Mudjacking Lifts Sunken Slabs With Pressure-Pumped Cementitious Slurry.

Mudjacking runs $3 to $6 per square foot of slab lifted in our region. Typically the least expensive lift method by material cost. A typical sunken driveway section (200 to 400 square feet) commonly falls between $900 and $2,400. Material cost scales linearly with void volume, so large void fills are where mudjacking's pricing advantage over polyurethane foam shows up most clearly. Written estimate after on-site inspection reflects your scope.

Once cured, cementitious slurry is a permanent fill material. The cement hardens and forms a stable load-bearing column. Epp Foundation Repair backs the installation with a 3-year written warranty against re-settlement at the treated area. The warranty is shorter than the 5-year foam warranty because slurry's higher weight slightly increases the chance of secondary soil consolidation under the cured fill. Warranty stays with the home.

The void underneath enlarges over time. Soil continues to wash, consolidate, or shrink, and the slab continues to drop. The tripping edge gets steeper, drainage runs the wrong direction, and adjacent slab sections start cracking from the lateral pull. A $1,500 mudjack today is materially cheaper than a $5,000 replacement two years from now once the slab has cracked beyond a lift candidate. The longer the wait, the more often the answer shifts from lift to replace.

Foam wins on most residential driveways and sidewalks: cleaner injection (5/8-inch ports vs. 1 to 2-inch holes), faster cure (15 minutes vs. 24 to 48 hours), lighter load (4 lb/cu ft vs. 100 lb/cu ft), and a longer 5-year warranty. Mudjacking wins on very large void fills where material cost dominates, on jobs where slab weight isn't a soil concern, and on budget-sensitive scopes where the lower per-square-foot cost makes a difference. Dave Epp's crews quote both methods on every applicable estimate so the homeowner can choose.

Properly mixed slurry cures into a solid cementitious column. At that point it's no longer a slurry, it's effectively a thin concrete pad bonded to the underside of the slab. Settlement that does occur after a cured mudjack almost always traces back to the underlying soil failure that was never addressed: a downspout still dumping at the foundation, irrigation still saturating the same zone, or grading still pitched the wrong way. The slurry doesn't fail. The soil does. That's why every mudjacking inspection includes a check for the water source.

The patched holes are visible up close. They're roughly the diameter of a quarter and patched with concrete grout. On a finished driveway or sidewalk, they read as small repair spots, not as a major visual scar. Polyurethane foam ports (5/8-inch) are less visible by a meaningful margin because they're smaller. For homeowners where visual appearance is a priority. A stamped concrete patio, a colored driveway, a decorative pool deck. Foam injection is usually the recommended method even when budget would favor mudjacking.
