Possible deviations for masonry

Knowledge of the constructional error is very important for the quality of the building. Especially since it is difficult to achieve the ideal ratio when laying. These parameters are influenced by the qualifications of the masonry and possible non-standard materials and the state of the foundations.

The quality of the brick

Building standards and quality requirements for brick have not changed for decades, which means that with such deviations from the design dimensions, the brick wall will cost you as long as you need it. This means that it has been verified both by calculation and by practice. So, remember:

In order to ensure the solidity and solidity of a building built from building materials, the rules for wall cutting must be followed. Because incorrect (irregular) laying of building materials can cause destruction.

Inspection of brick structures

On all walls of the residential building, a cue in the form of white coats was recorded from inside and outside (figure 1, 2) which does not meet the requirements of SNiP 3.04.01-87 "Insulating and finishing coatings" and GOST 530-2007 "Bricks and stone ceramics, General technical conditions ", according to which" 3.7. Finishing and protective coating on substrates with rust, pouch, grease and bituminous spots is not permitted "and" 5.2.3 Vysols are not permitted on facial products ". "Vysola - water soluble salts that appear on the surface of the burned product in contact with moisture."
High humidity bricks (more than 27.5%), visible wet points on the front wall (Figure 3-5);

How thick should the stitches be in the wall?

The quality and reliability of the brick depends directly on the selected and realized mortar thickness used in longitudinal and vertical joints. This value is placed at the design stage, monitored on each line and checked by measuring the height of the built-in section through 5-6. The deviation from the recommended values ​​results in loss of composition, formation of fragile bonds between the blocks and rapid destruction in the future. Reduction in power is the result of additional stress in compression and bending, and the unequal removal of moisture from the compounds, which is unacceptable.
