Interior Basement Floor Unevenness

Basement concrete floors can develop uneven sections, cracks, or depressions when the soil beneath them loses density through moisture changes, organic decay, or poor compaction during original construction. These unlevel surfaces make finishing the basement difficult, create tripping hazards, and often indicate active void formation. Polyurethane foam injection lifts and re-levels the affected panels from below, filling voids and restoring a flat, stable surface without demolition.
