Is mud jacking or polyurethane better?
At Du-West Services, we’ve walked through hundreds of yards with homeowners scratching their heads over sinking concrete. Driveways that look like roller coasters. Sidewalks trying to trip you. Patios with one corner aiming for the center of the earth. The big question we get is: Should I go with mud jacking or polyurethane injection?
Both lift sinking slabs, but they take different roads to get there. Let’s break it down, step-by-step, and help you figure out which solution fits your home, your soil, and your budget.
What Is Mud Jacking?
Mud jacking—also called slab jacking—involves pumping a thick slurry (a mix of water, soil, sand, and cement) underneath the sunken concrete. The pressure from the slurry lifts the slab back into place.
It’s been around for decades and works well for heavier concrete like sidewalks, steps, and some driveways.
The Process:
- We drill a few small holes into the slab.
- We pump in the slurry until the slab rises back into position.
- We patch the holes with concrete and clean up the area.
Pros:
- Cost-effective
- Time-tested method
- Great for large slabs and heavy sections
Cons:
- Heavier fill material may settle again
- Larger holes drilled into the slab
- Longer drying time (sometimes up to 24 hours)
What Is Polyurethane Injection?
Polyurethane injection uses expanding foam instead of slurry. It starts as a liquid, then quickly expands to fill the voids beneath your slab and lifts it. The material is lightweight but strong—and it doesn’t wash out with water.
The Process:
- We drill smaller holes than with mud jacking.
- We inject the polyurethane foam.
- The foam expands in seconds and lifts the slab.
- We patch the holes and check for evenness.
Pros:
- Smaller holes (less patching)
- Fast cure time (usually under 30 minutes)
- Lightweight material that won’t add extra weight
- Moisture-resistant and long-lasting
Cons:
- More expensive than mud jacking
- Not always ideal for thicker, heavier concrete sections
So, Which Is Better?
It depends on what you’re fixing—and what you’re comfortable with.
Use Mud Jacking If:
- You’re working on large, heavy slabs like garage floors or long driveways.
- You’re looking for a budget-friendly solution.
- You don’t mind a longer wait time before walking or driving on the area.
Use Polyurethane Injection If:
- You want fast results with minimal mess.
- You’re lifting patios, pool decks, or interior floors.
- You need a fix in areas with poor drainage or wet soil.
- You’re looking for something that won’t settle again anytime soon.
Still not sure? That’s what we’re here for. When you want the best, call Du-West. We’ll come out, take a look, and walk you through your options without sugarcoating anything.
When Should You Call a Professional?
Don’t wait until your slab sinks so far it cracks or causes someone to trip. Call us if you notice:
- A sinking or uneven patio, sidewalk, or driveway
- Water pooling in strange places
- Cracks spreading across the surface
- Gaps between your steps and front porch
- A garage floor that’s sloping to one side
These aren’t “wait-and-see” problems. They get worse with time—and more expensive.
What Happens When We Show Up
We’re not the kind of crew that rolls up, shrugs, and hands you a quote on a napkin. We get into the details. Here’s how we do it:
Step 1: Inspection
We inspect the area, check for voids under the slab, and identify where and why it’s sinking. We use levels, probes, and sometimes ground radar to get the full picture.
Step 2: Recommendation
We explain the pros and cons of each method—no pressure, no sales pitch. If your slab needs foam, we say foam. If it’s better off with mud, we go with mud.
Step 3: The Work
We drill, inject, lift, and patch—usually all in the same day. Most jobs take just a few hours. Poly jobs dry lightning fast. Mud jobs need a bit more time.
Step 4: Post-Lift Review
We walk the slab with you, confirm levelness, and answer any questions. No guesswork. No wondering.
FAQ
Will my concrete look the same afterward?
We patch the holes, but they won’t disappear completely. Poly foam leaves smaller holes, so it’s usually less noticeable.
How long does it last?
Polyurethane can last decades. Mud jacking may eventually need to be redone if the soil keeps shifting, but both methods hold up well if the area is stable.
Can you lift a cracked slab?
Yes, but the crack may not close completely. We’ll advise whether lifting or full replacement is the better route.
Is it safe to walk or drive on afterward?
For poly foam—usually within 30 minutes. Mud jacking takes longer, typically 12–24 hours.
