How to Fix a Cracked Uneven Concrete Patio
Over time, the concrete that makes up your patio walkway may begin to settle or crack. It may also slope at an angle, creating a dangerous trip hazard as well as an unsightly look. Learn how to fix cracked, uneven concrete patio and restore the surface to its original condition.
What Causes Cracked Concrete?
A cracked uneven concrete patio can be due to a number of reasons. One main cause is due to the soil beneath. The Dallas Fort Worth area is known for clay-based soil, which is highly expansive. The soil expands and contracts as it absorbs moisture. In turn, this causes the concrete to settle in various sections and often unevenly. This leads to sloping and eventually cracks.
What’s the Solution?
While DIY solutions are available, they require extensive knowledge of concrete repair. You will also have to rent expensive commercial equipment. An uneven concrete patio is better left to a technician to diagnose and repair.
Several options are at your disposal. An inspector will make a recommendation based on the type and degree of damage. Usually, the methods come down to the ones listed below.
This method is also known as slabjacking. With this procedure, a small hole is drilled into the concrete. The hole serves as an entry point for pumping a mortar-based mixture into the soil beneath. The mixture hardens and fills in the gaps in the soil that caused the sloping and settling. Similar solutions include using a polyurethane mixture for filling in the gaps in the soil.
This is an inexpensive and non-invasive process of removing surface-level cracks in the concrete. Many homeowners find this solution to be a quick-fix. In many cases, however, resurfacing only masks the real underlying problem. While it may conceal the cracks, it does not address the settling soil beneath.
Replacing the Concrete
You can completely replace the cracked concrete. Since this is usually the most expensive solution, a technician may only recommend it if the concrete has settled or sloped to a degree that is irreparable by mudjacking or another method.
