Water damage in the basement can be dangerous and will affect the health of everyone in your house. When water seeps into the basement, it eventually evaporates into water vapor. After evaporating, it can seep into the rest of your house and cause damage throughout. That’s why you should always waterproof your basement to ensure that mold and fungus stay out of your home.

Finding the Cause

Before you waterproof your basement, you have to make sure there is no water damage to begin with. Any sealant you lay down can be ineffective if there are already spots where water is coming in. You have to seal these spots before doing a general treatment.

3 Ways to Waterproof Your Basement

The best way to find out if water is getting into the basement is by finding any dark spots or rings. These are a sure sign that water is getting into the room. Otherwise, you should look for dark spots on the walls that are good indicators of mold.


After figuring out the trouble spots, you are ready to waterproof your home. The following are some of the common forms of waterproofing.

1. Sealant

This is applied much like caulk or spackle and spread along cracks and other damage on the walls where water is possibly getting through. For the most part, you will have to apply sealant if there are any signs of water damage before going through and applying a more general waterproofing solution.

The sealant expands in the cracks as it dries and chemically adheres to the surface, but it can only be applied to certain surfaces, like exposed rock or concrete. You cannot apply sealant to paint because it will not react with the surface.

2. Waterproof Paint

This is applied much like regular paint and is important for areas that are exposed to water over time. Regular paint is prone to water damage over time. This is especially true for latex or water-based paint, which is soluble in water and therefore will crack and peel when exposed to water.

The waterproof paint can be applied directly over sealant as well to add a double layer of protection. You should always make sure you apply sealant to cracks and other areas before painting to ensure that the water stays out of the basement altogether.

3. Exterior Protection

Despite all your best efforts to keep water out from within your home, your best defense will come from outside. You have to work to make sure water stays out of your home by creating an efficient drainage system that directs the water away from the basement and the house when it rains.

The basement is a great area for storage and appliances for utilities, but its location underground can make it hard to keep water out. You have to take special measures to waterproof your basement in order to avoid future damage to your home. Water damage can eventually affect your health, as well as the health of your loved ones.
