4 Mudjacking Contractors in Longs, SC

Heavy seasonal rainfall can drop several inches in a single week, and that volume of water finds its way under every slab that doesn't have proper drainage. Clay-rich soils are common across much of the region. They expand when wet and shrink when dry, and that movement pushes slabs out of alignment. Driveway slabs settle near the garage transition, where runoff gathers and gradually erodes the soil underneath. Mudjacking works for heavier slabs like stoops and garage floors, though foam injection is gaining ground for jobs where moisture is the root cause.

Polyurethane foam injection is the most widely used concrete leveling method in the Longs and greater Horry County area. Contractors drill small holes into the settled slab and inject lightweight expanding foam that fills voids beneath the surface and lifts the concrete back to its original grade. The foam cures quickly, resists water absorption, and performs well in the high-moisture environment found across the coastal plain. Mudjacking with a cement slurry is also available and typically costs less, though the heavier material can add stress to already soft, sandy soils. Foam leveling in the Longs area generally runs $5 to $10 per square foot, while mudjacking averages $3 to $6 per square foot. Most residential projects fall between $500 and $2,000, with the average job landing around $800 to $1,400. Small repairs like a single sidewalk panel or front stoop may cost under $600, and larger driveway or pool deck work can reach $2,500 to $4,500. Leveling typically saves 50% or more compared to full slab demolition and replacement, which runs $6 to $10 per square foot for new concrete in the Horry County market.

Concrete leveling can be done year-round in Longs thanks to the mild subtropical climate. Spring and fall are the most popular scheduling windows, with moderate temperatures and less frequent heavy rain. Completing work before hurricane season begins in June is a smart strategy, ensuring slabs are level and draining properly before the wettest months of the year.

Mudjacking (also called slabjacking) is a technique that lifts sunken concrete by pumping a cement-based slurry beneath the slab through small drilled holes. It is a cost-effective alternative to full slab replacement. Most residential projects wrap up in a few hours, making it a practical alternative to full slab replacement.

High rainfall and clay-heavy soils make the Southeast prone to washout beneath concrete slabs. Settlement issues often appear after prolonged rainy seasons when saturated soil compresses under the slab's weight. In Longs, many homeowners schedule inspections before peak season to get faster turnaround times. South Carolina sits in the southeast region, so weather patterns can influence project timing.

Most concrete settlement in Longs traces back to the soil underneath. When fill dirt wasn't compacted properly during construction, or when water from rain, irrigation, or plumbing leaks erodes the subgrade, voids form beneath the slab. Those voids let the concrete drop. In parts of South Carolina, expansive soils make this cycle especially common because they shift with changes in moisture.

The sooner you address settled concrete, the simpler the fix. Longs contractors can typically level a residential slab in a single appointment, often in under half a day.
