Patching & Crack Repair in Ames, IA

Patching and crack repair matter more in central Iowa than in milder climates because of what water does once it gets into asphalt. Rain and snowmelt run into an open crack, soak the base, and freeze. Ice expands and pushes the crack wider. In spring the base thaws wet and soft, traffic presses the asphalt down, and the edges break into a pothole. Ames gets dozens of those freeze-thaw swings between November and April, so a crack left open in fall is often a hole by spring.

Crack filling

Cracks get cleaned out with air and filled with hot-poured rubberized crack sealant that stays flexible in cold weather. HomeGuide lists crack filling at about $0.50 to $3 per linear foot. The best time is late summer or early fall, when cracks have opened partway and the material can bond before winter.

Pothole and area patching

• Cold patch: a temporary fix for winter emergencies
• Hot patch: hot asphalt placed and compacted into a cleaned hole
• Saw-cut patch: the damaged area cut square, base repaired, and new asphalt placed full depth
• Infrared patch: the surrounding asphalt heated and blended with new material for a seamless repair

For holes that keep coming back, the saw-cut method is the one that lasts, because it fixes the base under the hole rather than just filling it.

Frost heaves and settled spots

A heaved or sunken section usually means water is collecting in the base. Patching over it without changing the drainage only buys a season. We dig out the area, replace wet material with crushed stone, and where possible give the water somewhere to go.

Edge repair

Asphalt edges break when they are unsupported, especially where cars cut across the lawn. We cut back broken edges, rebuild the base and backfill with soil so the new edge is supported.

Permits

Under the City of Ames driveway application, routine maintenance and partial repairs are exempt from the driveway permit. Patching and crack filling on your own driveway fall into that category.

Repair priorities on a tight budget

If you cannot do everything at once, fix things in this order: first, anything that lets water into the base, which means open cracks and holes near the low end of the driveway; second, broken edges where cars drive; third, cosmetic patches and sealing. Water damage compounds every winter, so stopping it is the best use of a small budget. We price each area separately so you can pick.
