MUDJACKING & CONCRETE LEVELING

Sunken Slab Repair and Concrete Leveling in Broomfield, CO

Broomfield sits in the gap between Denver and Boulder, and its concrete tells the story of the building boom that filled that gap. Subdivisions off the Northwest Parkway and around Interlocken were built fast through the 2000s, and the fill dirt under driveways and patios in those neighborhoods is still settling two decades later. When a slab sinks instead of cracking outright, mudjacking gets it back to grade in an afternoon instead of a demolition crew.

Broomfield became Colorado's only consolidated city and county government in 2001, but the ground under it never got the memo. Neighborhoods around Interlocken, Anthem, and the Broadlands went up fast through the late 1990s and 2000s on what had been open prairie between Denver and Boulder, and the fill packed under driveways and patio slabs in those subdivisions is still settling. Where the fill was compacted a little light, or where a downspout has been draining to the same low spot since the house was built, that gradual settling shows up as a slab that has dropped an inch or two below the walkway or garage floor next to it. The soil under a lot of Broomfield sits close to the transition between the heavier bentonite clay common in the Denver basin and the sandier ground closer to Boulder County, and both react to moisture. Add the freeze-thaw swings Broomfield gets most winters, dozens of them between November and March, and any water sitting under a slab edge works the sub-base loose a little more each season. By the time a homeowner near US-36 or the Northwest Parkway notices a driveway settling unevenly, the void underneath has usually been growing for a while.

Our Mudjacking & Concrete Leveling Approach

Concrete Doctor lifts Broomfield slabs with the mud slurry pump method. We drill small ports, roughly 1 to 2 inches across, through the settled concrete, then pump a cement-based slurry underneath at pressure. That slurry fills the void left by eroded or under-compacted fill, and the hydraulic pressure raises the slab back toward its original grade. Once the level is right, the ports get patched flush and the surface is ready to use, usually the same day or the next morning. Before we drill anything, we check the slab itself. A slab that has settled evenly and is still structurally sound is a good candidate for lifting. A slab that's cracked into several pieces, heaved upward instead of sunk, or sitting over soil that's still actively moving is not, and we'll say so rather than lift something that won't hold. Lifting work carries a one-year warranty, and where a driveway or patio also has open cracks or failed joints, we can address those with elastic polyurethane in the same visit.

Interlocken's Commercial Flatwork Can't Afford a Long Closure

Interlocken's office parks and the retail flatwork around Flatiron Crossing see heavy daily foot and vehicle traffic, and a sunken loading dock apron, sidewalk panel, or parking lot section is both a liability risk and an inconvenience a business can't just shut down to fix. Tear-out and replacement means barricades, curing time, and a section of parking or walkway out of service for days. Mudjacking lifts the existing slab in a matter of hours and it's typically load-ready the same day, which matters when a property manager can't close half a lot during business hours. We've lifted commercial flatwork that settled for the same reasons residential slabs do, mainly fill that wasn't compacted to spec during the original build-out, but on a larger footprint the settling is often more visible because more traffic crosses it every day. A trip-hazard panel outside an office entrance or a dipped apron at a loading dock gets flagged fast by whoever manages the property, and getting it fixed without a lengthy closure is usually the deciding factor in choosing lifting over replacement.

Why Backfill Around Broomfield's 2000s Subdivisions Keeps Moving

A lot of Broomfield's housing stock, especially in the neighborhoods built out through the late 1990s and 2000s, sits on lots where a significant amount of fill dirt was brought in and graded before the slabs were poured. When that fill isn't compacted correctly at the time, it keeps settling under its own weight for years, and every freeze-thaw cycle and every heavy rain nudges it a little further. Driveways, garage aprons, and patio slabs poured directly on that fill are the first things to show it, because they're rigid and unforgiving compared to the soil moving underneath them. This is a slower, steadier kind of settling than the seasonal clay-heave more common in Broomfield's older, established pockets, and it's part of why mudjacking works so well for it. The slurry fills the actual void left by the settling fill, restoring support rather than just filling a crack, and the slab stays level going forward as long as drainage around it is managed.

Frequently Asked Questions

Most residential lifts are a single visit that takes a few hours from start to finish, including drilling the ports, pumping the slurry, and patching the holes flush. The driveway is usually ready to drive on the same day or by the next morning. We'll give you an exact window during the free estimate once we've seen the slab and how far it needs to rise.

In most cases, yes. Fill settlement leaves a void or loose zone under the slab that slurry is designed to fill, which is exactly the kind of settling mudjacking handles best. We check the slab's condition first, since a slab that's cracked into multiple pieces on top of the settling may need repair or partial replacement instead.

We lift driveways, sidewalks, patios, porch and stoop steps, garage slabs, basement floors, and pool decks, depending on the slab's condition. If you've got more than one settled slab on the property, we can usually address them in the same visit.

Lifting work carries a one-year warranty. If drainage around the slab is also part of what caused the original settling, we'll flag that during the free estimate so it doesn't undo the work.
