How to Waterproof Your Basement Before a Storm
AIM Green Restoration | Columbus, OH
Your basement is one of the most vulnerable areas of your home during storm season. If you’ve ever dealt with flooding in Columbus, you know just how destructive it can be. Here’s how to waterproof your basement before the next storm hits.
Step-by-Step Guide to Basement Waterproofing
- Seal Cracks and Gaps Use hydraulic cement or waterproof caulk to seal visible cracks in walls or floors. Pay close attention to corners, window wells, and pipe entry points.
- Install a Sump Pump A sump pump is your basement’s best defense during a flood. Make sure it’s working, and consider installing a battery backup system in case of power outages.
- Check and Extend Downspouts Downspouts should extend at least 6 feet from your home’s foundation. This prevents rainwater from pooling around your basement walls.
- Improve Drainage Consider installing a French drain or interior drainage system to direct water away from your foundation.
- Apply Waterproof Coatings Waterproof paint or sealant on basement walls adds an extra layer of protection against seepage.
- Test Your Systems Regularly Before storm season begins, test your sump pump, check for any standing water, and make sure your drains are clear.
