Overview

Mudjacking, also called slabjacking, is the original method for lifting a sunken concrete slab. A crew drills holes through the concrete, then pumps a slurry of water, cement, and fine sand or soil into the space underneath. As the mix fills the void and builds pressure, it pushes the slab upward until it sits at the right height again.

Compared with polyurethane foam, mudjacking uses larger holes and a much heavier material, and the slurry needs time to cure before the slab carries its full load. In return, it is a widely available approach that handles large areas efficiently, and many homeowners like it for wide, older slabs where a little extra curing time is not a problem.

Birmingham's landscape is a common reason slabs need this kind of help. The red clay that covers the region swells with moisture and shrinks as it dries. Heavy storms send water racing down hillside driveways and along the edges of walks, washing fine material out from underneath. Over time the concrete is left bridging a gap it was never designed to span.

Your contractor can help you weigh mudjacking against foam or replacement for your own slab. Both lifting methods go after the same problem, filling the space beneath the concrete, and the better choice depends on size, condition, access, and how soon you want to use the surface again.

The number and pattern of holes depends on how large the slab is and how unevenly it has dropped. A good crew will walk the concrete with you before any drilling starts. Moving cars, planters, and patio furniture out of the way beforehand keeps the appointment on schedule.

Mudjacking tends to come up for larger, older slabs, such as a long driveway that climbs from the street, a wide patio, or a parking pad, where the goal is a well-tested fix. The extra density of the slurry can also be an advantage where the ground below is loose or has been disturbed by past grading.

As with any lifting approach, mudjacking works on the soil beneath the slab and not on damage in the concrete itself. If the surface is crumbling or split by many cracks in addition to sinking, the contractor may recommend addressing that separately or replacing the slab.

Some people assume an older method must be an outdated one. That is not how lifting works. The principle of filling a void and raising a slab has not changed, and a well-run mudjacking job today can perform well for many years.

Signs you need mudjacking

Any one of these is worth an on-site evaluation from the contractor we match you with.

  • A large slab, such as a full driveway or wide patio, has dropped fairly evenly
  • You want a traditional, widely used method for a big job
  • A contractor has confirmed the concrete is strong enough to lift as one piece
  • Overall project size matters more to you than same-day cure time
  • The ground below might benefit from the added density of a cement-based fill

How mudjacking works

Every job starts with an on-site evaluation from the contractor we match you with.

  1. 1
    Evaluate and plan

    The contractor inspects the slab and marks where holes are needed to reach the voids underneath.

  2. 2
    Drill the holes

    Holes roughly one to two inches across are drilled through the slab at each mark.

  3. 3
    Pump the slurry

    A cement-based mixture is pumped beneath the slab, filling gaps and gradually lifting the concrete.

  4. 4
    Monitor the rise

    The crew watches the slab as it moves and adjusts pumping to bring it level.

  5. 5
    Patch and cure

    Holes are patched, and the surface is left to cure before it takes regular foot or vehicle traffic.

Why homeowners choose it

Decades of track record
Mudjacking has been used for a very long time, so most concrete contractors know it well.
Suited to big slabs
Slurry can be pumped in volume, which suits long driveways, wide patios, and parking areas.
No demolition
Like foam, it lifts the slab you already have instead of breaking it out and repouring.
Dense fill
The heavier mixture can help stabilize ground that is loose or has been disturbed.
Widely offered
Because it is so established, many crews across Alabama already offer it.

Typical scenarios

Illustrative examples of the situations homeowners bring to us. They are not specific customer jobs.

ExampleA long hillside driveway raised in one day

Consider a Vestavia Hills homeowner whose sloped driveway has slowly sunk toward the street over a decade. After confirming the slab is structurally sound, a crew pumps slurry through a series of holes and brings the whole driveway back to grade in one working day.

ExampleA wide patio leveled section by section

Imagine an Alabaster patio made of several connected sections that have dropped by different amounts. The contractor lifts them in sequence so the seams line up, restoring a flat surface without replacing any concrete.

What affects your estimate

We cannot quote a price without seeing the job, but this is what typically goes into a contractor's written estimate.

  1. 1The total area to be lifted, since slurry is used by volume
  2. 2How far the slab has dropped and how much material it takes to fill the void
  3. 3Room for the pump truck and hoses to reach the work area, which can be tight on steep lots
  4. 4Whether several slabs, like a driveway, walk, and patio, are done in one visit
  5. 5Drainage or grading recommendations that come out of the evaluation

Keeping it level

A few habits that help a repair hold up over time.

  • Keep heavy vehicles off a fresh lift until the contractor says it has cured
  • Watch drainage near the slab, because standing water can undermine any fill over time
  • Have new cracks or renewed dips checked early instead of waiting
  • Ask what lifespan to expect for the soil on your particular lot
  • Reseal patched holes if they open up after a season of hard storms

Birmingham weather and your slab

Birmingham clay changes volume with moisture, and that movement is a big reason slabs settle unevenly. The heavier slurry used in mudjacking is often chosen because the added density resists shifting in some soil conditions.

Cure time can stretch in cold or soaking weather, so contractors may adjust their schedule during a wet spring or a rare hard freeze. If timing matters to you, ask how the season will affect your specific job before you book.

Myths vs. facts

Myth: Mudjacking is outdated and nobody does it anymore.
Fact: It remains a common, respected method, especially for large slabs where its record and material efficiency matter.
Myth: You cannot use the slab for days afterward.
Fact: Cure time varies with the mix and the weather, but many jobs are ready for light use well before several days pass. Your contractor will give you a specific timeline.
Myth: Mudjacking will crack a slab that is already weak.
Fact: A qualified crew evaluates strength first. If the slab cannot be lifted safely, they should recommend a different approach rather than risk more damage.
Myth: Mudjacking and foam always cost about the same.
Fact: Cost depends on the contractor, slab size, and site conditions for either method. No single answer applies to every job.

Frequently asked questions

What Birmingham homeowners ask about mudjacking.

It depends on the contractor, the slab size, and site access, so there is no reliable general answer. Ask your matched contractor for written estimates that compare both methods on your slab.
