Which Basement Waterproofing Method Is Right?

In this article, we will list some best basement waterproofing methods based on different foundation types and condition.

Basement waterproofing is one of the most critical tasks for your home improvement. It not only protects your home from water damage but also increases the value of your home. However, when it comes to a waterproof basement, many individuals think about which method would be best for their home. Well, this thought is evident because there are many different types of waterproofing methods available. Understanding each method will help you make a better decision. 

Concrete Block Foundations

Concrete block foundations are the most common in homes built before the 1980s. These foundations are made from concrete masonry units or cinder blocks. They are prone to leaks due to the gaps and joints between the blocks. This means water can quickly enter through these gaps, leading to basement moisture issues. Now, let’s talk about the waterproofing method: 

Poured Concrete Foundations

Poured concrete foundations are primarily found in modern homes. They offer a solid basement construction with fewer gaps and seams than concrete block foundations. As these are robust, they’re less prone to water seepage. But water can still seep in, especially if cracks develop over time. 

An exterior membrane system would be ideal for this type of foundation. The membranes, made of rubberized asphalt or other waterproof materials, are applied outside the foundation walls. 

Crawl Space Foundations 

Crawl space foundations are standard in areas with too moist soil. Waterproofing such foundations would be difficult due to poor ventilation or excessive water seepage. 

A vapour barrier installation method can work for such foundations. Vapour barriers are heavy-duty polyethylene sheets that help prevent moisture from the soil beneath the house. 

Slab Foundations 

Slab foundations are constructed by pouring a solid concrete slab directly onto the ground. These foundations are generally less susceptible to basement water issues, but moisture can still cause damage through cracks in the slab. 

Polyurethane injection systems can be used to fill and seal those cracks that may develop in the slab. In this method, a polyurethane resin is injected into the cracks, which then expands and hardens to form a waterproof seal. 

If the slab foundation has severe rising moisture issues, a combination of moisture-resistant flooring, an interior vapour barrier, and the polyurethane injection system can be beneficial. 

Homes with Flood-Prone Areas

If your home is in a flood-prone region or has high water tables, waterproofing is necessary to protect it from water damage. 

A comprehensive waterproofing system would be appropriate for this type of foundation. The entire system involves installing exterior membrane waterproofing, a high-quality sump pump system, French drains, and a backflow valve to prevent flooding. 

Brick Foundations 

Brick foundations are similar to stone foundations and are commonly found in older homes. The brick is undoubtedly sturdy and can last a long time, but it is also susceptible to water infiltration, especially at the joints and cracks between the bricks. Moreover, moisture can travel through the mortar, weakening the foundation’s integrity. 

Basement Waterproofing Maintenance and Tips 

Despite the foundation type, proper waterproofing system maintenance is essential. This will provide long-term protection to your home’s foundation and reduce the need for costly repairs. Below are some maintenance tips to follow:

• Regular Inspection is a Must: Check the walls or floors regularly for any visible signs or cracks of water seepage. If there are any cracks, they should be sealed immediately to prevent further water infiltration. 
• Maintain Drainage Systems: Ensure all drainage systems, such as gutters, downspouts, and French drains, are maintained and working correctly. If left unchecked, drains can clog over time, leading to water pooling around your foundation. 
• Proper Landscaping: Ensure the soil around your home slopes away from the foundation. This will direct water away from the walls and prevent moisture. 
• Sump Pump Installation: Individuals living in areas prone to flooding or heavy rain must consider installing a sump pump to remove water accumulating in the basement.

Wrapping Up 

In the end, choosing the right basement waterproofing method depends on your home’s foundation type and the cause of the water problem. Whether you live in a concrete foundation, brick foundation, crawl, or any other, a range of effective waterproofing methods is available. However, it’s essential to consult a basement waterproofing expert in Toronto to receive guidance on the appropriate method and related processes.
