Frequently Asked Questions
Common questions about slab foundation repair in Ontario, CA.
Slab Foundation Repair Ontario, CA
Why Ontario Slab Foundations Suffer Differential Settlement
The Inland Empire is characterized by heavy alluvial deposits and highly expansive clay soils that undergo drastic volumetric changes between prolonged summer heat waves and winter storm deluges. When soil loses moisture during dry spells, it shrinks and retreats away from concrete footings, leaving foundation sections unsupported. When heavy rains return, uneven soil swelling creates differential heave. This uneven movement exceeds the concrete's tensile strength, resulting in cracked floor slabs, misaligned door frames, and outward-leaning exterior walls. Professional underpinning stabilizes the footprint independently of surface soil fluctuations.
