Shurf is a universal way of testing the wear of the foundation
Shurf is a procedure that helpsto examine the foundation without serious damage, to know its depth, thickness and width. Such works are simply irreplaceable in conditions of dense city buildings.
Description of the technology
Very often, if the integrity of the base is violatedat home, you need to know the degree of damage and determine what repair methods can be used in this situation. Often, drilling wells is contraindicated, because there is a risk of complete destruction of the foundation.
A pier is a deep pit that breaks out along the outer or inner side of the house. With its help, you can determine all the details of interest and perform a qualitative restoration.
Choice of location for the hole
The place for examination is selected strictlyindividually for each building. Most often, priority is given to areas where clear damage is visible. Also, a foundation pit can be made in areas that do not require repair. This is necessary in order to draw up a plan for the execution of work and to understand what are the points of support.
Shurf is a procedure that is carried out with the purpose of prevention, in order to notice and eliminate the damage in time. Therefore, in addition to critical situations, it is carried out in the following cases:
- In places with high loads.
- If a multi-storey house has several sections in it, then each of them is checked.
- On sites where additional supports are planned to be installed.
Number of holes
This indicator depends on the reason for the work and the technology of building the foundation.
- If the base is of a monolithic or ribbon type, then several pits are pulled out, at a distance of not more than one meter from each other.
- For inspection, the length of gaps between pits increases to 3-4 meters.
- In the event that there is a risk of a drawdown of the building, exploration pits are made bilaterial.
Considering that the pit is a pit, which is excavated for the purpose of conducting diagnostic work, the following indicators can be detected with its help:
- Depth of the underground part of the foundation.
- Accurate information on the size of the substrate.
- The presence of various damages.
- Strengthening the load on specific sites.
- Also with the help of a hole, various samples are taken, on the basis of which it is possible to determine the strength of the foundation, its composition and the quality of materials used in the construction.
This procedure is very useful in the modern world, because it allows you to identify and correct various defects in time, preventing premature destruction of buildings.
