If your basement has been flooded, it is important to contact your local health department for information on how to clean your basement concrete floor. Water damage can cause health hazards such as mold, mildew, and bacteria. The health department can provide you with the necessary steps to take to clean your floor and prevent further damage.
If there is any mold or mildew on the floor, you should remove it before cleaning the rest of the floor. To remove mold or mildew, you can use a mixture of bleach and water. Be sure to wear gloves and a mask when working with bleach.
Once the floor is clean and dry, you should inspect it for any damage. If there is any damage, such as cracks or holes, you should repair it before using the floor again.
