MARBLE (GRANIT) SIDEWALK AND ROAD CURB (BORDER)

In modern Time, thedominant material for concrete curbs remain. The main advantage of concrete curbs - its relative cheapness. However, the use of granite curbs costsignificantly more than justifiable. To see this, it suffices to compare the strength, frostresistance, abrasion, water absorption. For all of these indicators is considerably inferior to theconcrete curb granite. As you know, the mostdeadly for these products is a significant temperature drop, along withexposure to moisture. It is worth mentioninghygroscopic, that is, to this indicator largely explains the fragility of theconcrete curbs.Hygroscopic material is the ability to absorb water. At the curb, made of concrete, even with theuse of special additives, which give the frost-resistant properties, the rateis 3-4%. While the granite intheir properties are not able to absorb more water than 0,2-0,45%. In the cold season, the water turns into icebegins to break the board inside the stone. Cracks, chips, rock becomes brittle, the process of destructionis accelerating.Initial cost savings of turns for the purchase of new borderstones, dismantling damaged and installing new ones. Unfortunately, often the producers of concretecurbs in order to accelerate the production of retreating from technology. It is expressed in the fact that instead of along cooling of concrete mix, it steamed in a special way. This can improve performance, but at the sametime from the curb of the concrete is less frost. As a result, the first signs of the destruction of the borderappear in the first year of operation, and its complete fracture occurs after4-5 years. In the case ofinstallation of granite curbs, the principle of "set and forget." Granite curbs, even after 20-30 years, however,does not show any visible damage. If you are looking for a quality curb, granite stone - the bestsolution!

Thus, despite the fact that the granite curb concrete is more expensiveinitially, its use will give significant savings in the future.
