According to HomeAdvisor, a driveway repair professional will charge as little as $300 to fix minor concrete driveway cracks, but most homeowners can do the job on their own with a rubber or synthetic crack filler. This costs about $0.10 to $0.15 per linear foot—but watch out if cracks are larger than 1/8 of an inch.

Deep cracks or cracks over 1/4-inch wide usually signal more serious problems. While they can be filled, the fix is often temporary. Uneven cracks bigger than an inch wide occur more often in older driveways than in newer ones and almost always indicate underlying structural issues.
Crack sealing is a more costly procedure for the pavement owner but provides substantial value due to its long life expectancy. While crack filling may only last one or two seasons depending on the cracks activity, crack sealing can last up to 8 years or more and is considered a permanent treatment.

While you may see small driveway cracks as nothing important, they can be the first sign that you may have foundation issues.
Uneven drying, shrinkage and temperature changes can all cause fractures in your slab. To avoid water seepage and further damage, it's critical to seal any cracks that develop.
Over time and exposure to the elements exterior concrete can develop cracks due to temperature changes, ground movement, improperly placed joints and excessive loads. Once a crack develops it is important to seal the crack from water to prevent further deterioration.
Apply the filler using a caulking gun if available. If you don't have a caulking gun, the filler can be poured carefully into the crack. Use a putty knife or trowel to smooth out the surface of the crack. If a putty knife or trowel is non't available, you can use rubber gloves and smooth the crack out with your thumb.

Concrete driveways are a common part of the exterior of a home. They provide an even surface for vehicles and can be an integral part of providing access to a home. However, concrete will almost always crack and this is often times just part of the curing process.
Repairing Cracks in Your Driveway
Cracks up to 3/4 inch wide can be repaired with a pourable or tubed asphalt patch product. A tubed product requires a caulk gun for application. Some asphalt crack filler seals cracks up to 1 inch wide.
Pour enough dry concrete mix into a 5-gallon bucket to repair any cracks and patch damaged areas. Sand mix or concrete resurfacer, which do not contain gravel, may be used if the area to be repaired is not large or deep. A standard concrete mix that contains gravel works best for patching large or deep areas.
Structural concrete cracks have the potential to negatively impact the durability and strength of a concrete structure. These cracks are general recognized as serious if they are progressively widening, retaining dirt, allowing penetration of moisture, or developing in highly visible locations.
