Is Your Columbia, SC Slab Foundation Shifting?

What is Slab Foundation Shifting? 

Slab foundation shifting occurs when the concrete slab of a home or building settles unevenly due to soil and moisture changes or other factors. This shifting can cause foundation cracks and other structural damage.

In Columbia, SC, including neighborhoods like Forest Acres, slab foundations are prevalent due to their cost-effectiveness. However, the area’s clay-rich soil contracts when it becomes dry and expands when it’s wet, making home foundations more susceptible to shifting over time.

Recognizing the warning signs of slab foundation damage can help you address issues before they worsen.

What Causes Slab Foundation Problems in Columbia, SC?

When you recognize signs of damage, you may wonder what caused it. Several local factors contribute to slab foundation shifting in Columbia, SC, including:

• Expansive Clay Soil: Many areas in Columbia, including Lexington and Richland counties, have clay-heavy soils that expand when wet and shrink when dry, creating foundation instability.
• Climate: Hot, humid summers and annual rainfall cause soil fluctuations, creating voids that lead to slab foundation shifting.
• Floodplains and Water Table Fluctuations: Homes near the Congaree River or in low-lying flood-prone areas may experience more dramatic soil movement due to fluctuating water levels.
• New Construction and Soil Disturbance: Developing communities like Northeast Columbia and Blythewood often have homes built on recently disturbed or improperly compacted soil, which may settle unevenly over time.
• Tree Roots: Tree roots exert pressure on foundations as they grow, often causing slab issues.
• Plumbing Issues and Water Leaks: Leaky pipes, especially under or near the slab foundation, can cause localized soil swelling or erosion, leading to foundation problems. 
• Improper Drainage: Clogged gutters and downspouts and improper grading and drainage systems can cause water pooling and soil saturation, which causes slab foundation settling.
• Construction Defects: In some cases, slab foundation problems stem from errors in the original construction, such as inadequate soil compaction, improper concrete mix, or insufficient curing.

Monitor any signs of slab foundation damage, as unaddressed issues can lead to safety risks, structural instability, higher repair costs, and decreased home value.

Professional vs. DIY Slab Foundation Repair: What to Know

You may wonder whether DIY slab foundation repair is even an option. While small concrete cracks can sometimes be patched, significant foundation settlement requires professional repair for a long-term result. Common professional foundation repair options in Columbia, include:

• Professional Inspections: Identify and diagnose the damage.
• Soil Stabilization: Helps prevent further slab foundation shifting.
• Foundation Piering Methods: Reinforce and stabilize the slab foundation.

What is the Best Way to Repair a Slab Foundation?

Foundation repair experts in Columbia, SC, may recommend the following repair methods based on the extent of damage:

• Concrete Lifting (polyurethane foam injection): This method stabilizes the soil and lifts and levels uneven slabs.
• Concrete Slab Piers: These piers stabilize the slab by transferring the structure’s weight to stable soil, potentially lifting the foundation to its original position.

Professionals may also use helical piers and push piers, depending on the location and extent of the foundation damage.
