Mudjacking & Concrete Slab Leveling in New York City
Professional slab lifting and leveling for suitable settled concrete surfaces, helping restore more even elevations without automatically replacing the entire slab.
Lifting and Leveling Settled Concrete Slabs
Concrete slabs can settle over time when the material beneath them loses support, shifts or contains voids. This can leave adjacent surfaces at different heights.
Mudjacking is a slab-lifting method used in suitable situations to raise settled concrete and improve alignment with surrounding surfaces.
Whether lifting is appropriate depends on the condition of the concrete, amount of settlement, underlying support and the function of the slab.
Common Concrete Settlement Conditions
Mudjacking is generally considered where an existing slab has settled but remains suitable for lifting rather than complete replacement.
Uneven Walkways
Settled concrete can create different elevations between adjacent walkway sections.
Sunken Slabs
Concrete that has dropped below its original level may be suitable for lifting depending on its condition.
Settled Patio Areas
Patio slabs can settle as underlying support conditions change over time.
Drainage-Related Slopes
Settlement can alter the intended slope of concrete and affect the way surface water moves.
Voids Beneath Concrete
Loss of support beneath a slab can contribute to settlement and uneven surface levels.
Localized Settlement
Where only part of a concrete area has dropped, leveling may be considered before full replacement.
Supporting and Raising a Settled Concrete Slab
Mudjacking generally involves introducing a lifting material beneath a suitable settled slab through access points in the existing concrete.
As the material fills voids and builds support beneath the slab, controlled pressure can raise the concrete toward the required elevation.
The suitability of the method depends on the slab condition and underlying circumstances. Severely deteriorated or structurally unsuitable concrete may require another repair approach.
Areas Where Slab Lifting May Be Appropriate
The condition of the slab should be reviewed before deciding whether lifting or replacement is the better approach.
Concrete Paths
Lifting appropriate settled walkway slabs to improve alignment with adjacent surfaces.
Patios
Leveling suitable concrete patio sections affected by localized settlement.
Concrete Aprons
Correction of suitable settled concrete areas where slabs meet other surfaces.
Exterior Slabs
Leveling of appropriate exterior concrete slabs around residential and commercial properties.
Sloped Concrete
Settlement-related elevation changes may sometimes be corrected to improve surface alignment.
Suitable Concrete Areas
Selected commercial slab areas may be considered for lifting depending on construction and condition.
Concrete Leveling for New York City Properties
Settlement conditions vary depending on the concrete, underlying support and surrounding site.
Residential Properties
Suitable exterior concrete areas around homes and residential buildings.
Brownstones & Townhouses
Selected exterior concrete areas associated with older New York City properties.
Multifamily Buildings
Concrete leveling for appropriate common exterior slab and access areas.
Commercial Properties
Slab lifting for suitable exterior concrete areas associated with commercial properties.
A Controlled Concrete Leveling Process
Before lifting a slab, its condition and pattern of settlement should be considered.
Review the Slab
Settlement, cracking and the condition of the existing concrete are considered.
Determine Suitability
The slab is considered for lifting versus repair or replacement.
Controlled Lifting
Material is introduced beneath suitable areas to improve support and elevation.
Check the Finished Level
The adjusted slab is reviewed in relation to adjacent concrete and surrounding surfaces.
Not Every Settled Slab Is Suitable for Mudjacking
Mudjacking addresses elevation and support beneath suitable concrete, but it does not restore concrete that is severely cracked, crumbling or extensively deteriorated.
Where the slab itself is damaged, concrete repair or replacement may be more appropriate. The existing condition should therefore be considered before selecting a solution.

Request an EstimateFrequently Asked Questions
What is mudjacking?
Mudjacking is a concrete leveling method used to lift suitable settled slabs by introducing supporting material beneath the concrete.
What causes concrete slabs to sink?
Settlement can occur when the material beneath a slab loses support, shifts, washes out or contains voids.
Can every sunken slab be lifted?
No. The concrete needs to be suitable for lifting. Severely cracked, crumbling or structurally damaged slabs may require repair or replacement instead.
Can mudjacking fix cracked concrete?
Mudjacking primarily addresses support and elevation. Existing cracks may still require separate concrete repair depending on their condition.
Is mudjacking the same as concrete replacement?
No. Mudjacking attempts to retain and lift the existing slab, while replacement involves removing and installing new concrete.
How do I know whether my slab should be lifted or replaced?
The decision depends on the amount of settlement, cracking, deterioration, slab condition and the support beneath the concrete.
