Unlike asphalt pavers are virtually maintenance-free and do not need to be regularly sealed or replaced. By definition concrete pavers have a minimum compressive strength of 8000 psi (about 3 times stronger than regular poured concrete) and a maximum water absorption rate of 5%. Concrete pavers are extremely dense units which possess exceptional strength and durability superior stability under severe loads and are unaffected by the extremes of heat and frost. Each unit has joints that allow for a small amount of movement without cracking. Factory made pavers last for decades.
Natural Stone pavers are quarried stone which are cut to the right size. Generally these pavers are laid end to end which does require more labor time. There is little maintenance needed and the stone pavers will last a lifetime. On a per square foot basis most stone pavers will cost $10.00. If you choose unusual or rare stones the cost could be up to $30 per square foot. Concrete pavers are colored at the manufacturer and may fade over time. To prevent this the pavers can be cleaned and sealed. Concrete pavers are priced at $5 to $10 per square foot and are installed for an additional $5 to $10 per square foot. Sand-set is an economical installation method. Soil and gravel layer compaction is necessary for stability.
Compared to regular concrete pavers are crack free. Their inherent design allows them to flex and move because of their many dry joints between the individual pavers. No poured concrete is used in the installation only a compacted aggregate base and sand. Edge restraints can be packed concrete along the outer perimeter or special plastic edge restraints designed specifically for pavers. Tile stone flagstone or any other material that must be installed over a concrete slab is subject to cracking of the underlying slab. Poured concrete without stone on top will also crack because its the nature of concrete to crack. Expansion joints are intentionally placed in poured concrete applications to allow for this natural cracking. Unfortunately concrete does not always crack along the expansion joints. And when it doesnt the whole appearance can be ruined.
Dirt does not tend to tick on them stubbornly and hence a simple wiping of the surface or pressure washing if stains are too greasy gets rid of any unwanted deposited. In fact the water board recommends sealing concrete pavers in order to save water. By sealing a paver you are essentially putting a shield that protects it from being damaged due to various factors such as reaction with acid and fungal infestations. Further it prevents sand and cement in the joints from washing out due to heavy rains and storms thus preventing loosening of stones. The hazardous effects of freezing and thawing that tend to ruin most of the pavers is eliminated due to sealing. Sealing pavers protects them under all weathers and high traffic loads. As a result your paver is well preserved.
