Say goodbye to the dampness and hello to a cozy and comfortable basement. Let’s dive in and make it happen!

Basics of Waterproofing

If you want to ensure that your basement walls are waterproof, it’s important to understand some basics. One of the crucial factors to keep in mind is hydrostatic pressure, which is the force exerted by groundwater on the basement walls. This pressure can lead to water seepage, causing dampness in the basement. To prevent this, you can use interior waterproofing methods.

One of the key steps in interior waterproofing is applying a waterproof coating to the basement walls. This coating acts as a barrier, preventing water from seeping through and causing damage. Before applying the waterproof coating, it’s essential to clean and prepare the walls thoroughly to ensure that the coating adheres correctly. Moreover, addressing any gaps or cracks in the walls is critical to prevent water seepage.

Another important aspect to consider is the basement floor. If water is seeping through the basement floor, you may need to install a drainage system or apply a waterproof coating to the floor. This will help redirect any water seepage away from the basement walls and towards a drainage point.

Identifying the Source

Identifying the source of water infiltration in your interior basement walls is crucial to effectively waterproofing your basement. To determine where the water is coming from, you can inspect the walls for wet streaks, which can indicate the entry points. You need to pay close attention to areas such as cracks, corners of windows, mortar joints, and pipes. Conducting a condensation test can also help identify the source of moisture. If the foil test shows the underside of the foil is wet, it indicates that water is seeping through the wall from the outside. If the underside of the foil is dry, the moisture is likely originating from a different source in the basement, such as a basement shower. 

It’s important to identify the source of water intrusion accurately before proceeding with interior basement waterproofing systems. This is because existing coatings may need to be removed, or different interior systems may be required to address the moisture problems effectively.

Preparing for Waterproofing

Before waterproofing your basement walls from the inside, it is important to prepare the space. Start by removing any standing water and ensuring the basement is dry. This is necessary because waterproofing coating products only adhere to dry surfaces. You can get rid of any water on the floor using a utility pump and discharging it away from the basement. Once the basement is water-free, you can proceed with the preparation process.

Check the foundation walls for any cracks or damage that may need to be repaired before waterproofing. Pay special attention to areas where water may be seeping through, such as around windows, corners, and along mortar joints. If you find any cracks, fill them with hydraulic cement to create a watertight seal.

Make sure to inspect the exterior of the basement for any signs of water infiltration. If you notice any issues, such as poor grading or improper drainage, consider addressing them before waterproofing the interior. Exterior waterproofing methods, such as installing a drainage system or applying a waterproof membrane on the outside of the basement wall, can greatly reduce basement water problems.

Once the space is dry, and any necessary repairs have been made, you can proceed with the interior waterproofing process. This may involve applying a waterproof paint or coating to the walls or installing a drainage system inside the basement to direct water away. Keep in mind that if you have crawl spaces in your basement, they should also be inspected and waterproofed as necessary.

Waterproofing Techniques

Before waterproofing your basement walls from the inside, it is essential to prepare the basement by addressing any cracks or damage in the foundation walls and resolving any exterior issues. Once this is done, you can move on to the effective techniques for waterproofing.

One popular method is the installation of an interior French drain. This involves creating a trench along the perimeter of the basement and installing a drain pipe that collects any water that seeps through the walls. The water is then directed to a sump pump, which pumps it away from the foundation.

Another technique is applying a waterproof sealant to the concrete basement walls. This sealant creates a barrier that prevents moisture infiltration. Proper cleaning and preparation of the walls before applying the sealant is important to ensure proper adhesion.

Lastly, sump pump installation is a crucial step in basement wall waterproofing. A sump pump is a device that collects and removes water from the basement, preventing it from accumulating and causing damage. It is typically installed in a sump pit and activated when water levels rise.

Window Well Leaks

To prevent water from seeping into your basement through the window wells, there are some steps you can take. Window wells are a common source of water damage, and it’s crucial to address this issue to protect your basement from further damage. One effective method is to fill the window well area with gravel, which helps disperse rainwater. Additionally, you can create a watertight seal by caulking around the window with a masonry caulk. Another option is to install a sloped window well cover to direct rainwater away from the window well. If possible, consider installing a window well drainage system to further prevent leaks. Lastly, inspect and maintain your basement windows regularly to ensure they’re in good condition.
