When installed properly over a well-compacted subbase (see Installing Concrete Pavers), precast concrete pavers will rarely crack, shift or settle under normal foot or vehicle traffic. The compacted bed of aggregate beneath the pavers will help prevent settlement, and the joints, or gaps, between the pavers will allow for expansion so the pavers will not crack due to freezing and thawing.

Pavers can settle in spots over time if they aren’t installed properly over a stable subbase. However, they can easily be reset by removing the affected pavers and regrading and recompacting the subbase. Pavers can also be removed and reinstalled in this manner if utility repairs are required.

Typically, routine maintenance of paver surfaces involves removing dirt and leaves by sweeping and occasional rinsing. For heavy oil or grease stains, use a pressure washer with an appropriate cleaning solution. Depending on weather exposure, you may need to replenish the sand in the paver joints every 2 or 3 years if it washes away due to erosion. If polymer sand is used at the time of paver installation, joint sand addition may not necessary. This special type of sand contains a polymeric additive that binds and hardens the sand and helps to prevent erosion. Sealing concrete paver surfaces will also help to lock in the sand while protecting the pavers from staining. However, sealing does require periodic reapplication depending on the product used and traffic exposure.

In the winter, paver driveways can be plowed or shoveled without dislodgement because they typically have chamfered edges and joints. However, don’t use sharp objects to chop ice, which can damage the pavers. Instead, add traction with sand or apply a noncorrosive deicer, such as calcium magnesium acetate.
