Project overview

A homeowner just outside Port Byron, Illinois had an asphalt driveway ready for routine protection. The crew cleaned and prepared the existing surface and applied a new coat of professional-grade sealer, restoring the driveway’s dark, even finish.

Project details

Preparation came first: the existing asphalt was thoroughly cleaned so the sealer could bond to the pavement rather than to dirt and loose material. A fresh coat of professional-grade sealer was then applied across the full driveway.

Sealcoating is a protective layer, not a structural repair. It shields asphalt from oxidation by sunlight, slows moisture penetration, and resists everyday wear, while bringing back the rich black appearance of newer pavement.

What homeowners should know

Asphalt is a flexible pavement bound together by a petroleum binder, and that binder is what sunlight and water attack. As it oxidizes, the surface turns grey and brittle, fine aggregate loosens, and small cracks open up. Sealer replaces the lost surface protection so the binder underneath stays flexible longer.

The practical maintenance rhythm most driveways need: sealcoat roughly every two to three years, fill cracks promptly before water gets in and freezes, keep water draining off the surface rather than ponding, keep leaves and petroleum spills cleaned off, and avoid heavy vehicles or sharp turning on hot days. Done consistently, this is what keeps a driveway from reaching the point where only a full replacement will do.

Sealcoating is the same service Behncke performs on commercial parking lots; the residential version follows the same cleaning-first approach on a smaller scale. See the driveway sealcoating page for how the process works and when it makes sense.
