Wisconsin might not sit in tornado alley or a hurricane zone, but it’s no stranger to severe weather, especially heavy rain events. And if you’ve lived in Wisconsin long enough, you’ve either dealt with a flooded basement or know someone who has. The effects of a flooded basement can be devastating, ranging from the loss of valuable and sentimental family heirlooms to a collapsed foundation.
Although you can’t control the weather, you can control the likelihood of experiencing basement flooding.
Understanding the causes of basement flooding
Surface water runoff is a frequent culprit, occurring when rainwater or melting snow gathers around your home’s foundation. Heavy rainfall and rapid snowmelt amplify these issues, especially in areas prone to sudden weather changes (like Wisconsin).
Poor drainage is another significant factor — water that pools too close to the house can lead to water intrusion.
Foundation cracks are also gateways to basement flooding, often a result of the two causes explained above.
Strategies outside the basement
Preventing basement flooding starts with the exterior of your home:
- Gutter and downspout maintenance: Make sure gutters and downspouts are clear of debris to allow rainwater to flow freely. Downspouts should direct water at least six feet away from your home’s foundation. These simple steps will significantly reduce the risk of water pooling near your basement walls.
- Good grading: Proper grading around your home is equally important. The ground should slope away from your foundation to encourage water runoff, ideally dropping at least six inches over the first ten feet. If you notice areas where water collects, adding soil to create a better slope will help keep your basement dry during those spring and summer thunderstorms.
- Effective landscaping: Plant trees, shrubs, and other perennials — they will gladly drink up excess moisture on your behalf. You could also install a rain garden or use permeable paving in the walkways around your home.
Strategies inside the basement
Taking care of your basement’s interior is just as important as your home’s exterior:
- Install a sump pump: A sump pump collects and removes excess water that may accumulate in your basement. Regular maintenance, like checking for blockages and testing the pump periodically, will give you confidence it will kick in when needed.
- Install a drainage system: These systems, like French drains, direct water away from areas prone to flooding, channeling it to a sump pump or drainage outlet. You’ll want to keep these systems clear of debris and inspect them regularly.
- Waterproof your basement walls and floors: Applying waterproof sealants and coatings creates a barrier against moisture intrusion. Adding vapor barriers to walls and floors can help keep water from seeping in even more.
Emergency preparedness for heavy rain events
Start by creating an emergency plan that includes a clear communication plan with your family. Figure out the safe areas in your home and establish a point of contact outside your immediate location. Make sure everyone knows how to respond quickly, including evacuation routes, should flooding occur.
It’s also smart to have the right tools and materials on hand in preparation for a heavy rain event. Stock up on sandbags to help divert water away from your home. Keep a flashlight, extra batteries, and a first aid kit nearby. Lastly, use waterproof storage bins for important documents and valuables to protect them from potential water damage.
Know when to call a professional for help. If you notice signs of water seepage before heavy rains, like foundation cracks or persistent dampness, hire a local contractor who specializes in waterproofing. If your basement floods and you’re unsure how to clean and restore the area, restoration experts can help you.
Flood coverage is typically not included in standard homeowner’s policies, but many insurance companies, including Rural Mutual, offer additional coverage options for qualified policyholders. Talk to a local Rural Mutual agent to see if you qualify for coverage alternatives that can help keep your head above water should flooding occur.
