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.
Power wash brick paver areas using a 2700 psi power washer or greater. You may or may not need to use a paver cleaner during this process. Sweep joint sand into all the joints of the pavers and water down with a light spray from a garden hose. Sweep sand and water down a second time to ensure joints are full of joint sand. Once dry confirm joints are full with joint sand and move on to the next step. Having these joints completely filled and compacted will help maintain paver stability. Apply a joint stabilizing sealer on all the paver areas. The sealer hardens the sand which helps prevent water intrusion in the joints and insects digging through it! Follow the instructions of the manufacturer on how to apply sealer.
The sand bed should be up to 1 inch think. Joints are filled with sand and a perimeter restraint is generally necessary. If pavers are to be grouted a stable base of concrete with latex or acrylic admixture added is necessary. Expansion joints are necessary to allow for some movement. It is generally necessary to have perimeter restraints. While many people truly love the unique and versatile look they can achieve with the use of driveway pavers some people still do not realize why they need to invest in sealing driveway pavers. Paver sealing in Michigan can be even more important because of the ever changing weather conditions that the pavers have to be protected from. Brick sealing can increase the life of your driveway reduce weeds and protect the paving from fading and stains.
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.
