Can Rainwater Damage Your House Foundation?

in Portland OR and Vancouver WA areas

Living in the Pacific Northwest, rain is practically a part of daily life, and while it’s essential for our lush landscapes, it can cause damage and wear and tear to our homes in several ways. One frequently overlooked aspect of this is foundation damage. Yes, rainwater can damage your house foundation, particularly in regions like ours. 

Here at Masonry Waterproofing, and Drainage Masters, we’ve seen it on numerous occasions. While it’s not common, any type of foundation damage can be a major issue, so it’s worth understanding the risks. Here’s what you need to know.

How Does Rainwater Damage a House Foundation?

Rainwater can damage your home’s foundation in two primary ways: through hydrostatic pressure and erosion. Understanding how these forces work can help you take the necessary steps to prevent damage and avoid foundation repair.

Hydrostatic Pressure

Imagine the soil surrounding your home as a sponge. During heavy rainfall, this “sponge” becomes saturated with water, creating pressure against your foundation walls. This pressure, known as hydrostatic pressure, can lead to cracks and leaks in your foundation. Over time, this can compromise the structural integrity of your home, leading to costly repairs.

Erosion

As rainwater flows over and around your property, it can carry away soil particles, slowly undermining the foundation. This process is gradual but relentless, leading to uneven settling, cracks, and even structural shifts in your home.

Prevent Rainwater Foundation Damage with an Underground Drainage System

Yes, rainwater can damage your house foundation, but we offer an excellent solution. An underground drainage system channels rainwater runoff far enough away from your foundation that you don’t have to worry. Your underground drainage system is custom-designed for your property and protects your investment in your home in several ways:

• Redirects water away: By channeling rainwater away from your home, this system reduces hydrostatic pressure and minimizes erosion around the foundation.
• Reduces humidity levels: Drier ground means less humidity around the foundation, decreasing the likelihood of damp-related issues inside your home.
• Prevents structural damage: Consistently directing water away preserves the structural integrity of your foundation, potentially saving you from expensive future repairs.
• Protects landscaping: An underground drainage system preserves your landscaping by preventing waterlogging and erosion.

Signs of Rainwater Foundation Damage

Do you know the early warning signs of rainwater foundation damage? Learn to recognize them so you can address the issue before it gets worse.

• Cracks in the foundation: Vertical, horizontal, or stair-step cracks can all indicate pressure and settling issues.
• Water in the basement: dampness, puddles, or actual flooding are red flags.
• Doors and windows sticking: Shifts in your foundation can cause frames to warp, leading to sticking or misalignment.
• Uneven floors: If your floors feel bouncy or slanted, this might be a sign of foundation settling.
• Mold and mildew: High humidity and water intrusion create the perfect environment for mold growth.
