How to Stop Water From Getting Into a Storm Cellar

Certain areas of the United States are vulnerable to high-wind storms. It is imperative for residents living in regions such as "Tornado Alley" to have a plan in case a storm hits. This will include a safe-room for the members of the household to converge in. Storm cellars are safe-rooms that sit underground. There is little difference between a storm cellar and the average basement. Waterproofing the room will improve the structural stability and make it more comfortable if you and your family must stay there to wait out a storm.

Instructions

    • 1

      Check during a rain storm to ensure water is running freely out your home's gutter downspouts. Remove any leaves or debris that may be blocking water flow through the gutters.

    • 2

      Replace sealant on any cement areas around the exterior of the cellar if needed. As sealant ages, it may crack or become less effective. Strip the old sealant off the cement surface before you apply new waterproofing. Follow the instructions provided with the product for proper application.

    • 3

      Landscape the outside of your home or around the cellar entrance so the soil slopes downward from the structure. This will force the water to run in the opposite direction of the foundation.

      Fill any cracks in the walls of the cellar with a waterproofing sealant. In most cases, an injector sealant will close the crack and waterproof the area at the same time.
