Crack Filling & Seal Coating in Casper, WY

Crack filling and seal coating are the cheapest ways to make asphalt last in Casper. Cracks let meltwater into the base, where it freezes and breaks up the pavement. Sun and wind dry out the surface until it turns gray and brittle. Filling cracks every fall and seal coating every few years address both.

Crack filling

Each crack is blown free of sand, dirt and weeds, wider ones are routed to a clean channel, and hot rubberized sealant is poured in. It grips both walls and stretches as the pavement moves through Casper's big temperature swings. September and October, ahead of the first hard freeze, are ideal. A web of linked cracks, the pattern called alligator cracking, points to a failing base and calls for a patch, not sealant.

Seal coating

Seal coat is a thin protective layer spread over clean, crack-filled asphalt. It blocks UV light, keeps water from soaking into the surface and resists oil and fuel drips. HomeGuide recommends sealing in dry weather between 50 and 95 degrees and waiting 3 to 6 months after new asphalt is laid. In Casper, that means summer.

Sun and wind

Casper gets more than 3,300 hours of sunshine a year, and wind carries grit across pavement. Both wear down the surface. A seal coat every few years slows that wear. HomeGuide lists an interval of 2 to 10 years depending on sealer and climate. Sealing every year can build up a layer that flakes.

What a fall maintenance visit covers

A typical fall visit includes blowing the pavement clean, filling every open crack, marking any failed areas for spring repair and noting edges that plows are likely to catch. For lots, we add a quick check of the striping and accessible stalls. That one visit is the most cost-effective thing most Casper property owners can do for their pavement.

Signs it is time to seal

• The black has bleached to a dull gray
• Small stones are loose or showing
• Water soaks in instead of running off
• Oil and fuel stains are spreading

Shops and lots

For shop aprons and yards, seal coat helps resist fuel and hydraulic fluid drips. Lots are sealed a section at a time so customers can still park, and the lines go back on once the coat has cured.
