How to Repair a Flooded Basement

Flooding is the costliest and most common natural disaster in the U.S. 

Of course, not all flooding is caused by natural disasters. Anything from an uneven foundation to cracks in the wall to a creaky basement window can result in excess water. And even those scenarios that start as a small basement leak can turn into a catastrophe if they aren’t handled correctly. They can lead to property and furniture damage, as well as impact the foundation of your home and result in mold and mildew growth. 

So, how do you handle a flooded basement? As soon as you find your basement covered in water, it’s important to turn off all electricity and gas utilities. Then, check the exterior of your house for signs of deterioration or structural problems to ensure that your basement is safe to enter. Floods can compromise weak structures, and fallen trees or downed power lines can cause further damage. 

Next, you need to ventilate your home to reduce moisture levels (and hopefully minimize mold growth!), as well as remove all wet items from your basement. Instead of attempting to remove all of the water at once, you should pump out a little at a time with a sump pump or a wet vac to reduce the pressure on your walls and the surrounding soil. Once it’s all out, you can dry the area out with fans and a dehumidifier. We explain how to clean walls and remove mold after flooding here. 

If your basement seems to be leaking from the floor, or if the water is coming from somewhere other than the floor, there are several steps you can take to minimize the damage and prevent further problems. We outline different options for how to repair a flooded basement below: 

Helical piers – Foundation walls, cracks, and floor slab leaks are among many possible flood causes. These long, screw-like shafts are drilled into deep soil to repair your foundation and lift it to a level state.  

Encapsulation – This durable, professional-grade crawlspace and basement liner serves as a vapor barrier. It ensures that your basement will stay clean and dry in the future. 

Geo-channel – This system is placed near your foundation footing to direct water away from the floor and wall joints. It is another preventative flooding measure. 

Water tunnel – Used to relieve hydrostatic pressure buildup surrounding your foundation, a water tunnel helps water flow away from your basement (at a rate of 140 gallons per minute!) without putting more pressure on the foundation and walls.  

Mold remediation – This mold treatment is a water-based fungicidal that takes care of and prevents the growth of mold, mildew, fungi, bacteria, and more. Even if you haven’t had to deal with mold yet, we recommend this as a protective coating. 

All of the above steps will help you figure out how to repair a flooded basement. There are also many other ways to prevent water damage moving forward, as discussed in this post about waterproofing your basement.
