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.

Yes, permeable paving is expensive. For driveways, expect to pay up to $70 per square foot; for patios, permeable paving can cost up to $30 per square foot. Costs will depend on the type of material you choose, plus the standard labor rate in your area.

The most obvious disadvantage of permeable paving is that the cost is typically higher compared to non-permeable concrete, pavers, or asphalt methods. Also, the porous material can get clogged with dirt and debris, requiring cleaning and power washing more frequently than standard paving materials and methods. Although permeable paving is not ideal for highways, airports, and other surfaces supporting heavy traffic and machinery, it is suitable for regular residential driveways.
