If your basement is leaky, waterproofing seems like the best solution. But before you start doing that, you should figure out and understand the potential causes and why this happened. Since basements are below the surface, they are more likely to accumulate too much moisture and excess water.
Here are the most frequent causes of why basements get water damaged:
Water will almost certainly leak if your walls and floors are cracked. Inadequate drainage will lead to excess water. Rainwater will collect at your home’s foundation and damage it if it’s not properly channeled away from the building.
Drainage systems that are not constructed correctly can get clogged. If the land is facing towards your home, water will tend to flow and accumulate around its foundation, damaging your basement’s integrity.
Now that you know why there is excess water, let us show you some reasons why you should waterproof your basement and how to seal them from the inside.
Reasons to waterproof
Your basement is a great storage space where you want to deposit items unwanted or unfit for your house. Additionally, it serves as your home’s structural base, so its integrity should be important. While this reason might be just enough to waterproof your basement, we’re going to give you many more below:
Waterproofing prevents flooding
Since most of the basements are located underground, they are at serious risk of flooding when severe weather. Regardless of the weather, waterproofing can help shield your house from water damage that might damage your belongings stored there.
Prevent cracks in the foundation
When temperatures fluctuate, moisture that is trapped in your basement’s foundation can expand and contract. It causes fractures that might be dangerous to the structure of your home. Fixing these leaks and waterproofing your basement will help you in the long term, eliminating any possible damage in the future.
Reduce Energy Costs
During the hot summers, the humidity in your basement will increase significantly. Therefore, you’ll have a higher energy cost when you try to cool it. As an opposite effect, your house might get cold air coming in from the foundation cracks during the winter. Your house will have better heating and cooling efficiency if you decide to waterproof your basement.
Products you will need

You want this process to be perfect. Remember, waterproofing your basement will bring you benefits for many years. Preparation steps before executing this process are necessary.
Substances used for waterproofing and sealing may only be applied directly to the surface. Otherwise, they won’t be effective. If your walls have old paint on them, use a brush or other tools to remove them. This process might be easy for some people, it is always essential to wear the appropriate safety gear while removing paint and cleaning the walls and floors of dust and debris. It includes coveralls, a respirator, and gloves.
Maybe all surfaces are clear and you have all the necessary tools and products available. Then we’re ready to begin the waterproofing process of your basement. Start by following the instructions below:
How to seal & waterproof a basement wall from the inside
- Eliminate standing water
Make sure to eliminate any standing water in your basement before starting. You don’t want your sealing procedure to be incomplete because of external factors and elements which can ruin the process.
To stop a water problem, the water must be directed away from the home’s foundation. That’s why gutters are beneficial because rainwater is collected in them and transported away. If your home lacks gutters, you should consider getting them since they are vital for the future protection of your basement.
If your home is already equipped with gutters, clean them regularly. Gutters overflowing with leaves and branches won’t function properly, and water might get directed elsewhere. This often occurs during autumn when leaves fall. That’s why during this time, the cleaning process has to be done more often.
- Patching and waterproofing the walls
It is unlikely that patching the leaks and cracks in your foundation will completely prevent water from entering the basement. However, it is an optional step that can be conducted for better results. However, you will need hydraulic cement to accomplish this since this product will stop water from entering the walls.
15 minutes after mixing, the cement is ready for use. Make sure you are prepared to apply it before you start the preparation. Hydraulic cement can harden rapidly, so it’s essential to complete this step quickly.
Your walls can also be waterproofed, which is a much more effective process. The goal is to apply enough waterproofing to the walls such that it penetrates their pores and cracks. Chemical reactions will create the blending process, and the cracks in your walls will be filled instantly.
Such products can be applied using a variety of brush strokes. By doing this, you will apply the solution exactly where it is needed while also ensuring it fills all the cracks and not only the surface. A second one can be applied as soon as the first layer has dried. Right at the end, multiple layers of paint can be applied thinly to mask the changes in your basement’s walls when the waterproofing process is finished.
- Control condensation and humidity
Condensation occurs when pipes are cold while exposed to warm air. Insulating these pipes can prevent condensation from accumulating, and it is affordable and simple to install. Such insulations are specifically made for pipes, and you’ll successfully get the job done with just a pair of scissors.
If you live in a colder climate, insulation will prevent the pipes from freezing by keeping them warm. This is an added benefit to condensation control. Also, insulation of the walls is beneficial since it helps protect against moisture. Installing wall insulation is easy since it comes in panels specifically designed and created to your preferences.
Beware not to insulate in places where water is currently leaking because you will provide a favorable environment for mold to form. That’s why you need to fix the leakage and cover the cracks with the products shown in this article. Insulation is a late-stage step that will extend the results of your work.
An additional problem is humidity. There is nothing you can do to control the humidity outside. But by utilizing a dehumidifier, you can control and lower the one present in your basement. While some dehumidifiers require draining once they are full, others will let you connect a hose to drain the water in a designated space.
If you decide to purchase humidity reduction equipment, seal tight the exhaust line from your dryer. Overall, waterproofing your basement is not difficult. However, it will provide long-lasting durability and results that you will be satisfied with. A basement with a water problem should never be ignored.
While reparations and waterproofing are required immediately, make sure to thoroughly follow the instructions and finish every step as efficiently as possible.
Waterproofing your basement is not difficult, and you don’t need to be an expert in this subject. Even if you don’t know about the complicated details of construction and the fundamentals of structural integrity, all you got to do is follow the instructions carefully when you seal. If you do it correctly, you will get exceptional results.
The most efficient way to waterproof your basement is to follow the instructions in this article and apply hydraulic cement to fix the damage to your walls.
If this method is too time-consuming or expensive for you, installing an interior drain system will also help reduce water. It is much cheaper and can be done quickly, although this is not a permanent solution.
Depending on which product you use and the size of your basement, a waterproofing operation will cost you between $1,920 and $6,493. Usually, the average cost per foot ranges from $3 all the way to $10. While this might be a significant investment, you will get results for years to come and prevent your basement from being damaged by floods or excess water.
