What Are the Types of Foundational Cracks?

The direction of a foundation crack reveals key information about its cause and severity. Vertical cracks, which run up and down or diagonally, typically occur in poured concrete foundations due to natural settling or shrinkage and often appear within a few years of construction. While they may seem minor, water intrusion or widening can signal the need for repair. Horizontal cracks, running side to side, are more serious. They often result from soil or water pressure against the foundation and may indicate structural failure. Regularly check cracks for changes in size or direction, and document them with photos.

Common Causes and Risks of Foundational Cracks

Foundation cracks can form for several reasons, and knowing the cause helps determine the right solution. Whether vertical or horizontal, you should never ignore these cracks, as they can lead to severe damage over time. Here’s what causes vertical and horizontal cracks in foundations:

Causes of Vertical Cracks:

Natural settling of the foundation can create small vertical cracks, especially in newer homes. These are often harmless but allow water to seep in without treatment.
Shrinkage during concrete curing may lead to narrow cracks as the material dries. These cracks are common, but we recommend monitoring them for growth.
Minor soil shifts beneath the foundation can stress the concrete. This change can cause thin vertical cracks in the foundation that expand with time.
Temperature changes can cause expansion and contraction. Over time, this movement may lead to cracking in the foundation.

Causes of Horizontal Cracks:

Soil or hydrostatic pressure pushes against foundation walls. This condition can result in bowing and dangerous horizontal cracks in the foundation.
Poor drainage or overflowing gutters allow water to collect near the foundation. Moisture buildup weakens the wall structure.
Freezing and thawing cycles create expanding pressure in the soil. This cycle repeats seasonally and adds stress to the walls.
Improper backfilling during construction can leave uneven pressure on foundation walls. This situation increases the risk of cracking under load.

Risks of Ignoring Cracks:

Water seepage can lead to basement dampness and mold growth. Over time, this condition can affect your indoor air quality.
Cracked or weakened concrete may compromise the structural strength of your home. This situation often leads to more extensive damage.
Bowing or bulging walls indicate pressure has gone unchecked. This condition requires immediate professional repair.
Delaying repairs can increase long-term costs. Early intervention helps you avoid full wall replacements.

How to Prevent Foundation Cracks and Costly Repairs

Preventing foundation cracks starts with controlling moisture around your home. Water is one of the leading causes of vertical and horizontal cracks, so taking simple steps now can save you from costly repairs later. Waterproofing for foundation crack prevention protects your property and avoids costly repairs. Here’s how to prevent foundation cracks from affecting your home:

Maintain Proper Grading—Ensure the ground slopes away from your foundation. This step helps prevent rainwater from pooling near the base of your home.
Install and Clean Gutters and Downspouts—Directing water away from your foundation protects it from constant moisture. Clean gutters regularly to prevent overflow and clogs.
Use Sump Pumps—A sump pump removes water from your basement before it builds up. This equipment reduces the risk of pressure on your foundation walls.
Repair Plumbing Leaks Immediately—Even small leaks can lead to water accumulation around your foundation. Quick repairs can prevent long-term damage.
Schedule Regular Inspections—A yearly inspection helps catch early signs of damage or moisture problems. This proactive step extends the life of your foundation.
