Concrete Leveling

Sunken, uneven concrete slabs are a trip hazard and an eyesore — and in most cases, you do not have to replace them to fix the problem.

Why Does Concrete Sink in the First Place?

Concrete slabs do not sink on their own. Something underneath them changes, and the slab follows. In Laredo, the most common culprit is soil movement driven by the area's clay-heavy ground. Clay soil expands when it gets wet and contracts when it dries out. Over many wet-dry cycles, the soil beneath a slab can pull away and leave a gap, and the concrete drops to fill that void.

Other causes include poor compaction when the slab was originally poured, tree roots that have disrupted the soil, plumbing leaks that have washed material away from beneath the slab, or natural settling over years of use. Whatever the cause, the result is the same: a slab panel that sits lower than it should, creating an edge or gap that catches feet, scooters, and lawn mowers alike.

Understanding why the slab sank matters before deciding how to fix it. If there is an active leak under the slab, leveling it without addressing the leak means it will sink again within months. We always check for root causes before recommending a solution, and if a deeper fix is needed we will tell you upfront. For more extensive foundation or structural issues, our concrete slab and foundation work covers those situations in full.

How We Level Concrete: Your Options

Depending on how far the slab has dropped, the size of the void underneath, and the condition of the concrete itself, there are a few different approaches we use to restore a level surface:

Mudjacking (slabjacking): pumping a cement-soil slurry under the slab through small drilled holes to fill the void and lift the panel back into position
Polyurethane foam injection: injecting expanding foam through small holes to raise and stabilize the slab with less mess and faster cure time
Grinding high spots: when one panel has heaved above its neighbor, grinding the raised edge down creates a flush, safe transition
Partial slab replacement: when a panel is too cracked or damaged to lift successfully, removing and repouring just that section is the right call
Re-grading and repouring: for areas where repeated settling shows the base needs to be fully rebuilt before a lasting fix is possible

We walk you through which method makes the most sense for your specific slab, your budget, and the expected lifespan of the result. Lifting a slab that is already heavily cracked, for example, may not be worth the cost compared to replacing that panel. We will give you that honest comparison so you can decide with full information. If the uneven area is part of a larger concrete surface that needs attention, our concrete repair and replacement services can handle the full scope.

Where Concrete Leveling Makes the Biggest Difference

Sunken concrete shows up in a lot of places around a home or business. The most dangerous spots are the ones people walk across daily. A single sunken panel in your front walkway might not look like much, but it creates a lip that catches a toe at exactly the wrong moment. Driveways, patio slabs, pool decks, garage floors, and sidewalk sections are all common areas where leveling makes an immediate difference to both safety and appearance.

For commercial properties, uneven concrete near entrances, loading areas, and parking lots creates real liability exposure. A trip on your property because of a sunken slab is the kind of accident that is both preventable and expensive. Leveling those sections is one of the most cost-effective maintenance items a business owner can take care of.

Concrete Leveling Questions, Answered

Not sure what to expect? Call us at (956) 955-8166 and we will walk through your situation with you at no charge.

Is concrete leveling cheaper than replacing the slab?+

In most cases, yes. Lifting a slab that is still structurally intact typically costs 30 to 50 percent less than tearing it out and pouring new concrete. You also skip the curing wait time, since most leveling methods allow foot traffic within hours and vehicle traffic within a day or two. That said, if the slab has significant cracking throughout or the base beneath it is badly compromised, replacement may actually be the better long-term value. We will tell you honestly which situation you are in.

How long does a concrete leveling job take?+

Most residential leveling jobs are completed in a few hours on a single day. Commercial jobs with multiple sunken sections may take a full day. Mudjacking typically needs 24 hours before vehicle traffic. Polyurethane foam injection cures faster and can handle vehicle loads within a few hours. We will give you a specific timeline based on the method and size of your job before we start.

Will my leveled slab sink again?+

A leveled slab can re-sink if the root cause of the settling is not addressed. If the soil underneath is still losing moisture and compacting over time, or if a slow plumbing leak continues to wash material away, the slab may move again. That is why we check for the underlying cause before lifting. When the cause is stable soil settlement that has already finished moving, a leveled slab can hold its position for many years without any further issues.

Stop ignoring that sunken slab. Call Laredo Concrete Company and get it fixed the right way.
