Concrete Driveway Cracks: Causes, Maintenance and Repair Tips
Monday, April 13, 2020 4:02:00 AM Australia/Melbourne
A driveway isn’t just the entryway to your home or the introduction to your property – it is also an element that makes your home more attractive. It adds value, visual interest and function, influencing the first impressions of guests and people who pass by your house.
Concrete driveways, especially, are a popular choice among homeowners for their versatility and durability. However, just because they’re hard-wearing doesn’t mean they don’t require maintenance and repair. According to Fair Trading NSW, cracking in concrete is common and it's not always due to unsatisfactory workmanship.
Causes of Cracked Concrete Driveways
- Wear and tear
Over time, your concrete driveway will start developing surface-level damage such as hairline cracks. Hairline cracks are often caused by overexposure to water during the curing period.
Road chemicals can also weaken the surface of your concrete and produce hairline cracks. These hairline cracks stay harmless but they will reduce the visual appeal of your drive. When you don't fill in the gaps with the proper repair products for concrete cracks, weeds and shifting soil will search out the weak points and expand them.
- Bad gutters
If you have a missing downspout or clogged gutters, heavy sheets of water will hit your driveway during rainstorms and wear away your concrete. Depending on the problem areas, water will seep into the gaps and cracks as well as into the adjacent foundation.
- Tree roots
Tree roots don't directly harm concrete slabs. Instead, they push around the soil in an endless search for water. This can cause pressure cracks on your concrete or lift up your driveway slabs.
Other common causes of cracking include commercial or heavy vehicular traffic, sprinkler systems, shrinkage stress and soil movement due to changes in moisture content brought about by drainage problems or garden watering.
Concrete Driveway Maintenance and Restoration Tips
- Clean it regularly
Keep your concrete clean by sweeping or blowing away dirt, grass clippings and leaves at least once a week. If grass and weeds begin to take root, remove them immediately so they don't begin to grow through the fine gaps and eventually cause larger cracks.
- Remove stains
Concrete is a porous material so oil spills and leaks will stain its surface immediately. For stubborn grease spills, use kitty litter to absorb the stain and then dish soap and water to clean the area afterwards. If accessible, a pressure washer will remove the stains faster and better.
- Apply sealer
In order to reduce the probability of cracks and other types of driveway damage, apply a sealer to hold the concrete's colour and slow down ageing and weathering.
- Repair it with concrete caulking
You can easily repair small spider cracks and chips with concrete patch repair products that will restore the strength and aesthetic value of your driveway. Filling in the gaps will prevent dirt and debris from settling and increasing the damage to your driveway.
