Understanding Sinking Foundations

What is a Sinking Foundation?

A sinking foundation happens when the ground below a building starts to give way, making the building sink unevenly. This can happen because of several reasons:

• Soil Erosion: Heavy rain can wash away the soil that supports the foundation.
• Poor Compaction: If the soil wasn’t packed down properly during construction, it can settle over time.
• Hydrostatic Pressure: Water pressure can push against the foundation walls, causing them to crack or collapse.
• Shrinking and Expanding Soil: Clay soil can get bigger when wet and smaller when dry, making the ground move.

Common signs of a sinking foundation include:

• Cracks in Walls and Floors: Look for cracks that look like stairs in brick walls or horizontal cracks in the basement.
• Uneven Floors: Floors that slope or bounce are signs of trouble.
• Sticking Doors and Windows: If doors and windows are hard to open or close, it might mean you have foundation issues.

Why Sinking Foundations are a Problem

A sinking foundation is more than just an annoyance:

• Structural Risks: It can make your home unsafe by weakening its structure.
• Property Value: A home with foundation problems loses value and becomes harder to sell.

How to Identify a Sinking Foundation

Visual Clues to Watch For

Be on the lookout for these warning signs:

• Cracks in Basement Walls or Floors: Vertical or diagonal cracks are common.
• Gaps Around Windows and Doors: Changes in frames can show ground movement.
• Sloped Floors: Use a marble or ball to see if it rolls without stopping.

Tools and Tests You Can Use

• Level or Laser Level: Check different points in a room to see if they’re uneven.
• Water Test for Floor Slope: Pour water on the floor and see if it always flows to one corner.

• Problems Don’t Go Away: If the same issues keep coming back, you need an expert.
