Best driveway sealcoating pros near Presho, SD

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.

Though they may look similar, tar and bitumen come from different sources. Bitumen is a petroleum product—extracted during crude oil refining—and is mostly made up of hydrocarbons. Tar comes from burning down organic materials like coal or wood. Bitumen is strictly oil-based, while tar is a mix of compounds from natural sources. Both are used as binders in paving; however, bitumen is the standard for today’s asphalt. Tar use has mostly faded out of road construction.

Sealing coat asphalt after 6-12 months and then every 2-3 years is recommended.

To extend the lifespan of an asphalt surface, sealcoat it every 2-3 years, repair cracks promptly, and clean it regularly to remove debris.
