Is it a curb or a curb?

Probably, having visited Moscow and St. Petersburg, many noticed that some residents prefer to say "curb", and others - "curb". But regardless of the city, the curb and curb are absolutely different concepts. Some ignore such names and call it simply "side stone". But there are people who ask the question: "Curb: what is it?".

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, when building white-stone churches, brick was 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 - an edge to the outside. And from this method there was a name "curb". Based on the above read, people now should not have a question: "Curb: what is it?".

For the first time, the curb was mentioned in the law "On Measures to Enhance Control over the Condition of the External Improvement of the City of St. Petersburg". It mentions that sidewalks, which have 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 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 in an upright position. It can also be made of concrete cast-in-one blocks. A curb is a small fence between a sidewalk, a lawn or a road.

Often, the material for the curb can serve as granite. For example, in St. Petersburg this is a fairly common phenomenon. It is present along all embankments and on some ancient streets. The main advantages of such material are durability, high resistance to moisture and temperature differences, to mechanical influences. Also, the appearance of the material plays an important role. Products from it significantly transform the streets of the city. But the only drawback is its cost. Therefore, not every city can see the curbs of granite. From this it is worth to conclude that the curb is not just the protection of pedestrians from vehicles, but also a kind of decoration of city streets.

Manufacturing technology of curbs and borders

To date, the market is not very many varieties of curbs and curbs. The most high-quality manufacturing technology is considered the technology of semi-dry vibrocompression. In the modern market there are two types of this fencing: 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 pedestrian paths and lawn. Curbs made of concrete are manufactured using the technology of vibration and vibrocompression. But the quality of products with the use of vibration technology leaves much to be desired: they have an uneven surface and shape. It's very strange that many people still say that the curb is a curb. Sometimes for the strength of the product in technology, reinforced concrete construction is used, but this fact does not allow to make the construction truly solid and durable. Practice shows that when using curb data as a fence, they begin to crumble and collapse, and after a certain period of time they completely deteriorate. A curb is a means of protection, which should have a long service life.

And therefore, the optimal solution is the use of concrete curbs, which are manufactured by the method of vibration pressing. Unlike the rest, these products have a more robust construction 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 - the most durable material

As for the curbs, in general, products made of concrete and manufactured using the method of vibration pressing or vibration are predominant. They are designed to protect the pedestrian sidewalk from the highway with a large flow of machines. Installed on a base covered with rubble.

Self-paving curbs

For laying curbs and curbs, it is not necessary to use special equipment. You can do it yourself. A marking is done on the site where the curb will be installed. It is very important that the markup lines are parallel to each other. Further digging is not too deep trench and the bottom is filled with sand, everything is leveled and tamped. Then the grout is poured and the side stone is set on it. After the solution has solidified, the trench is filled with soil. Porebrik is not only a means of protection, but also an ornament of a garden or an infield.
