1. Shrinkage Cracks
Shrinkage cracks are thin cracks that occur due to the natural drying and curing process of concrete. They are naturally caused by the contraction of the concrete as it cures and dries.
Shrinkage cracks are also known as hairline cracks and can be found criss-crossing on the surface of your concrete driveway.
In the construction stage, shrinkage cracks can be minimized (though never eliminated) by regulating the rate of water evaporation as the concrete cures.
Shrinkage cracks are superficial and do not affect the structural integrity of the concrete slab. Most homeowners accept their presence and simply ignore them.
However, if the shrinkage cracks widen, it is best to fix them by using a concrete patching compound or filler. Start by cleaning the cracks and removing any loose dust or concrete powder in them.
Then, apply the filler into the cracks. Use a trowel, putty knife or a spatula to smooth out the fill and make it level with the surrounding concrete. Allow it to dry.
2. Settlement Cracks
Settlement cracks are caused by the shifting or sinking of the ground beneath the concrete driveway. They are characterized by wider cracks that may be uneven or offset.
If you notice these types of cracks on your driveway, it’s important to address them promptly.
To repair settlement cracks, you will need to stabilize the underlying ground and fill the cracks. This process typically involves injecting a polyurethane foam into the voids beneath the concrete to lift and level it.
Once the driveway is stabilized, you can use a concrete patching compound to fill the cracks and restore its appearance.
3. Frost Heaving
Frost heaving occurs when moisture in the ground freezes and expands, causing the concrete to rise and crack under the stress.
The problem of frost heaving is, of course, more common in colder climates. Signs of frost heaving include uneven or raised sections of the driveway.
Frost heaving cracks can look quite similar to settlement cracks. To fix frost heaving, you will need to remove the affected areas of the driveway and re-pour concrete.
It’s essential to address the underlying drainage issues to prevent future frost heaving. Ensuring proper slope and installing adequate drainage systems will prevent repetition of the problem in future.
4. Structural Cracks
Structural cracks are serious issues as they can compromise the integrity of your concrete driveway. These cracks are wider and deeper than other types and may be accompanied by sinking or heaving of the concrete.
If you notice structural cracks, it’s crucial to seek professional help immediately.
Repairing structural cracks requires expert assessment and intervention. A qualified contractor will evaluate the extent of the damage and recommend the appropriate repair method.
This may involve reinforcing the concrete with steel bars, injecting epoxy resins, or even replacing sections of the driveway.
5. Spalling & Scaling
Spalling and scaling refer to the chipping, flaking, or peeling of the concrete surface. These problems are usually caused by freeze-thaw cycles, poor curing, or the use of low-quality concrete.
Spalling and scaling can give your driveway an unsightly appearance and expose it to further damage.
To fix spalling and scaling, start by removing the damaged concrete with a hammer and chisel. Clean the area thoroughly and apply a concrete resurfacer to restore the surface.
This will create a smooth and uniform finish, protecting the underlying concrete from further deterioration.
6. Stains & Discoloration
Stains and discoloration can occur on concrete driveways due to oil spills, rust, mold, or other substances. These common concrete driveway stains detract from the overall clean looks of your driveway.
To remove stains, start by applying a degreaser or a mixture of baking soda and water to the affected areas. Scrub the stains with a stiff brush and rinse with water.
For stubborn stains, you may need to use a pressure washer or specialized concrete cleaners. Regularly sealing your driveway will help prevent future stains.
7. Pitting & Deterioration
Pitting and deterioration manifest as small holes or craters on the surface of the concrete. They can be caused by the use of de-icing salts, exposure to harsh chemicals, or the natural aging of the concrete.
To repair widespread pitting and deterioration, you can use a concrete resurfacer such as a rubber coating.

Sweep the concrete driveway to remove dirt & debris. Use a pressure washer and a cleaning solution to remove caked mud and grime. Apply a coat of primer followed by 2 coats of rubber coating and let it dry.
In case the pitting is localized, you can clean up the area, apply a patching compound and then cover it with a couple of coats of high quality topical sealer.
8. Standing Water
Standing water on your driveway can lead to a host of problems, including erosion, cracking, and damage to the concrete. It’s important to address this issue as soon as possible to prevent further deterioration.
To eliminate standing water, ensure that your driveway has proper slope and drainage. Consider installing a channel drain or a French drain system to redirect the water away from the driveway.
If necessary, consult a professional to assess and implement the most effective drainage solution for your specific situation.
9. Erosion & Washouts
Erosion and washouts occur when water flows over the driveway and washes away the underlying soil, causing voids beneath the concrete. This can weaken the driveway and lead to cracking or sinking.
To repair erosion and washouts, start by filling the voids with compacted soil or a flowable fill material. Once the voids are filled, you can restore the surface by applying a concrete patching compound.
Ultimately the long term solution is to install a proper driveway drainage system so as to prevent future erosion and washouts.
Bottom Line
Understanding and addressing common concrete driveway problems is essential for maintaining a functional and visually appealing driveway.
Whether you’re dealing with shrinkage cracks, settlement issues, or stains and discoloration, timely repairs and preventive measures can help extend the lifespan of your concrete driveway.
If you’re unsure about the severity of the problem or need assistance with repairs, don’t hesitate to consult a professional concrete contractor.
