Wet and musty basement gives a headache to homeowners and needs to be addressed to achieve a healthy and comfortable residential environment. Therefore in this article, we will focus on strategies that you can take to fix leaky basement from inside.
How to fix a leaky basement from inside?
1) Find the source of the water leakage.
In order to address leaky basement first, you have to determine the source of the water leakage. There are two sources of water or moisture leakage in the basement. The first source is indoor humidity which condenses on cold surfaces. The other source is water or water vapor which comes from the outside. Water from outside is usually from rainwater, melting snow or groundwater which saturates the soil around your foundation and leak in.
Water can also penetrate through cracks, or it can leak in through masonry walls or porous concrete in the form of water vapor. In order to figure out what’s causing the water leakage, use a tape to attach aluminum foil to your basement wall and inspect it after a few days. If you find moisture on the outside surface of the foil this means a high indoor humidity, while the presence of moisture behind the foil indicates moisture is leaking through the walls.
2) Get rid of excess humidity.
The next step involves eliminating excess humidity from your basement. This can be achieved through the following ways. The first step is to use aluminum foil tape to seal any leaky dryer vents to prevent unwanted humid air from entering your basement. You can also add a vent fan to your basement bathroom and make sure your family turns it on during showers to keep away moisture when showering.
Additionally, you should ensure that you keep your basement windows closed during humid weather. If you continue experiencing condensation on cool surfaces on your basement walls, you can consider running a dehumidifier to assist in lowering the indoor humidity.
3) Insulate Pipes.
In case the source of excess humidity in your basement is as a result of condensation dripping from cold pipes, you should insulate the cold water pipes with foam pipe insulator to prevent further condensation.
4) Insulate Walls.
If you determine that the source of moisture is not from the outside you can consider insulating the basement walls during the cold climates to prevent condensation of moisture on the walls. This will help you in ensuring that you prevent the occurrence of dump condition in your house.
5) Waterproof the Basement Walls
You can also use waterproofing materials that go on similar to paint to fill the pores in the masonry or concrete walls in your basement. This prevents water from further leaking in. To attain good result you should apply these coating on bare concrete or masonry walls. Therefore you should start by removing loose material using a wire brush and clean off any white powdery using masonry cleaner. Then apply a well spread out layer of the waterproof material. Give it time to dry before applying the second layer.
