What To Do During Flash Flooding and How to Prevent It
Recently, Owatonna, MN, and surrounding areas have been hit with intense flash flooding, leaving many homeowners in stressful and unexpected situations. When you partner with American Waterworks, you gain peace of mind knowing your home is protected and in the right hands for years to come.
What is Flash Flooding
Flash flooding is the rapid rise of water along streams, rivers, or low-lying urban areas caused by intense storms that produce heavy rainfalls in a short amount of time (NASA, 2026). While heavy rain is the most common cause, flash floods can also result from dam or levee failures, mudslides, or debris flow.
What makes flash flooding especially dangerous is how quickly it develops, often within just a few hours of a major rain event. Because it happens so fast, it can easily catch people off guard. High, fast-moving water can pose serious risks, especially for those traveling during a storm.
Flash flooding can occur anywhere, but urban areas are particularly vulnerable due to rapid runoff (US, 2024). However, rural and suburban areas, like Owatonna and surrounding communities, can experience more severe impacts due to soil saturation and drainage challenges.
How Can It Affect Your Home?
Basement Flooding:
One of the most common signs of flash flood damage is a wet basement. If your home has been affected, you may notice:
- Damp Walls
- Wet Floors
- Efflorescence
- Mold Growth
- Standing Water
- Sagging Floors
- Rotting Walls
Foundation Repair:
Flash flooding can also put your home's foundation at risk due to hydrostatic pressure, the force exerted by water as it builds up in the soil and around your home. This pressure can push against foundation walls and lead to structural issues over time.
Foundation damage signs include:
- Cracked Foundation
- Sagging Floors
- Shearing Walls
- Sticking Doors + Windows
- Bowing Walls
How American Waterworks Can Help You Stay Prepared
Preparation is key when it comes to protecting your home from flash flooding. If you notice water leaking into your basement in Owatonna, MN, here are a few ways you can stay ahead of the storm:
#1. Keep Gutter Clear
Make sure your gutters and downspouts are free of leaves, dirt, and debris. Clear gutters allow water to flow away from your home instead of pooling around the foundation.
You can take proactive steps before a storm ever hits. American Waterworks offer award-winnig waterproofing systems designed to keep your basement dry and secure.
- WaterGuard System: A perimeter drainage system that captures water at the basement edge and directs it safely away from your home
- CleanSpace Vapor Barrier: A durable wall system that prevents water vapor intrusion while directing any leaks to the drainage system
- TripleSafe Sump Pump: A highly reliable system with three pumps, designed to handle heavy water flow, even during power outages
Even small cracks or slight movement can be early warning signs of foundation damage. Addressing these issues early can prevent more serious problems later.
American Waterworks offers several proven solutions:
- GeoLock Wall Anchors: A permanent system designed to stabilize bowing or shifting walls
- PowerBrace System: An interior solution that stabilizes and can gradually straighten walls over time
- CarbonArmor: A fiber-reinforced solution that is stronger than steel while remaining flexible enough to reinforce foundation walls effectively
#4. Maintain Your System
Ongoing maintenance helps ensure your waterproofing and foundation systems continue to perform at their best.
American Waterworks offers a dedicated Service Team that will:
- Reduce emergency repair needs
