Why Slabs Crack and Settle in Macon
Slab foundations are common throughout Macon, Bibb County, and surrounding areas. But they are particularly vulnerable to Georgia's expansive red clay soil. As clay absorbs water and swells in wet months, then dries and contracts in summer, the slab is subjected to uneven upward and downward forces. Over time this creates cracks, voids beneath the slab, and sections that settle or heave unevenly.
Slab foundations in Macon and Bibb County are vulnerable to Georgia's expansive red clay soil, which swells in wet months and contracts in summer, creating cracks, voids, and uneven settling — plumbing leaks beneath the slab are another common cause. Macon Foundation Repair Co repairs slabs with slabjacking, polyurethane foam injection, pier underpinning, or epoxy crack sealing depending on severity.
Plumbing leaks beneath slab foundations are another major cause of slab damage in Macon — erosion from a leaking pipe washes away supporting soil and creates voids that allow sections of the slab to drop.
Our Slab Repair Methods
- Slabjacking (mudjacking) — a slurry mixture is pumped beneath the settled slab through small drilled holes, filling voids and lifting the slab back to grade.
- Polyurethane foam injection — a faster, lighter-weight alternative. Expanding foam fills voids and lifts the slab with minimal disruption.
- Pier underpinning — for slabs with significant structural settling, push piers driven to bedrock provide permanent stabilization and controlled lifting.
- Crack repair — surface cracks are sealed with epoxy or polyurethane to prevent water infiltration.

- Doors that stick or won't latch
- Tile floors with cracks running across multiple tiles
- Separation between floor and baseboards
- Gaps appearing between walls and ceiling
