Foundation Piering vs. Mudjacking (Slabjacking)

Our Verdict

Piering and mudjacking solve fundamentally different problems. Mudjacking is the right choice for minor slab leveling on stable soil — it's fast, affordable, and effective for driveways, sidewalks, and patios. Foundation piering is required for actual structural foundation settlement, especially on expansive soils. Using mudjacking to address a structural foundation problem is like putting a band-aid on a broken bone — it may look better temporarily but doesn't fix the underlying issue. When in doubt, get a structural engineer's opinion ($300-$500).

Quick Comparison

Factor Foundation Piering Mudjacking (Slabjacking)
Cost Range $5,000 – $25,000 $500 – $3,000
Average Cost $12,000 $1,500
Duration 2-5 days 2-6 hours
Longevity 25+ years (lifetime with steel piers) 5-10 years
Best For Significant foundation settlement, structural damage, homes on expansive clay soils, or any situation requiring permanent stabilization Minor concrete slab settling (sidewalks, driveways, garage floors, patio slabs), cosmetic leveling of small areas, and situations where the soil is stable but the slab has sunk
Warranty Lifetime transferable warranty (steel piers); 10-25 years (concrete piers) 1-3 year warranty typical; some offer 5 years

Foundation Piering: Pros & Cons

Permanent foundation stabilization reaching bedrock or stable soil
Can lift and re-level a settled foundation
Works on all foundation types (slab, pier and beam, basement)
Lifetime warranty available with steel push piers
Does not add weight to already stressed soil
Engineering-backed solution for structural problems
Significantly more expensive ($1,000-$3,000 per pier)
Requires excavation around the foundation perimeter
Takes 2-5 days compared to hours for mudjacking
Minor landscaping disruption around pier installation points
Requires a structural engineer's assessment for proper design

Mudjacking (Slabjacking): Pros & Cons

Much lower cost ($3-$6 per square foot)
Fast — most jobs completed in a few hours
Minimally invasive (small drill holes that are patched)
Effective for leveling sunken concrete slabs
Good for driveways, sidewalks, patios, and pool decks
No excavation required
Not a permanent fix — the added weight can cause re-settling
Cannot address the root cause of foundation settlement
Not suitable for structural foundation problems
Added material weight (cement slurry is heavy) stresses weak soil further
Shorter lifespan — may need to be repeated every 5-10 years
Not effective on expansive clay soils that continue to shift

Frequently Asked Questions

Can mudjacking fix a sinking house foundation?
Mudjacking can temporarily level a sinking slab foundation, but it doesn't address why the foundation is sinking. If the underlying soil is weak, expansive, or poorly compacted, the added weight of the cement slurry will likely cause the slab to sink again. For structural foundation settlement, piering is the appropriate repair.
How many piers does a typical foundation repair need?
Most residential foundation repairs require 6-15 piers, depending on the size of the home and extent of settlement. At $1,000-$3,000 per pier for steel push piers, a typical project runs $8,000-$25,000. A structural engineer determines the exact number and placement based on soil conditions and load requirements.
Is mudjacking the same as polyurethane foam injection?
No. Mudjacking uses a heavy cement slurry pumped under the slab. Polyurethane foam injection (polyjacking) uses lightweight expanding foam. Polyjacking is lighter (reducing re-settling risk), more precise, and faster-curing, but costs 50-100% more than traditional mudjacking. See our mudjacking vs. polyurethane comparison for details.
Do I need a structural engineer before choosing a repair method?
For any foundation issue beyond a minor cosmetic slab settlement, yes. A structural engineer ($300-$500 for an inspection) can determine whether you have a structural problem (needs piering) or a surface-level issue (mudjacking may suffice). This assessment prevents you from paying for the wrong repair.
