How Do You Clean Flooded Concrete Floor?
The porous nature of concrete floors allows for the absorption of materials into the floor. This makes it particularly tricky to clean concrete floors after a flood. Water causes stains and the formation of mold and mildew which results in dank, musky odor. If another substance, such as oil or gasoline, gets mixed into the flood water, these materials get absorbed into the concrete as well. Staining or sealing concrete prevents the absorption of these materials and allows for quicker clean-up. However, unsealed concrete floors can be cleaned and restored with a little bit of work. Wait for the flood water to recede or rent a sump pump to speed up the process. If you choose to use a sump pump, make sure that the flood waters have receded from around your home completely. Remove all debris and discard what cannot be cleaned with bleach. Shovel out all mud, silt and grime to the best of your ability. Spray off dirt and stains with a water hose on a high-pressure setting. Work from the top
