Basements are often the most neglected part of a home. They serve as storage spaces or laundry rooms, and people forget they must be waterproofed to protect the house from water damage. This post will discuss the top basement waterproofing methods. We will explain each waterproofing method in detail so that you can select the best method for your needs.

Interior Basement Waterproofing

You can utilize several methods to waterproof your basement from the inside. These methods are usually less expensive than exterior waterproofing methods. Still, they may not be as effective in severe cases of water damage. Interior basement waterproofing methods include:

Using a Dehumidifier

It's a device that pulls moisture from the air. By reducing the amount of moisture in the air, you can also reduce the amount of moisture that seeps into your basement walls and floors. Dehumidifiers come in many sizes, so you can select one that is appropriate for the size of your basement.

To use a dehumidifier effectively, you must empty the reservoir regularly. The frequency with which you need to empty the reservoir will depend on the humidity level in your basement and the dehumidifier size. Dehumidifiers can effectively reduce moisture in your basement, but they are not a cure-all. Sometimes, you may need to use a combination of methods to achieve optimal results.

Interior Drainage System

Another common method is an internal drainage system. This system is installed below the basement floor. It has a network of pipes that carry water away from your basement. The water is then discharged to an exterior drain or sump pump. Interior drainage systems are most effective in conjunction with an external waterproofing system.

An internal drainage system is a good option if a basement is prone to flooding. This system can reduce the amount of water entering your basement and help prevent damage to your belongings.

Interior Sealants

Interior sealants are a good option if you have cracks in your basement walls or floors. These cracks can occur due to the foundation's settling, expansion, or contraction. Seepage can also occur through these cracks, leading to water damage in your home. It is relatively inexpensive and easy to do. Whether your cracks are small or large, an interior sealant will be able to fill them and prevent water from seeping through. Apply it evenly and smoothly to ensure that it adheres properly. Once dried, it will create a barrier that will prevent water from seeping through cracks. This is excellent for those on a budget.

Sump Pump

A sump pump is a great way to remove accumulated water in your basement. You can install it in the lowest part of your basement, which will pump water out of your home and away from the foundation. This is great if you live in an area with high amounts of rainfall or if you have had flooding in your basement.

Consider installing a sump pump if you want a more permanent solution to waterproof your basement. It will keep the basement dry.

Exterior Basement Waterproofing

Exterior Sealing

It's the process of sealing the outside of your home to prevent water from seeping in and causing damage. Excavate the area around your foundation, install a drainage system, or apply a waterproof coating to your foundation walls.

French Drain

Another common procedure is installing a French drain. It's a trench filled with gravel or other drainage material with a perforated pipe running through it. The pipe collects water that seeps into the trench and carries it away from your foundation.

Properly Installed Gutter Systems

Ensure that your gutter system is installed properly and maintained regularly. Your gutters should be pitched, so they drain away from your foundation. You should regularly clear them of debris so they can function properly.

Benefits of Basement Waterproofing

Prevent Structural Damage

One benefit of basement waterproofing is that it can prevent structural damage to your home. Water seeping into your basement can cause the foundation to crack or crumble. This can lead to serious problems like buckling walls, uneven floors, and even a collapse. By waterproofing, you can help avoid these costly repairs.

Reduce the Risk of Mold Growth

Another benefit is that it keeps your home healthy. Water seeping into your basement can create an environment conducive to mold and mildew growth. These fungi can cause respiratory problems, skin irritation, and other health issues. By waterproofing, you can help reduce the risk of these problems.

Protect Your Basement Flooring

Waterproofing can help protect your basement flooring. Water seeping through cracks in the foundation can damage the flooring. This can lead to warping, staining, and even mold growth. If you have carpets or other sensitive materials, water can stain them & accelerate deterioration. Waterproofing can help protect your investment and keep your basement looking great.

Prevent Basement Flooding

If your basement floods, it can cause extensive damage to your home. Waterproofing can help keep water out of your basement, protecting your belongings. It can also help you avoid the costly repairs that flood damage.


Basement waterproofing is a necessary measure to take to protect your home from water damage. Water can seep into your basement through cracks in the foundation or walls.
