As a homeowner, one of the most important tasks you have is to maintain the integrity of your house's foundation. And when it comes to basements, waterproofing is critical to protect your home from water damage and prevent mold growth. But how do you actually waterproof a basement? In this blog, we'll be exploring various methods and techniques to help you turn that damp, leaky basement into a dry and comfortable living space. Whether you're dealing with a flooded basement or just want to prevent future water damage, we've got you covered. So let's dive in!


This is how waterproofing your basement works

1. Start with Cleaning the Area

When it comes to waterproofing a basement, cleanliness is key. Before starting any waterproofing project, it's essential to clean up the area and remove any standing water. Once the area is thoroughly dry, the next step is to seal any cracks and holes in the walls. This will help prevent moisture from seeping into your basement and causing damage. After plugging any holes, it's time to apply waterproof masonry cement and a coating to the walls. If you're considering exterior waterproofing membranes or drainage solutions, it's important to weigh the pros and cons and evaluate costs. DIY options are available, but for larger projects, it may be best to hire a professional. Remember, addressing the root cause of moisture intrusion is critical to maintaining a dry and healthy basement.

2. Apply Waterproof Masonry Cement

After cleaning the area thoroughly, the next step in waterproofing a basement is to apply waterproof masonry cement to the walls. This step is crucial as it seals the pores of the concrete and stops moisture from seeping through. Make sure to use a high-quality product and apply it thickly enough to fill all the little surface holes. After allowing it to dry, use a caulk gun with a permanent concrete crack sealer to fill any gaps or wide cracks. If needed, basement wall crack plugs can be used.

However, applying waterproof masonry cement alone may not provide complete protection against moisture intrusion. It is important to follow up with additional waterproofing coatings, such as silicate-based concrete sealers or exterior waterproofing membranes. Evaluating trade-offs with exterior drainage is also recommended. Homeowners must consider cost considerations and decide if they will take the DIY approach or hire a professional for the job. Addressing root causes of moisture intrusion is also crucial to prevent any future water damage. By following these steps, homeowners can effectively waterproof their basements and protect their homes from water damage.

3. Add a Waterproofing Coating

Once the cleaning and waterproof masonry cement application is complete, the next step is to apply a waterproofing coating to the basement walls. This coating can be brushed or rolled on thickly enough to fill all the small surface holes and cracks. Allow it to dry completely before moving on to the next step. For damp walls with seepage from outside but no active leaking, an elastomeric waterproofing coating is ideal. It works by forming a flexible membrane that can expand or contract as the wall moves due to temperature changes or shifts in the soil. Another option for concrete walls involves installing a waterproofing membrane and dimple drainage board. Whatever method is chosen, the goal is to create a barrier that prevents water from entering the basement.

4. Use Silicate-Based Concrete Sealers

After cleaning the area and applying waterproof masonry cement, the next step in waterproofing your basement is to use a silicate-based concrete sealer. This type of sealer is highly effective in reducing the porosity of concrete walls, preventing water from seeping through. Silicate sealers are also very easy to apply, and they penetrate the concrete surface deeply, providing long-lasting protection. However, if the moisture level in your concrete is high, it is best to address the root cause of the issue before applying any type of sealer. Consider the trade-offs between exterior drainage solutions and interior waterproofing to determine the best course of action. It may be worth hiring a professional to help with the decision-making and application process. Remember to factor in the costs of the different solutions and assess which option fits within your budget.

5. Consider Exterior Waterproofing Membranes

When it comes to waterproofing a basement, exterior waterproofing membranes are a popular choice. This method involves excavating around the foundation walls and applying a waterproof coating or membrane to the exterior surface. The primary waterproofing layer is typically a liquid applied membrane, and it's recommended to use two layers for added protection. However, there are some trade-offs to consider when choosing exterior waterproofing, such as the cost and inconvenience of excavation, and the potential for damage to landscaping or hardscaping. It's important to evaluate all options and consider the root causes of moisture intrusion before making a decision

6. Evaluate Trade-Offs with Exterior Drainage

It's important to evaluate the trade-offs when considering exterior drainage as a solution for waterproofing a basement. This method involves excavating the soil around the foundation and installing a drain tile, and while it can effectively waterproof the basement, it comes with some drawbacks. For one, it can be an expensive and time-consuming process. Additionally, since the drainage system is located outside the foundation, it can become clogged with debris over time, leading to potential water damage. On the other hand, using gutters, a drainage system, and interior waterproofing can be a cost-effective solution that addresses the root causes of moisture intrusion. Ultimately, it's important to consider all options and weigh the pros and cons before making a decision.

7. Decide between DIY or Hiring a Professional

When it comes to waterproofing your basement, one of the biggest decisions you'll have to make is whether to tackle the job yourself or hire a professional. While DIY options may seem appealing, it's important to consider the trade-offs. The cost of a professional may seem steep, but it's important to remember the potential costs of remedying any mistakes made during a DIY project, as well as the potential risks of not properly waterproofing your basement. Additionally, some waterproofing techniques, such as using hydroclay, are not DIY-friendly. Ultimately, the decision should come down to your level of experience and comfort with the task at hand, as well as your budget. Don't forget to weigh the cost of potential water damage against the cost of hiring a professional.

8. Cost Considerations for Waterproofing

When it comes to waterproofing your basement, cost is always a major consideration. As discussed in the previous sections, there are a variety of methods to waterproof your basement, ranging from DIY options to professional services. The cost of each method will vary depending on the size of your basement and the extent of the damage. On average, homeowners can expect to pay between $2,000 and $7,000 or more for basement waterproofing, with the national average falling around $4,920 or more. However, costs can range from $2,300 to $7,575 or more depending on the method used. The cheapest option is interior waterproofing with acrylic paint, but this may not address the root cause of moisture intrusion. Homeowners must evaluate the trade-offs between cost and efficacy when deciding on the best waterproofing method for their needs. If unsure, it is always advisable to seek the advice of a professional to ensure the best outcome for your budget.

9. The Cheapest Option: Interior Waterproofing with Acrylic Paint

For those on a tight budget, the cheapest option for waterproofing a basement is to use acrylic paint. Although it may not be as effective as other methods, acrylic paint can still provide basic protection against moisture intrusion. As mentioned earlier, basic interior waterproofing consists of various waterproof coatings, including acrylic formulas. Simply roll or brush on the coating, just as you would paint. This option is fairly easy to apply and won't break the bank. However, it's important to note that this method may not be suitable for basements that experience severe dampness or heavy water penetration. For better protection, it's recommended to consider other options such as using silicate-based concrete sealers or exterior waterproofing membranes. Before making a decision, it's essential to address the root causes of moisture intrusion to avoid potential damages in the future.

10. Addressing Root Causes of Moisture Intrusion

After taking proactive steps to waterproof a basement, it's important to address the root causes of moisture intrusion. A homeowner can spend time and money sealing a basement, but if there are issues like poor drainage around the foundation or leaks in the roof, the problem will persist. Identifying the source of the moisture is the key to long-term solutions. Professional contractors can perform tests to determine where the water is coming from and provide advisement on how to address the issue. Homeowners can also take preventative measures by ensuring gutters are clean and diverting water away from the foundation. Overall, addressing root causes will save homeowners money in the long run, as waterproofing efforts will be more effective and last longer.
