Why Mudjacking Isn’t the Best Fix for Sunken Concrete

Table of Contents

Have you ever noticed an uneven sidewalk, a sinking driveway, or a garage floor that just doesn’t seem to be level anymore? It’s a common problem, but deciding on the right fix can be tricky. One of the most popular solutions out there is mudjacking, but is it really the best fix for sunken concrete? Today, we’re breaking down why mudjacking might not be your best option and exploring what alternatives can offer you a longer-lasting solution.

What is Mudjacking?

To start, let’s understand what mudjacking is. Mudjacking involves drilling holes in the sunken concrete slab and pumping a mixture of cement, soil, and water (called “mud”) beneath the slab to lift it back into place. While this method can raise the concrete, it’s not always the most reliable or durable option, especially for larger, more significant repairs.

Why Mudjacking Isn’t Always the Best Fix for Sunken Concrete

1. Limited Effectiveness for Severe Sinking

When it comes to severe cases, mudjacking might not be the best solution for a sunken concrete problem. For instance, if your sidewalk, garage floor, or driveway has dropped by 10 inches or more, the amount of material and effort required to lift it back up can become impractical. In cases like these, mudjacking could end up being just as expensive as tearing out and repouring the concrete entirely.

Instead of pouring resources into a temporary fix, sometimes the more cost-effective approach is to consider a full replacement. This way, you’ll have a completely new, level surface that’s built to last. That’s why, when looking for the best fix for sunken concrete, evaluating the severity of the drop is crucial.

2. Short-Term Solution for Large Areas

Mudjacking is often a quicker and cheaper fix when dealing with smaller, less significant issues. If your driveway has only dropped an inch or two, mudjacking might work temporarily. However, if you’re dealing with larger sections—such as a big 12-foot by 30-foot section—it might be more cost-effective to look at longer-term solutions. Releveling such a large space using mudjacking may not last as long as you’d hope, making it a less effective choice for substantial repairs.

Polyjacking: A More Reliable Alternative

How Polyjacking Works

Instead of the traditional mud mixture used in mudjacking, polyjacking utilizes a polyurethane foam injected beneath the slab to lift and level it. This foam expands, fills voids, and provides a more stable foundation. Unlike mudjacking, polyjacking offers a cleaner, quicker, and longer-lasting result.

Why Polyjacking Is Often a Better Choice

  • Better Stability: Polyjacking provides a more stable lift that won’t settle as quickly over time.
  • Lightweight Material: The polyurethane foam is lightweight, reducing the risk of further sinking.
  • Fewer Drilled Holes: Since polyjacking requires fewer holes, it minimizes damage to your existing concrete.

When Should You Consider a Full Replacement?

  1. Significant Damage or Buckling: If the concrete is buckled or dropped by more than 10 inches, it’s usually more practical to remove and replace the slab.
  2. Large Sections with Severe Sinking: For large driveway sections or garage floors with significant sinking, a full tear-out and repour might be the best fix for sunken concrete in the long run.

Comparing Costs: Mudjacking, Polyjacking, and Full Replacement

When deciding which option is right for you, it’s essential to consider the costs involved.

Mudjacking:

  • Cost: Approximately $1,400 to $1,500 for smaller projects
  • Longevity: Shorter lifespan, especially for larger or heavily used areas

Polyjacking:

  • Cost: Slightly more than mudjacking, but provides a much more stable and long-lasting solution
  • Longevity: Can last much longer due to the stability and strength of the polyurethane foam

Full Replacement:

  • Cost: The most expensive option upfront, but the longest-lasting solution
  • Longevity: Provides the most durable and effective fix for severely sunken concrete

In Summary

If you’re dealing with a sunken concrete issue, it’s essential to weigh your options carefully. Mudjacking might be a quick fix, but it’s not always the best fix for sunken concrete, especially when the damage is severe or covers a large area. Considering alternatives like polyjacking or even a full replacement might save you more time and money in the long run. If you’re unsure about which option is right for you, we’re here to help.
