Interlocking concrete pavements are a special dry mix pre-cast piece of concrete commonly used in exterior hardscaping pavement applications. Unit Pavements or block paving, nicknamed concrete pavements in the United States were developed before the Second World War by the Dutch and introduced into the United States in the early 1970s.
Interlocking paving stones are installed over a compacted stone sub-base and a leveling bed of sand. Concrete paving stones can be used for walkways, patios, pool decks and driveways and airport or loading docks.
Instead of connecting the pavers by pouring grout between the joints as one would with tiles, sand particles are spread over the pavers and tamped down. The sand stabilizes the interlocking pavers, yet allows for some flexibility. This type of pavement will absorb stress such as small earthquakes, freezes and thaws, and slight ground erosion by flexing. Therefore, they do not easily crack, break or buckle like poured asphalt or poured concrete.
Kargar offers these pavers on the front driveway, walkway and back lanai as a standard feature. Most communities require the brick pavers on the front walkway and driveway but Kargar offers these same pavers on the back lanai as well to increase home value along with the appearance of the home.
