Understanding on what basis is your building will save you money and nerves

Cracks are common, especially in homes that are over 20 years old.And although many people watch cracks in their walls, but they do not know why they appeared there.Cracks in the walls are developing over time as the foundation of the house moves.When this happens, the situation is not allowed by itself - the cracks will continue to increase.

However, it is extremely rare, a house with serious cracks in the walls can ultimately be destroyed: the design always gives us a time to correct the situation.The more crack or the faster it develops, the more quickly it is necessary to make a decision on this issue.

Seasonal fluctuations in humidity and temperature in soils make the walls crack

Seasonal changes are the most common causes of soil movement, which, in turn, cause cracks in the walls. When the rain begins, the excess of water causes the land to swell, and when the warm weather occurs, the earth is compressed again when dries. The most important thing is to be done if there are cracks in your walls - it is to test the water disposal from the designs: there is no breakthroughs of a watering, storm or sewer tube (in other words of leaks under the design itself), as water around the house can "help" the foundation .

Know your type of base soil

Within the framework of the draft cracks in the walls, you will need to find out what type of soil is built by your home, as it affects the change in the water level and as a foundation shifts over time.

Contact geological engineer or geologist engineer, which can inform what kind of soil is typical of your area.Keep in mind that their recommendations are common, and that in this area can be soil, which is usually called "backfilling".To get a consultation, specifically for your site, you will need to hire a geotechnology engineer or an engineering company (service) to explore soil samples from your area or plot.

In general, there are five types of soils - rock, sandy, clay, or or peat. The most common in Russia is sand and clay. The sandy foundation creates less problems with the foundation, because water can flow freely through the ground, helping to maintain the foundation stable. If in the house built on a sandy basis, there is a serious or developing crack in the wall, it is important to act quickly, as it is a significant sign that nearby is a broken water supply, sewer or storm tube. The first thing you have to do in this case is to cause plumbing.

Clay soils, on the other hand, can be very "reactive", which means that they change their specific volume and shift when the humidity level changes, forcing the base to be easily swell or compressed.This makes the building more susceptible to seasonal movement.For houses built on clay soils, unfortunately, cracks in the walls are a seasonal matter, and therefore they regularly pay attention.
