How long does mudjacking last?

In West Michigan, properly done mudjacking typically lasts 8–12 years under normal residential conditions. Poly foam tends to last longer in high-moisture environments.

Is mudjacking permanent?

It's not marketed as permanent because the underlying cause — soil movement under a slab — is an ongoing reality in Michigan's climate. That said, a well-done mudjacking job lasts long enough to be worth the cost many times over compared to replacement.

Can you mudjack concrete in the winter?

Only when ground temperatures allow the slurry to flow and cure properly. Frozen ground prevents the material from moving under the slab. We typically suspend mudjacking in deep winter (December–February) and resume in early spring, though mild winters can allow for earlier starts.

Why is my concrete sinking again after mudjacking?

If a slab that was previously mudjacked is settling again, it usually means the root cause — poor drainage, soil erosion, or active water movement beneath the slab — wasn't addressed after the first repair. Sometimes it means the first job wasn't done correctly. We can evaluate and advise on both.

What's the difference between mudjacking and slabjacking?

Nothing — they're the same process. "Slabjacking" is the more technical term; "mudjacking" is the common name for the same method using a cement-sand-water slurry.

Will mudjacking damage my concrete?

The drilling process creates holes, which are patched after injection. The injection pressure is controlled to lift — not crack — the slab. Properly done, mudjacking doesn't damage intact concrete. Very thin or already-cracked slabs carry more risk of additional cracking from the pressure.

Mudjacking in Grand Rapids and West Michigan

Mudjacking is the original concrete lifting method — and it still makes sense for a lot of residential jobs in West Michigan. If your driveway has dropped, your patio has settled, or your porch steps have pulled away from the house, mudjacking can bring them back to level for 50–70% less than tearing them out and starting over.

This page covers how mudjacking works, what it costs, where it makes sense, and where it doesn't — including an honest comparison with polyurethane foam, the newer alternative.

How Mudjacking Works

Mudjacking is sometimes called slabjacking — the terms mean the same thing. Here's the process:

1. Drilling: We drill holes through the concrete slab — typically 1.5 to 2 inches in diameter, spaced strategically based on where the slab has dropped and where we need to create pressure.

2. Pumping: A hydraulic pump forces a slurry beneath the slab through these holes. The slurry is a mix of Portland cement, topsoil or sand, and water — often incorporating fly ash or other fillers depending on the void size and application.

3. Lifting: As the slurry fills the void beneath the slab, it creates hydraulic pressure that pushes the slab up. The operator monitors the slab's position and controls the injection to lift it evenly and stop at the right level.

4. Patching: Once the slab is at the correct height, we patch the drill holes with a cement mix that matches the existing concrete as closely as possible. The patches are visible but blend in over a season or two of weathering.

5. Cleanup: Equipment comes off the driveway, the crew cleans up, and you're done.

Total time for a typical residential driveway: 2–4 hours. You can walk on it immediately. Wait 24 hours before parking vehicles on it.

What Mudjacking Costs in West Michigan

Mudjacking is priced by the job, not by the square foot, because the amount of material required depends on the size of the void — which you can't see until you start injecting. That said, here are realistic ranges for common jobs:

Job Type	Typical Range
Sidewalk panel (1–2)	$300–$700
Front porch / steps	$600–$1,500
Small patio (200–400 sq ft)	$800–$2,000
Standard driveway	$1,500–$3,200
Large driveway or multiple areas	$2,500–$4,500
Garage floor	$800–$2,000

Compare this to concrete replacement in West Michigan: $10–$15 per square foot installed after removal. A 500 sq ft driveway costs $5,000–$7,500 to replace. Most mudjacking jobs on that same driveway run $1,500–$3,000.

Mudjacking vs. Polyurethane Foam: The Real Difference

We use both methods, so we have no particular reason to favor one over the other. Here's an honest comparison:

Mudjacking is better when:

You want the most affordable option for a straightforward residential job
The void is large and would require a lot of poly foam (mudjacking material is significantly cheaper per cubic foot)
You're not in a hurry and 24-hour cure time is fine
The area is well-drained and moisture isn't a primary concern

Polyurethane foam is better when:

You need to drive on it the same day (1-hour cure vs. 24 hours)
The slab is near water — pools, drainage areas, or high-moisture zones — where the added water weight of mudjacking material could be a concern
Weight is a factor (poly foam weighs about 2–4 lbs per cubic foot; mudjacking slurry runs 100+ lbs per cubic foot)
The void is small and precise foam expansion is an advantage
Long-term durability is the priority and you're willing to pay more for it

Where Mudjacking Works and Where It Doesn't

Works well for:

Residential driveways — most common mudjacking application in West Michigan
Sidewalk panels (both public-adjacent and private)
Patio slabs not adjacent to pools
Porch and step leveling
Garage floors with moderate settlement
Interior commercial slabs in low-moisture environments

Not the right tool for:

Pool decks — the added weight of mudjacking material near a pool structure is a concern; poly foam is standard here
Areas with active water intrusion where the slurry would be washed away before curing
Slabs less than 3 inches thick with significant cracking — the pressure can cause additional cracking
Very large commercial voids where staged lifting and soil stabilization are needed first

Mudjacking in West Michigan: What the Soil Tells Us

West Michigan's sandy soils are part of why mudjacking works well here. Sand erodes gradually and creates voids over time — the kind that mudjacking is designed to fill. In areas with heavier clay content (which you find more in the eastern part of the lower peninsula), mudjacking slurry can sometimes have trouble flowing properly in high-clay voids.

Freeze-thaw is the other major factor. West Michigan averages a significant number of freeze-thaw cycles per year. Water beneath a slab freezes, expands, lifts the slab slightly, thaws, and the slab drops — but not always back to exactly where it started. Over 10–15 years, this produces the kind of gradual, irregular settling that mudjacking was designed to correct.

The Mudjacking Holes: What to Expect

The most common question we get: "Will I see the patches?"

Yes. The drill holes are 1.5–2 inches in diameter, and they're patched with a cement mix after injection. On new concrete, they're more visible. On older concrete that's already weathered and discolored, they blend in reasonably well within 6–12 months.

If you're bothered by the visual, poly foam uses smaller holes (5/8 inch) that patch more discreetly. We'll tell you about both options before you decide.
