Concrete raising is a process that involves lifting a sunken or settled concrete slab back to its original position.
It is often referred to as mudjacking or slabjacking. Understanding the causes and fixes of concrete raising must be considered.
Understanding the causes will help you prevent the issue from occurring in the future.
Meanwhile, understanding the fixes will help you address the problem efficiently and effectively, saving you time and money in the long run. It is crucial to understand the factors contributing to concrete settling or sinking, such as soil erosion, poor compaction, and water damage.
By doing so, you can take proactive measures to prevent the issue from happening again.
What causes the need for concrete raising
Concrete raising, also known as concrete lifting or mud jacking, is a process that involves lifting sunken or settled concrete slabs back to their original position.
Concrete can sink or settle for various reasons, and understanding these causes is crucial to prevent the issue from happening again. In this article, we will discuss the common causes of concrete sinking and offer tips to prevent it from happening.
1. Soil erosion: Soil erosion is one of the most common causes of concrete sinking. When the soil beneath the concrete slab washes away, it creates voids that can cause the slab to sink. This can happen due to poor drainage, heavy rain, or natural wear and tear. To prevent soil erosion, ensure proper drainage around the concrete slab. If you notice any signs of erosion, such as cracks or gaps around the slab, repair them immediately.
2. Soil compaction: Soil compaction occurs when the soil beneath the concrete becomes denser and settles, causing the concrete slab to sink. This can happen due to heavy foot traffic or vehicular traffic or when the soil is not compacted correctly during construction. To prevent soil compaction, avoid heavy traffic on the concrete slab and ensure proper soil compaction during construction.
3. Freeze-thaw cycles: In areas with cold climates, freeze-thaw cycles can cause the soil to expand and contract, leading to cracks in the concrete. Over time, these cracks can cause the concrete slab to sink. To prevent this, ensure proper drainage around the concrete slab and repair any cracks immediately.
4. Tree roots: Tree roots can grow and spread underneath the concrete slab, causing it to lift and crack. This is a common problem in areas with large trees planted near concrete structures. To prevent this, avoid planting trees too close to concrete structures or install root barriers to prevent the roots from spreading.
5. Plumbing leaks: A leak in the plumbing system beneath the concrete slab can cause the soil to become saturated and unstable. This can lead to soil erosion and eventually cause the concrete to sink. To prevent this, inspect your plumbing system regularly and repair any leaks immediately.
By understanding the causes of concrete sinking, you can take steps to prevent it from happening in the future. Regular maintenance, proper drainage, and avoiding planting trees too close to concrete structures can help keep your concrete slab level stable for years.
- Concrete raising lifts sunken or settled concrete slabs back to their original position.
- Common causes of concrete sinking include soil erosion, soil compaction, freeze-thaw cycles, tree roots, and plumbing leaks.
- To prevent concrete sinking, ensure proper drainage around the slab, avoid heavy traffic, regularly inspect the plumbing system, and avoid planting trees too close to concrete structures.
Signs of concrete raising
Concrete raising is a highly effective and reliable process to restore sunken or uneven concrete slabs to their original position. It is a crucial process that aims to address issues such as unevenness, cracks, sunken areas, and trip hazards that pose significant safety concerns for anyone using the area.
When concrete slabs become uneven, they create a potential for accidents and injuries. They can cause serious trip hazards, leading to severe falls.
Additionally, cracks in the concrete can weaken the structure, leading to further damage and the risk of collapse.
Sunken areas can indicate underlying problems like soil erosion and inadequate drainage, which can be detrimental to the longevity of concrete and the overall stability of the area.
It is essential to take prompt action to address these issues to avoid further damage and ensure the safety of everyone involved.
Trip hazards, in particular, require immediate attention as they can lead to severe accidents and injuries. Ignoring these problems can lead to costly repairs and even legal issues.
Concrete raising involves drilling holes in hollow or uneven concrete slabs and injecting cement and other materials beneath the surface. This mixture fills the voids beneath the concrete and raises it to its original level.
This process is environmentally friendly, cost-effective, and takes less time than traditional concrete repair methods.
Suppose you notice signs of sunken or uneven concrete slabs, such as cracks, trip hazards, or unevenness. In that case, contacting a professional concrete-raising company is crucial to restore the area to its original condition.
With their expertise and specialized equipment, they can quickly and efficiently restore your concrete slabs, ensuring they are safe and functional for everyone who uses the area.
Methods for Concrete Raising
Suppose you’ve noticed that your concrete surfaces, such as driveways, sidewalks, or other flat areas, have become uneven or sunken over time. In that case, there are several solutions that may be available to you.
Mud jacking is one of the most commonly used methods for repairing sunken concrete. This process involves drilling small holes into the concrete and pumping a mixture of soil, water, and cement underneath the slab to raise it to a level position.
Mudjacking is especially useful for repairing flat areas that have sunk over time.
The duration of mudjacking can vary depending on the size and complexity of the project. However, it typically takes a few hours to complete, and you can generally use the repaired surface within a day or two.
Mudjacking is a cost-effective solution for repairing sunken concrete and can be less expensive than replacing the entire slab.
Another option to consider is foam jacking. This method is similar to mud jacking, but instead of using a mixture of soil, water, and cement, it uses polyurethane foam to lift the concrete back into position.
Foam jacking is often preferred over mud jacking because it is less invasive, more precise, and more environmentally friendly since the foam is made from recycled materials.
The foam jacking cost may be slightly higher than mud jacking, but it can be a good option if you’re looking for a more precise and less invasive solution.
If the damage to your concrete is severe or if the concrete has become a safety hazard, consider replacing the entire slab. This can be costly, but it may be necessary in some cases.
Replacing a concrete slab involves breaking up the old concrete and pouring a new one to ensure a level surface. The cost of this method can vary depending on the area’s size and the project’s complexity.
To prevent future issues with concrete settling, there are several techniques that you can consider. One option is to install drainage systems to prevent water from accumulating beneath the concrete.
This is especially important if your property is located in an area with heavy rainfall or poor drainage. Another option is reinforcing the base with steel or other materials to provide additional support.
Regular maintenance and inspection can also help identify potential issues before they become significant problems. By taking these simple steps, you can ensure that your concrete remains safe, level, and functional for years to come.

In conclusion, it is imperative to address concrete raising promptly due to the numerous causes that can lead to concrete settlement, such as soil erosion, compaction, and poor drainage. These causes can result in uneven, sunken concrete surfaces, which can be hazardous and unsightly.
Fixes for concrete raising can vary depending on the severity and cause of the settlement, but some standard solutions include mud jacking, foam injection, and excavation and replacement.
It is important to note that ignoring concrete settling can lead to more severe and costly repairs down the line and potential liability issues if someone were to trip and fall on an uneven surface.
Therefore, it is highly recommended that a qualified professional address any signs of concrete settlement promptly to ensure the safety and longevity of the concrete surface.
