Commerce City sits in Adams County on clay-heavy soils that expand when wet and shrink during dry spells. This cycle drives sunken and uneven concrete throughout neighborhoods like Reunion, Derby, Buffalo Run, Rose Hill, and Dupont. Colorado's freeze-thaw cycles make it worse each winter. This FAQ page covers what mudjacking can and cannot do to help you make a smarter decision before spending money on full concrete replacement.

What Can Mudjacking Do for My Concrete?


Mudjacking lifts and re-levels sunken concrete slabs by filling voids beneath them with a cement-based slurry. Here is how the work gets done:


1. A technician inspects the slab and assesses settling and cracking.

2. Small access holes are drilled through the concrete at strategic points.

3. A Portland cement-based slurry is pumped under pressure through the holes, filling voids and lifting the slab.

4. The slab is raised back to its original grade and the holes are patched.

5. The area can typically be used again shortly after completion.


CrackerJack uses a topsoil and sand mixture combined with Portland cement, which resists shrinkage and provides lasting support. You can see results from past jobs in the past projects gallery.


Frequently Asked Questions

  • What Surfaces Besides Driveways Can Mudjacking Lift?

    Mudjacking can lift most exterior and interior concrete slabs. Sidewalks, patios, garage floors, basement slabs, pool decks, porches, steps, and walkways are all surfaces the process can address. If a slab has settled because soil washed away or compacted beneath it, mudjacking may be a practical repair option.

  • How Much Settling Can Mudjacking Correct?

    Mudjacking can often correct several inches of settling, depending on slab condition and void size. The process fills the void completely rather than simply propping the slab, which helps prevent future movement. A free on-site estimate will confirm whether the drop on your specific slab falls within a correctable range.

  • Can Mudjacking Raise a Driveway Section Where It Meets the Garage?

    Yes. The transition between a concrete driveway and a garage apron is one of the most commonly repaired spots. Water channels along this joint, eroding soil underneath over time, and the resulting drop creates a lip that can damage vehicles and pose a tripping hazard. Mudjacking can lift that section back flush with the garage floor in most cases.

  • Can a Driveway With Large Cracks or Missing Chunks Be Mudjacked?

    It depends on the condition. Minor to moderate cracking does not automatically rule out mudjacking. However, if sections are broken into many small pieces or structurally compromised, replacement may be the better path. CrackerJack provides an honest evaluation at no charge, including a clear recommendation when mudjacking is not the right fit.

  • How Much Does Concrete Leveling Cost in Colorado?

    Every job varies by slab size, degree of settling, number of holes required, and access, so no single price applies here. This FAQ page exists in part to set those expectations early. CrackerJack offers free on-site estimates so you know what to expect before any work begins. Call (303) 410-7787 to request your quote.

  • How Do I Know if My Driveway Can Be Mudjacked or Needs Replacement?

    A slab that is settled but structurally intact is generally a good mudjacking candidate. Signs that replacement may be necessary include severe fragmentation, widespread surface deterioration, or pieces too small to lift cleanly. When a slab can be saved, mudjacking costs significantly less and avoids the disruption of full demolition and repour.

  • Do I Need a Geotechnical Report Before Mudjacking a Driveway?

    Residential mudjacking projects typically do not require one. The technician evaluates soil and slab conditions as part of the free on-site estimate. For larger commercial or municipal projects, more detailed assessment may be appropriate. Learn more about the process on the mudjacking vs. polyurethane page.

  • What Should I Check Before Hiring a Mudjacking Contractor?

    Confirm the contractor is fully insured, uses a cement-based slurry rather than polyurethane foam, and backs their work with a warranty. CrackerJack carries full insurance, uses eco-friendly cement-based materials mixed on site, and backs all work with a two-year warranty and a satisfaction guarantee. The company holds an A+ BBB rating and has earned Angie's List Superior Service recognition.
