Routed and Sealed Driveway Crack Repair in Oklahoma City

OKC Driveway Repair Co. does driveway crack repair across Oklahoma City using routed cracks, backer rod and flexible polyurethane sealant. Driveway crack repair costs about $3 to $8 per linear foot in the metro, and most drives need 20 to 60 feet, so a typical job lands around $250 to $500. Sealing is the cheapest repair there is, and on clay soil it is the one that keeps small cracks from turning into sunken panels.

What happens on the first visit

• Measure every crack for length and width; a feeler gauge or a coin tells us which ones are still hairline.
• Check both sides. If one side is higher than the other, it is not a sealing job, and we say so.
• Look at the joints. Rotted wood strips and empty saw cuts let in as much water as the cracks do.
• Price per linear foot, with the small-job minimum shown up front.

How we seal a driveway crack

Rout

Hairline cracks are too narrow for sealant to grip. We run a crack-chasing blade along each one to cut a clean, square reservoir about ½ inch wide. That gives the sealant two solid faces to bond to and enough body to stretch.

Clean and rod

Dust and debris are blown out and the edges are dried. Then we press closed-cell backer rod into the crack at the right depth. The rod stops the sealant from bonding to the bottom of the crack, so it bonds only to the sides and can stretch like a rubber band when the crack opens in winter.

Seal

We fill with self-leveling polyurethane on flat drives and gun-grade polyurethane on slopes, tooled flush inside the crack. We don’t smear sealant across the surface: smeared sealant peels within a season and leaves a dark stripe. Foot traffic is fine in a few hours and cars the same day.

Which cracks matter in Oklahoma City

Not every crack is a problem. Concrete shrinks as it cures, and fine cracks are normal. In Oklahoma City the cracks to worry about are the ones that let water in. The metro’s red clays, such as the Kirkland series, are rated high for shrink-swell, so water that gets under the slab softens the base in spring and leaves voids when it dries in summer. With 71 days a year at or below freezing (NWS normals), water in an open crack also freezes and thaws many times each winter and pries the edges apart.

The ones that need more than sealant:

• Wider than ¼ inch, or growing every season.
• Stepped, with one side higher than the other. That is settling; see driveway leveling.
• Spiderweb cracking in one area, a sign the base under that panel has failed. That panel needs replacement.

Paying for it

Crack sealing is priced per linear foot with a small-job minimum of about $250. The cost to fix cracks in a driveway guide breaks down DIY, sealing and panel replacement side by side. Insurance almost never covers cracking from shrinkage or settling, which is one more reason to keep this repair small and cheap.
