The side stone (border) is mainly used to separate the pedestrian part of the street and the carriageway. It is indispensable when laying paving slabs or pavers. It is mainly made of concrete. Such a stone is relatively cheap. When laying it should be well fixed. In general, the side stone should have qualities such as durability and resistance to weather changes.
Concrete curb
The most important positive quality of a concrete border is its cheapness. However, a large temperature difference is fatal for him. Water entry is also bad. The concrete side stone that has absorbed water can easily collapse if there is frost after rain. Water that has turned into ice will simply rip it from the inside. Cracks and chips will appear. Therefore, in our country, curbs made of concrete are so often changed. In addition, in its manufacture they often deviate from technology in order to speed up the production process. A special operation of long cooling of the concrete mixture is skipped . Instead, it is steamed. The result is deplorable. After 4-5 years, it has to be completely replaced. When constructing cottages, you sometimes have to use a curved-shaped side stone. It is also made of cast concrete with the use of reinforcement. It will, of course, be quite expensive, but the path and sidewalk will turn out to be very beautiful. The best concrete bead stone is made of cement-sand concrete with the addition of crushed stone or gravel. Concrete borders can be made not only of gray (familiar to us) color. It can be done in any color and even imitate marble, granite or malachite. In this case, the stone is painted not only superficially, but throughout the entire depth. This color is maintained for the entire service life of the border.
Natural side stone
The side stone made of natural material is more aesthetic and reliable, as well as more environmentally friendly than its counterpart made of concrete. It is much stronger, has better frost resistance, wear resistance and better hygroscopicity. Usually a full-sawn border is produced (all 6 of its sides are sawn). Such stones are produced with a decorative profile and relief, even with a polished surface. A border with a polished surface is used to give solemnity to any part of the street. It will emphasize the style of the building and the surrounding landscape.
The most reliable material for its manufacture is granite. It gives unlimited possibilities for processing, aesthetic and durable. Granite side stone can be used to separate the carriageway, pavement, lawn and other elements of the urban structure. It can also be used to frame stacked pavers or paving slabs. Granite side stone sizes are fixed, established by special GOST, usually this section is 300x150mm. This is a regular road border. For walkways, granite bead stone with a cross section of 200x80mm is used.
