Mudjacking in Colorado Springs, CO: Cost and How It Works (2026)
If a section of your driveway, patio or front walk in Colorado Springs has sunk or tilted, mudjacking, also called slabjacking, is usually the fastest and most affordable way to lift it back into place without tearing out the concrete. It's especially common in neighborhoods like Old Colorado City and Fountain, where decades of fill settlement and claystone soil movement have left driveways and sidewalks uneven. This guide covers how mudjacking works, what it costs around the metro, and when a sunken slab is a simple flatwork fix versus a sign of something bigger with your foundation.

Why concrete sinks in Colorado Springs
Much of the metro sits on claystone and bentonitic clay derived from the Pierre Shale, soil that shrinks when dry and swells when wet. Flatwork poured over disturbed, backfilled soil during construction is especially prone to settling unevenly as that fill consolidates over the following years.
In older parts of town like Old Colorado City, decades-old utility trenches and foundation backfill create sunken sidewalk panels and driveway aprons. In Fountain and parts of the Powers corridor, newer graded lots with cut-and-fill construction can settle at different rates across a single slab, causing a visible tilt at the garage threshold or patio door.
How mudjacking works
Mudjacking pumps a slurry of soil, cement and water through holes drilled into the slab, filling voids underneath and lifting the concrete back toward its original grade. It's a well-established, lower-cost-per-square-foot method that's been used in Colorado Springs for decades, and it remains a common choice for larger driveway and patio jobs where per-square-foot cost matters most.
The tradeoff is that the added weight of the slurry can, in some cases, encourage renewed settling faster than a lighter alternative if the claystone beneath is still actively moving, so ask your contractor whether they're also addressing the drainage or moisture issue that caused the original settlement.
Mudjacking versus polyurethane foam
Polyurethane foam injection cures in about 15 minutes, adds far less weight to the soil, and resists moisture, which matters given how much Colorado Springs's claystone reacts to water. It typically costs more per square foot than mudjacking but can be the better choice on soil that's still actively shrinking and swelling.
Most local concrete leveling companies offer both, and the right choice often comes down to slab size, budget, and how active the soil movement underneath still is.
When mudjacking isn't enough
If the sunken slab is a covered patio poured against the house foundation, or if you're also seeing cracks inside the house or doors sticking, have a contractor rule out structural foundation movement before leveling the flatwork. A slab attached to a foundation with active heave or settlement may need piers, not just mudjacking.
Repeat settling in the same spot after a previous mudjacking job usually points to an unresolved drainage or erosion issue feeding water under the slab, not a flaw in the method itself.
What mudjacking costs in Colorado Springs
Pricing depends on slab size, how far it needs to lift, and access. The ranges below reflect current Colorado Springs metro quotes for common flatwork jobs.
Hiring a mudjacking contractor here
Confirm the contractor's Pikes Peak Regional Building Department license class if the project also touches structural elements, and ask for a couple of recent local references, ideally jobs in a neighborhood with similar soil, like Old Colorado City or Fountain. For structural foundation concerns beyond flatwork, see the Colorado Springs foundation repair hub, and if you'd rather skip the search entirely, request a vetted match through Homeowner Henry's get-matched form for foundation repair.

Common questions
How long does mudjacking last in Colorado Springs?
A properly done mudjacking job can last 10 years or more, but Colorado Springs's active claystone soil means repeat settling is more likely here than in areas with more stable soil, especially if drainage issues aren't also corrected.
Is mudjacking cheaper than polyurethane foam leveling?
Yes, mudjacking is typically less expensive per square foot upfront, which is why it remains popular for larger driveway and patio jobs in Colorado Springs, though foam can be worth the added cost on soil that's still actively shrinking and swelling.
Does mudjacking require a permit in Colorado Springs?
Routine flatwork mudjacking on a driveway or patio typically doesn't require a Pikes Peak Regional Building Department permit, but if the slab is structurally tied to the foundation or part of a larger repair, check with PPRBD directly using their plan-type lookup.
Can mudjacking fix a sinking garage slab?
Often yes, if the sinking is due to fill settlement under the slab rather than movement of the house's structural foundation. If the garage slab is monolithic with the foundation wall or you're seeing related cracks in the house, get an inspection before assuming mudjacking alone will fix it.
