Yes, you can put thin pavers over a concrete driveway. However, it's always best to talk to a driveway installer before starting. You'll need to ensure that the concrete below is in good enough shape to hold the pavers and that the driveway will still meet local building codes.

Maintaining a driveway depends on its material. For concrete and asphalt, it's best to clean the surface thoroughly twice a year with a stiff broom and a pressure washer to remove accumulated dirt and debris. Sealing the driveway is crucial to protect it from water damage and freeze-thaw cycles. Before applying a sealant, pressure wash the surface to remove any loose sealant, dirt, or stains, as sealing over them will trap them. Any cracks or expansion joints should be filled with a flexible polyurethane caulk or asphalt sealer. In colder climates, use sand instead of salt for de-icing. Sand helps melt snow and ice without accelerating the freeze-thaw process, which can cause cracks.

The most common causes of sunken pavers are poor base preparation and insufficient compaction. The problem could also be how your pavers were installed. If the soil beneath your patio or walkway wasn't compacted, it will pull pavers down as it settles. Additionally, using bare soil instead of making a paver bed with compacted gravel and sand can cause sinking over time. To fix sunken pavers, consider recompacting the base and addressing any drainage or erosion issues in the area.

Driveway paving costs around $4,500 on average, but depending on many factors, you could pay anywhere from $2,500 to $6,600 or more. The size of your driveway will usually be the most significant factor, with more square footage increasing your costs. You can expect to pay between $2 and $15 per square foot for paving services. Some other factors that play a role include the following:

• Quality of the materials

• Contractor’s experience and expertise

• Site preparation and grading, if necessary

• Layout of your driveway
