You’ve got some problematic concrete around your home creating tripping hazards and generally sloping in the wrong direction. You’re considering mud jacking to handle your issues but you know absolutely nothing about it. You really need a Mud Jacking 101 class, but that doesn’t exist, so an article will have to do.
Sounds like you need this Homeowner’s Complete Guide to Mud Jacking . . .
At Anchor Foundation Repair, we’ve been providing mud jacking services for sunken concrete in the Brazos Valley for decades and can tell you all about it. Who better to inform you about mud jacking than a company that does it all the time?
This guide will explore the mud jacking process, its benefits, potential drawbacks, costs, alternatives, and guidance on when mud jacking is an appropriate solution for your home’s concrete problem.
What Is Mud Jacking?
Mud jacking is a restorative concrete repair technique used to lift and level sunken or uneven concrete surfaces. It’s a cost-effective and efficient solution for addressing issues like uneven driveways, sidewalks, patios, pool decks, and other exterior concrete flatwork.
Mud jacking involves injecting a slurry mixture (made from water, topsoil, and Portland cement) beneath a sunken concrete surface to raise it back to its original position. The slurry reaches below the concrete via small holes drilled through the surface.
Once the slurry has dried and cured, it supports the concrete in the new position. Thus restoring its appropriate elevation and desired slope and prolonging the usefulness of the concrete for many years to come.

How Does Mud Jacking Work?
The mud jacking process is fairly simple and typically includes the following steps:
- Drilling Holes: Small, strategically placed holes (about 2 inches in diameter) are drilled into the affected concrete.
- Pumping Slurry: A slurry mixture composed of water, cement, and soil is pumped through the holes beneath the slab.
- Lifting the Slab: The injected slurry fills voids and exerts pressure, slowly lifting the concrete to its desired level. Drilling holes and pumping slurry to lift sections of concrete is repeated to gradually restore all portions of concrete to the appropriate elevation.
- Sealing Holes: After achieving the correct elevation, the drilled holes are patched with a concrete mixture to blend with the existing surface.
Typically, any walking surface can be used immediately after the mud jacking work is complete. Driveways or surfaces where heavier equipment is being stored should be given extra time to cure before use – several hours to one day would be ideal.
Mud jacking is quick and simple, getting you restored concrete in a short amount of time with little disruption, equivalent to a landscape crew working on your yard for the day.
Benefits of Mud Jacking
Mud jacking is a great option to improve sunken concrete surfaces that are otherwise in good condition. Benefits include:
- Cost-Effective: Mud jacking is significantly less expensive than removing and replacing concrete and often less expensive than comparable slab jacking techniques.
- Quick Process: Most mud jacking projects can be completed in a day or less, minimizing disruption of frequently used concrete around a home.
- Environmentally Friendly: This method reuses the existing concrete, reducing waste and environmental impact from disposal. Additionally, the materials used are naturally occurring components with no question of toxicity to the environment.
- Prevents Further Damage: By filling voids beneath the concrete, mud jacking helps prevent future settling and related issues, in addition to prolonging the overall useful life of the concrete surface.
Potential Drawbacks of Mud Jacking
Even solutions that seem pretty perfect will have their drawbacks, and mud jacking is not suitable for every concrete issue. Here are some potential downsides to this concrete lifting method:
- Not Suitable for Severely Damaged Concrete: Mud jacking is ineffective for flatwork with extensive cracking or deterioration.
- Material Erosion: The slurry used in mud jacking can be permeable to water and may erode over time.
- Injection Hole Visibility: The 2” patched site of the injection hole remains visible on some surfaces. An alternative method has smaller injection holes.
- Soil Conditions: In areas with very poor soil stability, mud jacking may not provide a long-term solution.
- Not Intended to Lift Concrete Beyond Original Position: If you’re hoping that mud jacking will raise your concrete to a higher level than it ever was, it won’t work well. But really, no concrete lifting method will accomplish that goal.

Alternatives to Mud Jacking
Mud jacking is not the only solution for repairing sunken concrete. Alternative solutions range from makeshift remedies to other slab jacking methods or full replacement.
- Polyurethane Foam Injection ( aka Polyjacking): This method uses expanding polyurethane foam to lift the concrete instead of slurry. It’s lighter and could be a more durable material, but it is generally more expensive than mud jacking. Other drawbacks include the use of chemicals and the potential for erosion around the foam material.
- Concrete Replacement: Removing and replacing the concrete is suitable for severely damaged surfaces but is at least double the cost, time-consuming, and disruptive to daily-use surfaces around your home.
- Self-Leveling Compounds: These are used for minor indoor fixes and are not suitable for significant outdoor applications.
- Other Low to No-Cost Alternatives: You can cover or hide the trouble spot, mark any tripping hazards with paint or tape, grind down high spots of concrete, or simply avoid the affected area. You could also remove the faulty concrete and replace it with gravel or other less costly material (grass, sand, mulch, pavers, etc.).

How Much Does Mud Jacking Cost?
The cost of mud jacking varies based on factors such as the size of the area, accessibility, and the extent of sinking. In the Central Texas area, typical costs range from $1,500 to $2,700 for the average scale project. For a larger-scale residential job, i.e., a large, two-lane driveway that’s sunken and needs a major lift, the cost would be closer to $7,000.
Compared to removing faulty concrete and replacing it with new, mud jacking usually runs about half the cost of full replacement. For example, lifting a 9-foot by 12-foot patio with mud jacking might cost around $900, whereas a full replacement could be approximately $1,800 or more.
Mud jacking can be more cost-effective for larger jobs than smaller ones. While polyjacking offers better savings on small-scale projects. For an in-depth cost comparison of mud jacking to polyjacking, we suggest this article: How Much Does It Cost to Level Concrete: Mud Jacking vs. Polyjacking.
How Long Does Mud Jacking Take?
Our average mud jacking projects typically require between half a day to a full day to complete. Larger-scale projects may take 2 or 3 days of work. The exact duration depends on factors such as the size and complexity of the area being repaired. This method is notably quicker than completely removing and replacing concrete surfaces.
When Mud Jacking Is an Appropriate Solution
Consider getting a bid for professional mud jacking services if your concrete is still in reasonably good condition and has life left in it. Signs that mud jacking is a viable solution for you:
- Uneven Surfaces: Visible sinking or tilting of concrete slabs.
- Pooling Water: Water accumulating in areas where it previously drained properly.
- Tripping Hazards: Significant height differences between adjacent slabs.
- Functionality Over Cosmetics: Safe and functional concrete is more important to you than a flawless surface appearance.
When selecting a contractor, inquire about their experience, request references, and obtain detailed estimates to ensure a reliable and satisfactory service. We always recommend looking for local contractors with longevity in business and overall positive online reviews and presence.
