Replacing Concrete vs. Lifting Concrete: Which is the Better Option?

Concrete is one of the most durable and widely used materials in construction, but over time, it can shift, crack, or settle due to soil movement, weather conditions, or poor initial installation. When this happens, homeowners and business owners often face a critical decision: should they lift the existing concrete using a method like mud jacking, or should they hire a concrete company to replace it entirely? While mud jacking may seem like a cost-effective solution, there are significant advantages to completely replacing concrete in many situations. Below, we’ll explore the pros and cons of each method and explain why replacing concrete is often the superior choice.

What is Mud Jacking?

Mud jacking, also known as slab jacking or concrete lifting, is a repair method that involves injecting a slurry mixture beneath a sunken concrete slab to lift it back to its original position. The slurry is typically made of cement, sand, and other additives that fill the voids under the slab and provide temporary support.

Pros of Mud Jacking:

  1. Lower Initial Cost: Mud jacking is generally less expensive than full concrete replacement in the short term, making it an attractive option for those on a tight budget.
  2. Quick Process: The process of lifting concrete can often be completed in a few hours, and the area can typically be used again within a day.
  3. Less Disruptive: Since mud jacking does not require breaking up and removing old concrete, it creates minimal disturbance to the surrounding area.

Cons of Mud Jacking:

  1. Temporary Fix: One of the biggest downsides of mud jacking is that it is not a permanent solution. Over time, the soil beneath the lifted slab can shift again, leading to further settling.
  2. Limited Load Capacity: Mud-jacked slabs may not be as strong as newly poured concrete, making them more susceptible to additional movement or cracking.
  3. Does Not Address Underlying Issues: If the cause of the settling is poor soil conditions or improper drainage, mud jacking does not fix the root problem—it only provides a temporary lift.
  4. Aesthetic Concerns: Mud jacking leaves small drill holes in the concrete surface, which can be unsightly and difficult to match to the existing slab.
  5. Inconsistent Results: The effectiveness of mud jacking varies depending on soil conditions, weather, and the quality of the materials used. It’s not always a one-size-fits-all solution.

What is Concrete Replacement?

Concrete replacement involves completely removing the old, damaged slab and pouring new concrete in its place. While this option requires more work and higher upfront costs, it offers a long-lasting and more reliable solution.  When the concrete is tore out, the concrete contractor has the ability to fix the subgrade at that time.  This will lead to a longer lasting concrete product that will not move up and down.

Pros of Concrete Replacement:

  1. Permanent Solution: Unlike mud jacking, replacing concrete provides a long-term fix. A new slab is structurally sound and built to last for decades.
  2. Stronger and More Durable: New concrete is reinforced and properly poured to ensure maximum strength and longevity, reducing the risk of future settlement.
  3. Fixes Underlying Issues: When concrete is replaced, contractors can address the root cause of settling, such as poor soil conditions or inadequate drainage, ensuring a stable foundation.
  4. Improved Aesthetics: New concrete looks clean and uniform, without the patchy appearance or drill holes associated with mud jacking.
  5. Better Return on Investment: While replacing concrete has a higher initial cost, it is a better long-term investment because it avoids repeated repairs and maintenance expenses.
  6. Customization Options: A new concrete installation allows for upgrades such as decorative finishes, stamped patterns, or color enhancements that improve curb appeal.

Cons of Concrete Replacement:

  1. Higher Initial Cost: Replacing concrete is more expensive upfront than mud jacking due to labor, materials, and installation time.
  2. Longer Installation Time: Concrete replacement takes longer because it involves breaking up old slabs, preparing the site, and allowing the new concrete to cure properly.
  3. More Disruptive: The process of removing old concrete and pouring new slabs can create noise, dust, and temporary access limitations to the affected area.

Why Concrete Replacement is the Better Choice

While mud jacking may seem appealing due to its lower cost and quicker turnaround, it is often a short-term fix that does not provide the stability and longevity of full concrete replacement. Here are some key reasons why replacing concrete is the better choice in most cases:

  1. Long-Term Savings: Although mud jacking is cheaper initially, the need for repeated repairs can add up over time. A new concrete slab provides a long-term solution that saves money in the long run.
  2. Structural Integrity: New concrete is stronger, more durable, and less prone to shifting compared to mud-jacked slabs, making it a more reliable choice for driveways, patios, sidewalks, and foundations.
  3. Increased Property Value: Well-maintained, newly poured concrete enhances the aesthetic appeal of a property, which can boost its value and attract potential buyers.
  4. Prevention of Future Issues: When replacing concrete, driveway contractors can improve site preparation by using proper grading, compacting the base, and reinforcing the slab with rebar or mesh to prevent future movement.
  5. Better Appearance: A brand-new slab looks cleaner and more uniform, avoiding the patchy or uneven look that sometimes results from mud jacking.

When is Mud Jacking a Viable Option?

While we strongly advocate for replacing concrete in most cases, there are situations where mud jacking might make sense, including:

  • Minor settling in non-load-bearing areas, such as small walkways or garden pathways.
  • When budget constraints prevent full replacement and a temporary fix is acceptable.
  • Situations where immediate usability is required, and waiting for concrete to cure is not an option.

Final Thoughts

If you’re dealing with sunken or cracked concrete, it’s essential to weigh the pros and cons of mud jacking versus full replacement. While mud jacking offers a quick fix, it does not address underlying problems and often requires repeat treatments. On the other hand, replacing concrete provides a permanent, structurally sound solution that improves durability, aesthetics, and long-term value.  It also allows you to add steel to your concrete for added strength.
