A strong foundation is essential for the stability and safety of any structure. Different foundation types—such as fieldstone, reinforced concrete, and cinder block—can display unique signs of stress under gravity and lateral loads. Recognizing and addressing these signs early is crucial to maintaining a healthy structure.

Common Foundation Issues and Their Causes

Signs of foundation problems include cracks (horizontal, diagonal, vertical, or step-like patterns), bulging or bowing walls, and uneven settlement. Here’s an overview of common crack types and their potential causes:

1. Horizontal Cracks

• Caused by hydrostatic pressure from outside forces such as water-saturated soil pressing against the foundation.

2. Vertical Cracks

• Typically result from differential settlement, which occurs due to:

  • Insufficient footing specifications.

  • Soil with inadequate load-bearing capacity.

  • Long-term water exposure leading to soil instability.

3. Diagonal Cracks

• Often linked to a non-uniform soil profile or prolonged exposure to water, which creates uneven pressure on the foundation.

When to Call a Structural Engineer: If you notice any of these signs, it’s important to have your foundation evaluated by a professional engineer. They can determine the root cause of the issue and recommend the appropriate course of action. Depending on the severity, repairs can range from simple fixes to more complex interventions.

Don’t Ignore Foundation Issues

Your foundation supports your entire home. Addressing problems early can prevent more extensive damage and costly repairs down the line. Protect your structure by consulting an expert at the first sign of trouble.
