Conclusion
A cracked and uneven concrete patio results from various causes. However, you should evaluate and assess the situation to determine the best approach to use when you notice the problem.
1. Fill and seal common concrete cracking with a caulk-based crack repair product
More than likely, your concrete patio has a few cracks in its surface. This happens for many reasons, including ground shifting, improper pouring conditions, and just the nature of concrete. But that does not mean you have to live with them just because these cracks are typical.
2. Straighten out crumbling corners with a concrete cleaner and patching compound
One of the most common patio issues facing homeowners is a chipped or crumbling corner. These corners deteriorate from age, water, and typical foot traffic. They start life as a sharp, attractive angle and wind up rounded over and crumbly. Luckily, there’s an easy solution to fix this on your own.
3. Dress up an older, unattractive space by covering your patio with pavers
Like anything else, patios become worn and dated. You can upgrade the look all together by covering your patio with pavers. While you might assume this is a pricey project that requires professionals, you can actually do this on your own!
4. Create a smooth, fresh surface atop your patio by resurfacing the slab
While they don’t rot, horizontal concrete surfaces are prone to pitting, spalling, and cracking. While covering the surface with pavers is always an option, a less expensive and easier route is to resurface the slab.
5. Repair and seal expansion joints to keep them working as designed
Not all cracks and gaps in concrete surfaces are bad. Expansion joints—the gaps created during installation between two concrete surfaces—are designed to allow the slabs to move, or give them somewhere to crack other than the field of the patio.
