Curbs are usually formed of natural stone, although concrete curb, usually combined concrete curb and gutter, are increasing very rapidly in recent years—partly because of the decrease in the price of Portland cement. Granite is the best natural stone, but it is usually very expensive. Limestone and sandstone are frequently used, but they are generally too easily chipped or broken. Concrete, unless made with unusual care or protected by steel on the edge, is too friable for a business street where heavy loads frequently back up against the curb.
They are 4 to 8 inches thick, usually 4 to 6 inches, depending upon the quality of the stone and the locality. The depth must be sufficient to prevent the thrust of the earth behind the curb from overturning it, and is usually 18 to 24 inches. If the section are to short, it is difficult to keep them in place and the general appearance is not good; and if they are too long, it is difficult to handle and set them, and nearly impossible to get a firm bearing on the bottom. They usually vary from 3 to 8 feet.
Curbs help to define your garden, patio and driveways; they can be matched with pavers for a uniform look. The main aim of landscaping to create a smooth transition from the outdoors to the indoors and curbs help them do the same. Curbstones are used for roads, driveways, parking lots and many other landscape construction applications.
