important! This method is also used for waterproofing wet areas such as basement walls, tunnels, swimming pools..

For injection of brickwork, the following compositions are used:

  • Methyl acrylate gels. They have excellent adhesion and fluidity, they penetrate well even into the most inaccessible places. But they are used only at the beginning of deformation and destruction of masonry. In case of serious problems they cannot help;
  • Microcement mixtures. Environmentally friendly, durable, can be used even in the case of complex repairs to the lowest row of bricks. However, they freeze for a long time;
  • Polyurethane resins. They have high fluidity, fill cracks well, solve the problem of waterproofing masonry. There are one-component and two-component. Such compositions have practically no drawbacks and are able to cope with a variety of problems with masonry;
  • Epoxy resins. Wobbly structures are literally glued together, reinforcing the entire wall. Strong, do not shrink, but are expensive and harden for a long time;
  • Silicate resins. Created on the basis of liquid glass, durable, do not shrink, and are inexpensive. There are no particular drawbacks. Often, silicate resins are used together with microcement compositions..

The process of repairing and strengthening brickwork by injection looks like this:

  • The external decoration and destroyed parts are removed from the wall, loose cracks expand;
  • The entire surface is washed with water;
  • When water is absorbed into the masonry, holes are made with a diameter of 20 millimeters and a depth of 5 to 25 centimeters, depending on the thickness of the wall. It is convenient to make holes with a puncher. The distance between the holes is no more than 20 centimeters if the repair is carried out throughout the entire masonry. Often, injection is carried out only in the problem area;

Important! Holes are made at an angle of 60 degrees. One crack requires at least two holes.

  • All holes made are moistened to improve adhesion;
  • Tubes are inserted into the holes, they can be fixed on the wall with ordinary cement mortar;
  • The selected composition is pumped into the tubes with a pump or a construction syringe. The pumping process is carried out from the bottom up and from the center of the masonry to the edges;
  • Then the injector tubes are carefully removed;
  • You need to wait for the time specified by the manufacturer of the composition for its complete solidification. Excess mixture is removed, if there are depressions, they are covered with cement mortar;
  • You can proceed to finishing the wall.

As the portal has already written, injection is also used to repair deep cracks in reinforced concrete walls and structures. The method is reliable and already proven. However, coping on your own can be difficult. The service of injecting brickwork costs from 1.4 to 1.9 thousand rubles per running meter, depending on the type of composition used and the complexity of the work.

      Brickwork injection is a method used to reinforce and improve brick structures. It involves injecting a specially formulated epoxy resin into the mortar joints of bricks to increase their strength, stability, and durability. This process helps to prevent further water penetration, stabilize or straighten walls, and enhance the overall integrity of the structure. The necessary steps for proper brickwork injection include thorough cleaning of the brickwork, drilling holes into the mortar joints, injecting the epoxy resin under pressure, allowing it to cure, and finally pointing or repointing the mortar joints. Skilled professionals use specialized equipment and techniques to ensure the injections are carried out accurately and effectively. The process offers several benefits, such as extending the lifespan of the brickwork, reducing the risk of structural damage, and improving the aesthetics of the building.
