Settling Concrete? Eliminate Trip Hazards and Drainage Problems
Uneven concrete creates liability, directs water toward foundations, and worsens over time. Fix it right with leveling or replacement.
Get Free AssessmentTrip Hazard Liability
Property owners are liable for injuries from uneven walkways. Even 1/2" differences cause falls.
Progressive Damage
Settlement worsens over time. Early intervention costs less than delayed repair.
Water Damage Risk
Settled slabs redirect water toward foundations, causing basement leaks and structural issues.
Why Concrete Settles
Understanding the cause determines the right repair approach
Poor Subbase Compaction
Soil not properly compacted during original installation continues to settle under the slab weight, creating uneven surfaces.
Water Erosion
Water flowing beneath the slab washes away supporting soil, creating voids that cause concrete to drop into empty spaces.
Freeze-Thaw Cycles
Water beneath slabs freezes and lifts concrete, then thaws and settles unevenly. Repeated cycling causes progressive settlement.
Organic Decomposition
Buried tree roots, leaves, or organic fill material decomposes over years, leaving voids beneath the concrete.
Heavy Loads
Loads exceeding design capacity (delivery trucks, dumpsters, heavy equipment) compact soil beyond its stable limit.
Nearby Construction
Vibration from nearby excavation or construction compacts soil and can undermine existing concrete.
Repair Options Compared
Each method has tradeoffs—we recommend based on your specific situation
Mudjacking
$3-6/sq ftDrill holes in slab, pump cement slurry underneath to lift concrete to level
Lower cost, fills large voids, proven technique
Heavy material can cause re-settling, visible patch holes, 24-48hr cure
Foam Injection
$5-10/sq ftInject expanding polyurethane foam through small holes to lift slab
Lightweight, quick cure (15 min), smaller holes, waterproof
Higher cost, less effective for large voids, requires stable slab
Slab Replacement
$8-15/sq ftRemove settled concrete, re-excavate, compact proper base, pour new concrete
Addresses root cause, new reinforced concrete, proper drainage grade
Highest cost, longer timeline, requires curing time
