Knowing About Foundation Walls

What Are Foundation Walls?

What They Do: Foundation walls hold up your home. They spread the weight of the house to the ground, keeping everything stable and strong.

Types of Foundation Walls:

• Poured Concrete: These are very strong and last a long time.
• Masonry: Made of stone or brick, usually found in older houses.
• Block: Made of concrete blocks, common in many homes.

Why Foundation Walls Matter

Holding Up the House: They support the house and keep it standing.
Keeping Water Out: They stop groundwater from coming into your basement.
Keeping It Warm: They help keep your basement warm by providing insulation.

Common Problems with Foundation Walls

Cracks in the Wall

Types of Cracks:

• Vertical Cracks: Caused by the foundation settling.
• Horizontal Cracks: Could mean serious structural problems due to outside pressure.
• Diagonal Cracks: Often from uneven settling of the foundation.

Why Cracks Happen:

• Soil Settling: When soil moves, it can shift the foundation and cause cracks.
• Water Damage: Too much moisture can weaken the walls and cause cracks.
• Bad Building: Using low-quality materials or bad techniques can create cracks.

Bowing Walls

What It Looks Like: The wall curves or bulges inward.
Why It Happens: Too much water pressure in the soil can push the wall inward.

Water Leaks

Where It Comes From:

• Groundwater: High levels of water can seep into your foundation.
• Rainwater: Bad drainage can let rainwater leak into your basement.

Signs of Leaks:

• Damp Spots: Wet areas on your walls.
• Mold: Mold growing due to constant moisture.
