Best paving pros near Aberdeen, WA

If your new pavers look dull or unclean, it is likely due to efflorescence, a chalky, white powder that forms when lime in the pavers gets wet. This condition often resolves on its own, as rain will naturally wash it away within about a year. For faster results, you can use a pressure washer to clean the pavers. Alternatively, consider using cleaning products specifically designed to remove efflorescence or applying sulfuric acid crystals.

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.

While blacktop is a type of asphalt, the terms should not be used interchangeably, as not all asphalt qualifies as blacktop. The primary differences are in their composition, production process, and ideal applications. Blacktop contains more stone than other types of asphalt and is heated to a higher temperature during production—300°F or more—while hot-mix asphalt is heated to between 275°F and 300°F. The ratio of bitumen (a tar-like crude oil) is a key differentiator, though sources vary: some state blacktop has less bitumen, making it less durable, while others claim it has a higher ratio. Due to these differences, asphalt is generally more durable and better for high-traffic areas like highways and streets, while blacktop is more suitable for playgrounds and residential driveways. For a driveway project, it is best to consult a professional to determine the most appropriate material.

After removing existing moss, consider using paver blocking sand to fill the joints. This specialty material hardens once placed and serves as an effective barrier against moss and weeds. From there on, regularly clean your pavers and try to keep them dry. You can also seal your paver as a semi-permanent solution — just make sure you reseal every 3 to 5 years.
