Concrete is an essential building material in modern construction, used in various structures such as roads, bridges, and buildings. Its durability and strength make it a popular choice for homeowners too, especially for driveways, walkways, and patios. However, over time concrete can crack or sink due to various reasons like soil settling or poor installation.
In such situations, concrete lifting becomes necessary to restore the functionality and aesthetic appeal of your home’s exterior surfaces. Concrete lifting is a technique that involves raising sunken concrete back to its original position using specialized equipment and materials.
This guide will provide you with everything you need to know about concrete lifting for your home, from its benefits to the process and costs.
What is Concrete Lifting?
Concrete lifting, also known as slab jacking or concrete leveling, is a process that involves raising sunken concrete back to its original position.
According to the professionals from PolyLevel, two primary methods of lifting concrete slabs are mud jacking, which injects a slurry mixture beneath the slab, and polyurethane foam injection, which uses an expanding chemical foam to lift the slab. This technique is used when concrete has settled or sunk due to soil erosion, poor compaction during installation, or other factors.
By using specialized equipment and materials, the sunken portion of the concrete can be lifted and leveled, restoring its functionality and appearance. Concrete lifting is a cost-effective solution compared to completely replacing the damaged surface, making it a popular choice among homeowners.
Causes of Sunken Concrete
There are various reasons why concrete can sink or settle over time. One of the primary causes is soil erosion, which occurs when water seeps into the ground and washes away the soil beneath the concrete, creating voids. These voids can cause the slab to sink or crack under its weight, leading to an uneven surface.
Poor compaction during installation is another common cause of sunken concrete. If the soil is not compacted properly before pouring concrete, it can lead to settlement over time. Other factors such as tree root growth, heavy loads on top of the slab, and plumbing leaks can also contribute to the sinking or cracking of concrete surfaces.
Benefits of Concrete Lifting for Your Home
Concrete lifting offers several benefits for your home, making it a preferred choice among homeowners. One of the main advantages is its cost-effectiveness. Instead of completely replacing the damaged surface, concrete lifting allows you to restore and level the existing concrete, saving you time and money.
It also minimizes disruption to your property, as the process requires less equipment and manpower compared to traditional replacement methods. Concrete lifting also provides a long-term solution, as the lifted slab will be more stable and durable than before.
Also, by restoring the functionality and appearance of your exterior surfaces, concrete lifting can enhance curb appeal and increase property value.
The Process of Concrete Lifting
The process of concrete lifting involves several steps that require specialized equipment and materials. The first step is to drill small holes into the sunken concrete surface, usually about 1-5 inches in diameter. Next, a grout or foam mixture is injected through the holes using high-pressure equipment, filling any voids beneath the slab and raising it back to its original position.
Once the desired height has been achieved, the holes are filled with cement or another filler material, and the surface is smoothed out. This entire process typically takes a few hours to complete for an average-sized project, and you can use the lifted surface immediately after completion.
Cost Considerations for Concrete Lifting
When considering concrete lifting for your home, cost is a crucial factor to consider. The overall cost of the project will depend on various factors such as the size and condition of the area to be lifted, accessibility, and materials used.
On average, concrete lifting can range from $500 to $1500 per project, making it a more affordable option compared to complete replacement. Note that delaying repairs or opting for temporary fixes can result in larger expenses in the long run.
Maintaining the Results of Concrete Lifting for Your Home
Maintaining the results of concrete lifting is essential to ensure the longevity and effectiveness of the repair. After completion, regularly inspect the lifted area for any signs of cracking or sinking and address them immediately. Proper drainage around your home can also help prevent future soil erosion, minimizing the chances of sunken concrete. Avoid placing heavy objects on top of the lifted surface, as this can cause further damage.
Concrete lifting is an effective solution for sunken or cracked concrete surfaces around your home. It offers several benefits, such as cost-effectiveness, minimal disruption, and long-term results.
By understanding the process and costs involved, you can make an informed decision about whether concrete lifting is the right option for your home.
