Three Options To Level Uneven Concrete

Uneven or broken concrete can make your patio, drive, or sidewalk look unattractive, as well as pose a safety hazard. Yet, it can be tempting to put off repairs since many people think the concrete will have to be removed and replaced. Fortunately, there are several options to fix uneven concrete slabs without full teardown and replacement. The following guide will go over your options.

Option #1: Cut out the damaged section

This method does require some removal and replacement, but only of the damaged section. This often works well for sidewalks where it may be only a few relatively narrow feet that are a problem. A concrete contractor will use a concrete saw to remove the damaged section. They will then rebuild the base and pour fresh concrete that is level with the abutting sections. The only major issue is that sometimes the color of concrete doesn't match exactly.

Option #2: Resurfacing and patching

If cost is a concern and you only have a small area to repair, this may be an option. The lifted portion is ground down so that it is level with the neighboring section of concrete. Then, a patch is applied over the top to join the sections back together at the same level.

In other cases, the surface may simply be roughened slightly, and then a concrete patch is applied to create a ramp between the two different layers thus resulting in a gentle slope as opposed to stepped rise. These are not the most attractive options, since the patch is usually quite obvious. It is best to save this repair for locations where it won't be highly visible.

Option #3: Mud jacking

Concrete mudjacking, or slab jacking, works very well when one section of concrete is lower than another, particularly if the concrete hasn't yet cracked and instead has just developed a slope. It is often used on large slabs, such as patios or even foundations, where a portion settled more than another. A contractor pumps a concrete mixture, called mud, beneath the sunken portion of the slab, taking great care to control the speed, location, and amount of the flow. This gradually lifts the slab until level. The result is a level slab with no underlying gap, which means it shouldn't lower again and there should not be any cracking.
