Especially in Michigan, where weather conditions can put stress on outdoor surfaces, cracks in concrete driveways are very common. While certainly unsightly, some cracks are normal and aren’t cause for alarm. However, others can signal deeper issues that require attention from a Metro Detroit concrete contractor.
While concrete is a durable material that can last for many years, it can crack over time as it naturally expands and contracts with temperature changes. It can be difficult knowing which cracks are harmless and which ones need to be repaired. Your trusted contractor can evaluate your driveway and determine which cracks are typical and which ones may indicate structural problems.
Why Concrete Driveways Crack
Because concrete driveways are exposed to constant environmental and structural pressures, cracks can be a common occurrence. They can arise from:
- Freeze-thaw cycles
- Soil movement
- Heavy vehicles or loads
- Improper installation or base preparation
- Concrete shrinkage during curing
Now let’s take a look at the different types of cracks and what they mean.
Hairline Cracks: Usually Not a Major Concern
Small hairline cracks are the most common type of driveway cracking. These thin lines often appear as the concrete cures or as it naturally settles over time. They’re generally normal and don’t detract from the strength of the driveway. They are usually caused by shrinkage during the curing process or as a result of minor temperature changes.
However, keep an eye on minor cracks to ensure they don’t progress. Seal them regularly so water can’t get in and cause more damage.
Wider Cracks That May Need Attention
As cracks widen, they can start to pose underlying problems. Cracks that are larger than about ¼ inch wide invite water to slip under the surface of the driveway. Once that water hits the base layer, it weakens the soil or gravel foundation that supports the concrete. Cracking, shifting slabs, or uneven surfaces can result with the passage of time. If you notice cracks spreading across your driveway, it’s time for professional attention.
Uneven or Raised Cracks
If one side of a crack is higher than the other, this often means there is movement beneath the concrete slab. Not only can this situation create a tripping hazard, it may mean the driveway is no longer stable. This happens due to:
- Soil settling or erosion under the driveway
- Tree root growth pushing upward
- Freeze-thaw expansion beneath the slab
Multiple or Spreading Cracks
If you notice multiple cracks appearing in different directions, structural stress could be going on. This could be due to one of two things: deteriorating concrete or a shifting foundation beneath the slab.
Concrete repairs or resurfacing will be necessary to restore the driveway’s strength and appearance.
5 Signs Your Driveway Needs Professional Evaluation
Schedule an inspection with your Michigan concrete contractor if any of the following are present:
- Cracks wider than ¼ inch
- Uneven or raised sections of concrete
- Multiple cracks forming a pattern or network
- Pieces of concrete breaking away from the surface
- Water pooling near or inside cracks
Failure to address these situations could make them worse and result in higher repair or resurfacing costs.
Of course,not all cracks require immediate repair, but it’s important for Michigan homeowners to monitor all cracks to prevent larger problems later. Regular inspections, particularly after winter, can be very helpful in identifying and correcting concerning issues.
