What Causes Foundation and Wall Cracks in O’Fallon Homes?
Expanding and Contracting Soil
O’Fallon’s clay-rich soil is known to swell when wet and shrink during dry spells. This constant expansion and contraction creates pressure on your home’s foundation, leading to wall or floor cracks.
Drainage Problems and Water Accumulation
When rainwater or melting snow isn’t properly diverted away from your home, it creates hydrostatic pressure against your basement walls—resulting in bulging, cracking, and eventual water intrusion.
Tree Root Invasion
Mature tree roots near your foundation can absorb soil moisture or physically displace the ground, which weakens foundation support and causes cracking.
Construction Deficiencies or Aging Foundations
Some older or quickly built homes in O’Fallon may lack proper soil preparation or foundational support, making them more susceptible to settling and crack formation over time.
Freeze-Thaw Weather Patterns
Seasonal temperature changes cause materials like concrete and masonry to expand and contract. Over time, this repeated stress can create or widen existing cracks.
Why O’Fallon Homeowners Should Repair Wall and Foundation Cracks Promptly
Prevent Costly Structural Failures
Ignoring minor cracks can lead to major foundational shifts and costly repairs. Early intervention helps keep the damage manageable.
Protect Against Water Damage and Mold
Cracks allow groundwater to seep into your basement, causing damp conditions, mold growth, and long-term moisture damage to finishes and belongings.
Safeguard Indoor Air Quality
Moisture infiltration increases the risk of mold and mildew, which can trigger asthma and other respiratory issues—especially in enclosed basement spaces.
Maintain Home Value and Marketability
A cracked or unstable foundation can significantly reduce your property’s resale value. Repairing it now helps preserve equity and appeal.
Our Trusted Foundation Crack Repair Process in O’Fallon, Missouri
Step 1: Foundation and Wall Assessment
We conduct a thorough evaluation of your foundation, wall structure, and surrounding soil to identify the root cause of cracks and determine the appropriate fix.
Step 2: Sealing with Epoxy or Polyurethane
Smaller or non-structural cracks are sealed using high-quality epoxy or flexible polyurethane injections to prevent further cracking and moisture entry.
Step 3: Foundation Stabilization with Piering
If settlement is an issue, we install steel push piers or helical piers deep into stable soil layers to lift and permanently stabilize your foundation.
Step 4: Wall Reinforcement
For walls that are bowing or shifting inward, we use carbon fiber reinforcement or steel bracing systems to support and straighten the structure.
Step 5: Waterproofing and Drainage Upgrades
To protect against recurring moisture, we install interior/exterior drainage systems, sump pumps, and waterproof membranes designed for O’Fallon’s soil and climate.
Step 6: Slabjacking for Concrete Repair
We raise sunken slabs like basement floors or driveways using slabjacking. This involves injecting a dense grout mixture underneath to restore level support.
