Concrete leveling, also known as slabjacking or mudjacking, is a process used to level out uneven concrete surfaces such as sidewalks, driveways, and patios.
However, not every settled concrete area is qualified to be raised through this process. For instance, badly cracked concrete does not have good long-term stability and may need replacement. There are also restrictions that may prevent your concrete from being raised such as steps or gazebos that are constructed on top of your concrete. Also previous repairs or replacement to your concrete which may prevent your slabs from being returned to their original height and condition.
The estimating process has evolved using digital technology. Often, photos will provide a qualified and experienced contractor will the initial information he needs to determine if your concrete can be raised. While the best option is always to get an assessment from a tradesman, not a salesman, some companies will send a sale agent out to your home. While this may sound convenient, it may result in an assessment by an unqualified individual who lacks years of experience and background in concrete repair necessary to provide a proper assessment. It may also result in a higher cost and a sense of urgency to sign and accept terms on the spot with discount offers if you” sign today.” It is always best to give proper time and consideration to any repair and cost and who will be onsite completing your repair. Here is how a concrete leveling appointment might work:
- Initial Inspection: If an assessment cannot be provided through photos, a concrete leveling contractor, or as mentioned above, a salesperson, will come to your property to inspect the concrete surface that needs to be leveled. They will assess the extent of the damage and determine the best course of action to level the concrete.
- Preparation: The contractor will prepare the area around the concrete surface by cleaning it thoroughly and removing any debris or loose material.
- Drilling: Small 5/8” to 1” holes are drilled into the concrete surface at strategic locations, usually about 6-8 feet apart.
- Injection: A mixture of cement, sand, and water, or a poly foam, is injected through the drilled holes to lift the concrete slab to its desired level.
- Finishing: Once the concrete is level, the holes are filled with cement and smoothed out to match the surrounding surface.
- Clean up: The contractor will clean up the work area, removing any excess material and debris.
The entire process typically takes a few hours to complete, depending on the size and complexity of the job. Once finished, you can use the leveled surface as normal.
