Probably, having been in Moscow and St. Petersburg, many people noticed that some residents prefer to say "curb", while others - "curb". But regardless of the city, the curb and the curb are completely different concepts. Some ignore such names and simply call it "side stone". But there are people who ask the question: "Curb: what is it?".
Origin of curb
To understand in more detail why such different names, it is necessary to turn to the origins of history. Even in Ancient Russia, during the construction of white-stone churches, bricks were laid in such a way that the outer side of the wall had an individual ornament. To achieve this result, the brick layer was laid at an angle - with an edge outward. And from this method came the name "curb". Based on what was read above, people should no longer have the question: "Curb: what is it?".
For the first time, the curb was mentioned in the law "On measures to strengthen control over the state of external improvement of the city of St. Petersburg." It mentions that sidewalks with an increased density of pedestrian traffic should be equipped with a curb. The curb should not exceed the level of the pavement.
Curb: what is it
The curb is a kind of separator between the sidewalk and the roadway, which are on the same level. It can be made of bricks that are in a vertical position. It can also be made of solid concrete blocks. A curb is a small fence between a sidewalk, lawn or road.
Often granite can serve as a material for a curb. For example, in St. Petersburg, this is a fairly common phenomenon. It is present along all the embankments and on some old streets. The main advantages of this material are durability, high resistance to moisture and temperature extremes, to mechanical stress. The appearance of the material also plays an important role. Products from it significantly transform the streets of the city. But the only downside is its cost. Therefore, not in every city you can observe granite curbs. From this it should be concluded that the curb is not just the protection of pedestrians from vehicles, but also a kind of decoration of city streets.
Technology for the manufacture of curbs and borders
Today, there are not many varieties of curbs and curbs on the market. The most high-quality manufacturing technology is considered to be semi-dry vibrocompression technology. On the modern market there are two types of this fence: plastic and concrete. The main advantage of the first type is its invisibility. But there is a significant drawback - weakdesign. And therefore it is used as a fence between small footpaths and a lawn. Curbs made of concrete are made using the technology of vibrocasting and vibrocompression. But the quality of products using vibrocasting technology leaves much to be desired: they have an uneven surface and shape. It is very strange that many people still claim that the curb is a curb. Sometimes a reinforced concrete structure is used in technology for the strength of a product, but this fact does not allow making the structure truly strong and durable. Practice shows that when these curbs are used as a fence, they begin to crumble and collapse, and after a certain period of time they completely become unusable. And the curb is a means of protection that should have a long service life.
And therefore the best solution is to use concrete curbs, which are made using the vibrocompression method. Unlike the rest, these products have a more durable design and have a lower cost. The service life is on average 8-10 years. It is noteworthy that over the years their quality remains unchanged.
Concrete is the most durable material
As for curbs, products made of concrete and manufactured using the vibropressing or vibrocasting method mainly prevail. They are designed to protect the pedestrian sidewalk from the highway with a large flow of cars. Installed on a base covered with rubble.
Self-laying curbs
It is not necessary to use special equipment for laying curbs and curbs. This can be done independently. Marking is done on the site where the curb will be installed. It is very important that the marking lines are parallel to each other. Then a not too deep trench is dug and sand is poured to the bottom, everything is leveled and compacted. Then cement mortar is poured and a side stone is installed on it. After the solution hardens, the trench is covered with soil. The curb is not only a means of protection, but also a decoration of a garden or garden plot.
