Granite curbs - enviable luxury on the streets

general perception curbs on our roads

Familiar to all citizens separator pedestrian sidewalk and the roadway has different names.In many northern regions it is called the curb, somewhere in the other regions - curbs.But taken and "gostirovannoe" during the time of the Union of the name of the separation of stone - "border" or curb.It is made from natural or artificial stone.

The main functions of curbs should include not only a symbol, but also to ensure the physical boundaries of the inner and outer road Zoning: pavements (sidewalks), traffic islands, portions of soil with plants and trees, roadways, etc.

For this even standardized its height, on the average, the requirements it set in the range of 10 cm. Thus, along with other facilities improvement of roads, increased safety and convenience of pedestrians and vehicles.They serve as a kind of stops for covering pedestrian and roadway.

However, given the operating conditions, curbs can be subjected to a variety of influences, includingmechanically sufficiently great destructive power, the necessity of their subsequent repair or complete replacement.It is known that road works are always very expensive, why and from the point of view of economic expediency of granite curb - the best option curbs.

Granite curbs - a few words about the characteristics

production of high quality granite stones, for example, a popular border GP-1, requires industrial equipment.Naturally, carefully cut from the array of high-quality natural granite block sizes 0,3h0,15h0,7 meters, will cost a bit more expensive than the spitting image of the reinforced concrete the same stone.

necessary to remember and has become so common and popular because of the low cost manufacturing techniques stones and paving slabs methods dry pressing.Is this an alternative to the natural qualities?

is necessary to take into account that the cast block service life of reinforced concrete officially estimated periods of up to two decades.A blocks, obtained by dry pressing, are even less, and rare "live" up to five years, having crumbled appearance and creating a risk of movement.

Therefore undoubted advantages, including in terms of operating efficiency, has already referred to the granite curb the GP-1.Obviously, it has virtually no alternative but to use a variant in the central part of cities and in places where the most heavy traffic, guaranteeing conservation operation aesthetic qualities and appearance.

If the above board granite stone is used mainly to separate the carriageways of roads and streets, the design of the pedestrian part (branch flower beds, lawns and sidewalks, etc.) is more suitable Granite curbs SE-4, manufactured by industrial enterprisesfor this purpose the same equipment.

Standard dimensions of the unit are reduced in proportion and up 0,2h0,1h0,7 meters.Like its "big" brother, this border has an unlimited service life, very durable and aesthetic.

Gres - enviable alternative to natural granite

Speaking of granite materials, it is necessary to remember that these unique stones nowhere else in the solar system do not occur, and this "know-how" of our planet.But the industry has mastered the production of artificial granite, called stoneware.

This type of material is not enough in what concedes, moreover, in some ways superior to natural granite.If the product of an array of natural stones often cut out, adhering to defined tolerances, the manufacturing blocks of granite can be formed initially by raw material-pressing.

Thus, if we can get by pressure and high temperature firing porcelain tiles, border of it has a predetermined size of the geometry, repeatable high accuracy in all product samples.Obviously, such a recurrence beneficial effect on the appearance of lecturing borders.

few words about the installation of granite curbs

Work on laying the stone has a typical sequence or different specific requirements.As in other cases, when fit any granite, is placed in the border previously prepared and marked corresponding groove depth.Must be respected the required height of the protruding portion, as already mentioned, an average of about 10 cm.

At the bottom of the groove is placed a layer of sand to 20 cm, depending on the anticipated loads.On top of the sand cushion sprinkled two layers of gravel medium and fine fractions.After the layers were thoroughly compacted, stacked dry mixture of cement and sand (1: 3) is 5 cm layer

curb block is established and carefully driven into the resulting cushion on the same level with the blocks defined earlier..After the installation is done copious sprinkling, to strengthen the pillows.This operation must be repeated for several days.
