How Foundation Repair Works

Foundation repair is not a single process — it's a family of techniques matched to specific problems. The right repair depends on the type of foundation, the nature of the damage, the soil conditions, and whether the goal is stabilization, lifting, or both. This guide explains the main methods used in Macon and Middle Georgia homes.

Step 1: Inspection and Diagnosis

Every foundation repair job starts with a thorough inspection — free for Macon-area homeowners. We examine exterior walls, interior crack patterns, floors, doors, windows, and the crawl space or basement. We measure crack widths, document locations, check for moisture, and evaluate the soil drainage around the home.

The goal of the inspection is diagnosis: understanding not just that a problem exists, but why it exists. A crack from clay shrinkage settlement needs a different repair than a crack from lateral water pressure. Getting the diagnosis right is how we avoid prescribing solutions that don't match the problem.

Step 2: Selecting the Right Repair Method

For Settlement (Foundation Dropping)

Steel push piers are installed beside the foundation, driven to stable bearing soil below the active clay zone, and used to lift the foundation back toward original grade. The piers are load-tested during installation. This is the most permanent solution for settled foundations.

Polyurethane foam injection fills voids beneath a settled slab and lifts it with expanding foam. Faster and less expensive than piering for moderate settlement with intact soil structure.

For Cracked Walls (No Significant Movement)

Epoxy injection bonds cracked concrete back together under pressure. For dry cracks that have stopped moving.

Polyurethane foam injection seals wet or actively leaking cracks with flexible, waterproof foam.

For Bowing Walls (Lateral Pressure)

Carbon fiber straps stop inward movement permanently without excavation — the preferred solution for walls with less than 2 inches of deflection.

Wall anchors connect the bowing wall to stable soil away from the house via steel rods. Can be gradually tightened to straighten the wall over time.

For Crawl Space Problems

Pier shimming or replacement addresses settled or failed crawl space piers.

Joist sistering strengthens deteriorated floor joists.

Crawl space encapsulation eliminates the moisture causing ongoing structural deterioration.

Step 3: Permits

Structural foundation repairs in Macon-Bibb County require permits from Macon-Bibb County Development Services. We handle all permit applications. Permit documentation protects you at resale and verifies the work was inspected.

Step 4: The Repair

Most repairs are completed in 1–4 days. Crew size, equipment access, and interior disruption vary by method. Push pier installation requires excavation at the foundation perimeter — typically 2-foot square holes at each pier location. Interior repairs (carbon fiber, foam injection, crawl space work) cause minimal disruption to the living space above.

Step 5: Written Warranty

All structural repairs come with a written warranty. The warranty covers the repair method, not general future foundation conditions — if a repaired pier fails, it's covered. If new settlement starts in a different area of the foundation years later, that's a separate evaluation.
