Basement flooding is a common issue for homeowners in Nebraska and Iowa. Whether it’s from heavy rain, rapid snowmelt, or poor drainage around the foundation, water can quickly find its way into your home. If you’ve dealt with a flooded basement before or want to prevent it from ever happening, this guide covers what you need to know.
Common Causes of Basement Flooding
1. Heavy Rainfall
Spring and summer storms can drop several inches of rain in a short time. If the ground is already saturated, water has nowhere to go and may seep through cracks in your foundation walls or basement floor.
2. Melting Snow and Thawing Ground
When snow melts rapidly in late winter or early spring, especially if combined with spring rain, the ground can’t absorb all the water. Thawing soil also releases moisture, adding to the saturation and hydrostatic pressure against your foundation.
3. Clogged or Broken Gutters and Downspouts
Gutters and downspouts are your first line of defense against water pooling around your foundation. If they’re clogged, broken, or too short, water can flow directly down to the base of your home.
4. Poor Drainage Grading
If the ground around your home slopes toward the foundation instead of away, water will naturally collect along your basement walls. This often leads to leaks and long-term foundation issues.
5. Cracks in Foundation Walls or Floors
Even tiny cracks in your foundation can allow water to seep through. Over time, water pressure can widen these cracks, increasing the chances of serious flooding.
6. Failing or Absent Waterproofing Systems
Older homes may lack modern waterproofing solutions like sump pumps, drain tile, or vapor barriers. Without these systems, your basement is more vulnerable to water intrusion.
What to Do if Your Basement Floods
1. Stay Safe
Before entering a flooded basement, make sure the electricity is off. Water and electricity are a dangerous mix. If in doubt, call a professional.
2. Remove the Water
Use a sump pump, wet/dry vacuum, or even buckets to start removing water. The faster you get the water out, the less damage you’ll have to deal with.
3. Dry Everything Out
Fans, dehumidifiers, and ventilation are key to drying out your basement. Remove soaked items like carpet, insulation, and cardboard boxes, as these can harbor mold.
4. Clean and Disinfect
Even if the water seems clean, bacteria and mold can form quickly. Scrub walls and floors with disinfectant to avoid health issues.
5. Document the Damage
Take photos of all the damage and make a list of affected items for insurance purposes. If you have flood insurance, contact your agent right away.
How to Prevent Basement Flooding
Check Gutters and Downspouts
Make sure gutters are clean and downspouts extend at least 10 feet away from your foundation. You should have one downspout for every 600-800 square feet of roof surface.
Inspect the Slope Around Your Home
The soil should slope away from your foundation by at least six inches over the first four feet. Fill in any low spots and consider regrading problem areas.
Seal Foundation Cracks
Small cracks can be patched with waterproof sealant, but larger or persistent issues should be addressed by a foundation repair expert.
Install or Upgrade Your Waterproofing System
A comprehensive waterproofing system may include:
- Interior drainage channels
- Sump pump with battery backup
- Vapor barriers
- Exterior drainage and membrane systems
Test Your Sump Pump Regularly
Pour water into the sump pit to make sure the pump turns on and drains properly. If it doesn’t work, get it repaired or replaced before the next storm.
Clear Snow Away from Foundation Walls
In the winter, shovel snow away from the perimeter of your home. This prevents early thaw water from running straight down into your foundation.
