June 23, 2025

Understanding the Root Causes of Foundation Cracks

Foundation cracks are a common concern for homeowners throughout Arkansas and Missouri. Whether you notice a thin hairline fracture in your basement wall or a jagged gap along your home’s exterior, one thing’s for sure—foundation cracks should never be ignored. At Haven Contracting, we’ve repaired hundreds of foundations across Southside, West Plains, Batesville, and beyond. In this blog post, we’ll walk you through the types of foundation cracks, what causes them, and when it’s time to call a professional.

Why Foundations Crack in the First Place

Several environmental and structural factors contribute to foundation cracking, especially in regions like Independence County, AR, and southern Missouri, where clay soils, extreme weather, and heavy rainfall are common.


Common causes include:

  • Soil settlement or expansion due to moisture fluctuations
  • Hydrostatic pressure from poor drainage or waterlogged soil
  • Improper construction or undersized footings
  • Tree roots expanding underneath or near the foundation
  • Freeze-thaw cycles that expand small cracks over time

5 Types of Foundation Cracks & What They Mean

Not all cracks are created equal. Here’s a breakdown of the most common types and what each one could indicate:

  • Hairline Cracks

    What they are: Very thin, surface-level cracks in concrete.


    What they mean: Typically caused by shrinkage during curing.


    Should you worry? Not usually—but monitor to ensure they don’t widen.

  • Vertical Cracks

    What they are: Cracks that run straight up and down.


    What they mean: Often due to normal settling or minor foundation movement.


    Should you worry? Mild concern; may require sealing to prevent water entry.


  • Horizontal Cracks

    What they are: Cracks that run parallel to the ground.


    What they mean: Can signal serious structural pressure, often caused by hydrostatic soil pressure.


    Should you worry? Yes. These need immediate inspection and reinforcement.

  • Stair-Step Cracks in Brick or Block

    What they are: Cracks that follow mortar joints in a zigzag pattern.


    What they mean: Usually a sign of foundation settlement or movement.


    Should you worry? Yes, especially if they widen or are accompanied by bowing walls.

  • Diagonal Cracks

    What they are: Angled cracks, often at windows or door frames.


    What they mean: May result from differential settlement—one part of your foundation settling faster than another.


    Should you worry? Monitor closely; if doors stick or gaps widen, call in an expert.
