Probably, having been in Moscow and St. Petersburg, many 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?".
The origin of the 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, brick was laid so that the outer side of the wall had an individual ornament. To achieve this result, the brick layer was laid at an angle - outward with the edge. And from this method came the name "curb." Based on the 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 having an increased density of pedestrian traffic should be equipped with a curb. The curb should not exceed the level of paving.
Curb: what is it
The border 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 upright. It can also be made of solid concrete blocks. A curb is a small fence between the sidewalk, lawn or road.
Often granite can serve as a material for a curb. For example, in St. Petersburg this is a fairly common occurrence. It is present along all the promenades and on some ancient 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 a large role. Products from it significantly transform the streets of the city. But the only drawback is its cost. Therefore, far from every city you can observe granite curbs. From this it is worth concluding that the curb is not just protecting pedestrians from vehicles, but also a kind of decoration of city streets.
The technology of manufacturing curbs and borders
Today, there are not very many varieties of curbs and borders on the market. The most high-quality manufacturing technology is considered to be semi-dry vibrocompression technology. In 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 - a weak design. And therefore it is used as a fence between small footpaths and a lawn. Concrete curbs are made using the technology of vibrocasting and vibrocompression. But the quality of products using vibration casting 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 even this fact does not allow making the structure truly strong and durable. Practice shows that when using these curbs as a fence, they begin to crumble and collapse, and after a certain period of time they become completely worthless. A curb is a means of protection that should have a long service life.
And therefore, the optimal solution is the use of concrete curbs, which are manufactured by the method of vibropressing. Unlike the others, these products have a more solid construction and have a lower cost. The service life is an average of 8-10 years. It is noteworthy that over the years, their quality remains unchanged.
Concrete is the most durable material
As for borders, mainly products made of concrete and made by the method of vibropressing or vibrocasting predominate. They are designed to protect the pedestrian sidewalk from the highway with a large flow of cars. Are established on the basis covered with crushed stone.
Self-laying curbs
For laying curbs and borders, it is not necessary to use special equipment. This can be done independently. On the site where the border will be installed, marking is done. It is very important that the marking lines are parallel to each other. Further, a not too deep trench digs and sand falls into 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 thrown with soil. The curb is not only a means of protection, but also the decoration of a garden or garden.
