Concrete Pouring: Replacing Failed Slabs With Properly Prepared, New Concrete

Lifting methods like mud jacking and polyurethane foam injection are made for slabs that are structurally sound but have settled and become uneven. Pouring new concrete is the better answer when a slab is too cracked, spalled, crumbling, or deteriorated to lift and reuse, because raising broken pieces does not give you a sound surface. During your no-pressure inspection we look at the actual condition of the slab and tell you honestly which approach fits. In many cases a slab can be lifted rather than replaced, which is faster and more cost-conscious.

A new slab is only as stable as the base beneath it. In the Carolinas, most slab failures trace back to the soil, not the concrete. Active Piedmont clay swells and shrinks with the seasons, Sandhills sand lets fines wash out, mountain runoff undermines sloped lots, and coastal areas near Wilmington and Brunswick County stay saturated. If we pour fresh concrete over that same unaddressed ground, it tends to fail again. That is why we correct and compact the base, and address drainage where needed, before any new concrete goes down.

Concrete continues to gain strength for weeks after it is placed, but you do not have to wait that long to use it. As a general guide, a new slab is usually ready for foot traffic within a day or two and can typically carry vehicle weight after about a week, though the exact timing depends on the slab, the mix, and Carolina weather conditions like summer heat or a sudden rain. We manage the cure and tell you exactly when your specific slab is ready for foot traffic and for vehicles.

Not by itself. A new pour gives you a sound slab, but it does not change deeper soil behavior or drainage problems that caused the original concrete to fail. If the cause is something like water draining against the slab or unstable subgrade, we address that as part of the recommendation, sometimes with grading or drainage corrections and sometimes with base preparation, so the new slab is far more likely to hold. Pouring over an unaddressed cause is how a replacement slab ends up cracking the same way the old one did.

Cost depends on the size and thickness of the slab, removal and disposal of the old concrete, how much base preparation and compaction the ground needs, reinforcement, access to the area, the soil conditions, and whether any drainage correction is recommended alongside the pour. Because those factors vary from one project to the next, we provide pricing after a no-pressure inspection rather than a flat number online. The inspection is how we give you an accurate, honest estimate for your specific situation.
