Basements are a crucial part of most houses, as they provide extra living space, storage, or utility areas. But this will become a headache for the owners when water starts seeping in. Water seeps into basements through cracks in the foundation or walls, leading to the growth of mould, mildew, and, potentially, structural issues.
To address this issue, waterproofing basement is the most effective solution. This is the solution for securing your basement against water intrusion and averting possible harm. There are various methods available for waterproofing basements, each with its advantages and disadvantages.
In this blog, we’ll break down the leading causes of basement moisture, different methods for basement waterproofing, and the benefits of waterproofing your basement.
Effective Methods for Basement Waterproofing
Choosing the proper methods to waterproof a basement is crucial. Let’s explore the effective techniques for waterproofing basement:
Interior Sealants and Coatings
Interior sealants and coatings are one way to waterproofing basement. In this process, applying sealant to the walls and floors of the basements is involved. Water will seep through the cracks, pores, and gaps, particularly in areas with high groundwater or inadequate drainage in the basements. This can cause water damage and mildew, potentially leading to structural issues.
Interior sealants create a waterproof barrier that will prevent water from entering through cracks and pores. However, this method is practical and valuable for minor water damage; it does not address the underlying causes of moisture problems.
Exterior Basement Waterproofing
This waterproofing basement method, i.e., exterior basement waterproofing, is necessary when water seeps in from the outside of the foundation walls. In this process, digging around the foundation involves applying a waterproof coating or membrane to the exterior walls of the building. This is an effective method for preventing water damage and maintaining the building’s internal structure.
This method can be expensive, as digging is necessary, and additional landscaping or repairs may be required after the waterproofing is complete. This approach provides the most dependable and durable way to prevent water intrusion, except for the inconvenience.
Interior Basement Waterproofing
This waterproofing basement, i.e., interior basement waterproofing, is an effective solution when the cause of the moisture is condensation. This method directs water that enters through the floor or walls to a drainage system, where a sump pump expels it.
Typically, a drainage pipe is installed beneath the basement floor and slopes in the direction of the sump pump pit, located at the lowest point in the basement. The sump pump automatically turns on and moves the water out of the basement and away from the foundation when the water level reaches a certain level.
Foundation Crack Injections/ Filters
This waterproofing basement method involves injecting fillers or sealants into the cracks in the foundation walls from the inside, eliminating the need for excavation around the foundation. Inside the cracks, liquid epoxy and polyurethane are injected, where they will harden to form a water-resistant barrier.
This technique is most effective when the cracks are minor and do not significantly compromise the structural integrity of the building. This method involves minimal disruption to the occupants and is fast.
However, it is essential to remember that injections or filling your basements can only offer a short-term solution and do not address the actual cause of the cracks and gaps. It might be necessary to make extra waterproofing efforts for both new and old cracks. More repairs will be required for deeper or larger cracks.
Understanding the Root Causes of Basement Moisture
There are several reasons for basement moisture. Let’s see some of the main reasons:
1. Hydrostatic Pressure
Hydrostatic pressure is a primary cause of moisture in basements. In this, water will seep through the wall or foundation cracks. This will result in inadequate drainage systems or pressure from the surrounding soil.
2. Monsoon Rains
In the monsoon season, heavy rains can soak the ground near the foundation of your building area. This extra moisture can then seep into cracks, joints, or porous concrete walls, leading to water seepage that will be treated by waterproofing basement.
3. Condensation
Condensation is another primary reason for your basement moisture problems, which can be addressed through interior waterproofing of the basement. This occurs when warm and humid air comes into contact with cooler surfaces, such as walls or pipes, and creates water droplets.
4. Improper Drainage System
Poor or clogged drainage systems around the building can cause water to pool around the foundation, increasing the risk of basement flooding or seepage.
5. Inadequate Grading
If the ground around your building is not graded correctly, then water can accumulate easily and eventually seep into the basement, potentially causing damage.
Key Benefits of Waterproofing a Basement
Here, we will see how waterproofing the basement gives benefits to your building:
- Waterproofing the basement is an effective way to decrease the moisture level, which will help to improve the air quality of your building.
- It helps prevent damage to basement floors and extends their life by protecting them from moisture.
- Waterproofing the basement also reduces the risk of flooding and the damage caused to your property by stopping the water from seeping into your basement.
- Water damage can reduce the internal structure of your building—waterproofing protects it and helps it last longer.
- Additionally, waterproofing your basement walls can help reduce moisture levels in your building, which in turn can lower energy costs, as your HVAC system will not have to work as hard to maintain a comfortable temperature.
Conclusion
Waterproofing the basement is a good method to protect your building or home from water damage, mould, and structural issues. Understanding the root cause of the moisture in your basement and selecting the appropriate method for addressing it helps you keep your basement dry and safe from humidity.
