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.

Compared to a 10x20 concrete driveway costing between $800 and $3,000, a resin bound driveway of the same size costing $3,900 to $4,000 is the more expensive option. However, the cost still makes resin a cheaper option compared to a 10x20 paver driveway costing an average of $12,000.

While water-related pressure caused by poor drainage is one common cause of paver cracking, other factors can include ground movement beneath pavers, heavy loads and wear and tear over the pavers, and climates with constant freeze-thaw cycles. In general, pavers should be resealed every three to five years to prevent cracking.

To adhere pavers to concrete, you can use either mortar or a concrete-specific adhesive. For border pavers, a polyurethane-based adhesive is a good choice as it expands and contracts with temperature changes, keeping them firmly in place. For the non-border pavers, polymeric sand is used between the joints to prevent shifting. In most cases, it is also recommended to lay a permeable sand layer below the pavers to ensure proper stability and drainage. Before starting, always take the proper preparatory steps for a professional result.
