Why Your Slab Is Still Sinking: Scritchlow Concrete Lifting and Slab Jacking Exposes the Heavy Lie Behind Mudjacking

If your concrete keeps sinking, the problem might not be the ground—it might be the mud you paid someone to pump under it.

The Real Problem with Mudjacking

Let’s talk about mudjacking—the old-school fix that sounds solid because, well, it’s full of mud, sand, cement, and water. Heavy stuff. You’d think that’s a good thing, right? You’ve got a sunken sidewalk or driveway, someone shows up, drills holes, and pumps in this thick slurry to lift it back up. Boom. Looks level. Problem solved.

Except it’s not.

Here’s the kicker most folks don’t realize: that mixture? It’s really heavy. We’re talking 100+ pounds per cubic foot. And it gets pumped underneath your already sinking slab—which means you’re adding even more weight to the soil that couldn’t support the slab in the first place.

Outdated Methods That Make Things Worse

The root cause? That slurry mix is gravity-fed and lacks the precision or consistency to control how and where it expands. So you end up with uneven lifts, unpredictable results, and a ticking time bomb under your feet. It’s a messy, outdated process that treats the symptom—not the cause—and leaves you with the same problem a few seasons later.

“Foam is Too Light?” Think Again.

Now, I know what you’re thinking: “Wait, so what’s the better option—foam?”

And your brain immediately says, “That stuff sounds way too lightweight to hold up concrete, let alone keep it level long-term.”

Totally fair.

But here’s the reality: this isn’t packing peanuts or dollar-store pool noodles. We’re talking high-density polyurethane foam—a material so tough and reliable that the U.S. Department of Transportation uses it to lift highway slabs weighing over 50,000 pounds.

Time for a Belief Shift

This foam is engineered for strength, formulated for control, and trusted to perform under massive stress. And unlike mud, it doesn’t add weight—it expands rapidly to fill voids, locks in place, and cures in minutes. It’s like precision surgery for your concrete.

So instead of dragging around that old belief that “heavier is better,” it’s time to adopt a more modern—and smarter—mindset:
“This foam is stronger, longer-lasting, and doesn’t make the problem worse.”

The New Method: Foam Lifting That Works

Here’s how the foam works—and why it’s miles ahead of the old way:

• We drill smaller holes (about the size of a dime—no joke) into the slab.
  
• Then we inject the high-density foam.
  
• As it expands, it gently but powerfully lifts the concrete with surgical precision.
  

It cures in minutes, not days. You can walk or drive on it the same day. And it’s waterproof, so it won’t erode or wash away when the next Illinois rainstorm rolls through.

Bottom line?
You get a stronger, longer-lasting fix—with less mess, less downtime, and way fewer callbacks.
