What Are Basement Floor Cracks?

Why Do They Happen?

• Soil Moves: The ground under your basement can shift and cause cracks.
• Water Pressure: Water in the soil can push into your basement and make cracks.
• Concrete Shrinks: When concrete dries, it can shrink and create small cracks.

Types of Cracks and What They Mean

• Tiny Cracks: Usually not a big deal but can be an early warning.
• Big Cracks: These are wide and can be serious, so fix them fast.
• Settlement Cracks: These happen when your house settles over time and are usually even.
