How to Waterproof a Foundation: A Step-by-Step Guide

A strong and well-maintained foundation is crucial for protecting your basement from various issues, such as water damage and structural instability. Here’s how a foundation plays a vital role in safeguarding your basement:

  1. Schedule and Plan Properly: Recognize peak seasons and potential delays due to weather conditions. Ensure proper layout planning in accordance with the final grade line on foundation walls.
  2. Mark Layout Lines: Use a crayon or chalk to mark lines, especially on complex foundations with varying grade. For simpler foundations, instruct the waterproofer to work a certain distance from the top of the foundation.
  1. Determine Areas to Waterproof: Waterproof any foundation wall with earth on one side and usable space on the other, including crawl spaces. Extend waterproofing at least 12 inches onto intersecting walls.
  1. Address Special Locations: Determine in advance what you plan to do at basement windows, bulkheads, porch foundations, and intersecting walls that may not need to be waterproofed.
  1. Apply Waterproofing Materials: Ensure waterproofing is as close to the finished grade as possible but no lower than 6 inches. Apply materials according to manufacturer instructions.
  1. Be Mindful of Temperature Limitations: Caution is required when working with water-based materials which have a lower limit for application.
  2. Engage Professional Help: Do not hesitate to call in experts. Waterproofing has its intricacies and a professional would have the requisite knowledge and experience to troubleshoot any unexpected challenges that might be encountered.

Surface Preparation Procedure for Foundation Waterproofing

  1. Cleaning: Clear the foundation and footings of all loose materials.
  2. Filling: Use non shrink grout or patching cement to fill large voids or honeycombs.
  3. Inspection: Examine the entire surface and address any potential issues immediately.
  4. Drying: Dry off all footings using a propane torch and sweep off standing water.
  5. Material Removal: Trim off anomalies like misaligned form ties and scrape off excess material from walls.
  6. Sweeping: Sweep off dust or mud from walls and footings to ensure waterproofing materials adhere well.
  7. Patching: Conduct the necessary patching and grouting as per the manufacturer’s instructions.

The planning and execution of each step ensures the adherence and efficacy of the waterproofing process, leading to more robust and durable foundation waterproofing.

When Should I Waterproof Foundation?

Knowing when to waterproof your foundation is crucial to prevent potential water damage and maintain the structural integrity of your home. Here are some signs that indicate it’s time to consider waterproofing your foundation:

  1. Water Seepage: If you notice water entering your basement during rainstorms or snow melting, it’s a clear sign that your foundation is vulnerable to water infiltration. Waterproofing can help prevent future water damage and keep your basement dry.
  2. Dampness or Moisture: Excessive dampness or moisture in your basement, along with a musty odor, can indicate water seepage. These conditions can lead to mold and mildew growth, compromising indoor air quality and potentially causing health issues.
  1. Cracks in Foundation Walls: Visible cracks in your foundation walls, especially ones that are widening or extending, may be a sign of foundation movement or pressure from water. Waterproofing can help address the underlying issues and prevent further damage.
  2. Efflorescence: White or grayish mineral deposits on your basement walls, known as efflorescence, can indicate water penetration. This occurs when water evaporates, leaving behind salt deposits. Waterproofing can help mitigate this issue.
  3. Sump Pump Failure: If your sump pump is frequently failing or unable to keep up with water accumulation, it may be a sign that your foundation is not adequately protected. Waterproofing can enhance the effectiveness of your sump pump system.
  4. Home Renovations: When planning significant home renovations, such as adding an extension or finishing the basement, it’s essential to include foundation waterproofing as part of the project. This proactive measure can prevent future water-related issues.

Remember, it’s best to consult with professional waterproofing contractors to assess your specific situation and recommend the appropriate waterproofing solutions. Timely foundation waterproofing can save you from costly repairs and ensure the long-term stability and protection of your home.

What Should I Know Before Waterproofing Foundation?

  1. Identify the Source of Water: It’s crucial to identify the source of water infiltration and understand the underlying cause of the problem. This will help determine the most effective waterproofing solution and prevent future issues.
  2. Professional Assessment: Seek a professional assessment of your foundation by experienced waterproofing contractors. They will inspect your property, identify any existing damage, and recommend the appropriate waterproofing method based on your specific needs.
  1. Understand Waterproofing Methods: Familiarize yourself with different waterproofing methods such as exterior excavation, interior drainage systems, or waterproof coatings. Each method has its own advantages, and the choice depends on factors like the severity of the issue, accessibility, and budget.
  2. Obtain Multiple Quotes: It’s recommended to obtain multiple quotes from reputable waterproofing contractors. Compare the services offered, warranty provided, and the overall cost. Remember, choosing the cheapest option may not always guarantee the best quality.
  3. Consider Long-Term Solutions: Look for waterproofing solutions that provide long-term protection and durability. Investing in quality materials and professional installation can save you money in the long run by preventing future water damage and costly repairs.
  4. Permits and Regulations: Check if there are any permits or regulations required for foundation waterproofing in your area. Compliance with local building codes is essential to ensure the work is done correctly and legally.
  5. Maintenance and Upkeep: Understand the importance of regular maintenance and upkeep to prolong the effectiveness of your waterproofing system. This may include clearing gutters, maintaining proper drainage, and addressing any signs of water intrusion promptly.

Remember, foundation waterproofing is a specialized task that requires expertise and experience. Consulting with professional waterproofing contractors will provide you with valuable insights, personalized recommendations, and ensure the job is done effectively and efficiently.


When it comes to shielding your foundations from water damage, it’s essential to understand the difference between dampproofing and waterproofing. These two treatments differ significantly in their level of protection, cost, application and overall effectiveness based on the situation. Here’s a detailed breakdown of dampproofing and waterproofing, showing some of the key pros and cons of each method:

Dampproofing- Lower cost
- Effective against soil moisture
- Can be combined with drainage systems
- Not effective against high pressure water (hydrostatic pressure)
- Not as durable as waterproofing
- May not be suitable for areas prone to flooding
Waterproofing- Highly effective against water intrusion, even under hydrostatic pressure
- Increases property value
- Allows full visual inspection of joints and defects
- More expensive compared to dampproofing
- Requires professional installation
- Installation can be labor-intensive if applied to existing structures

Please note that the choice between dampproofing and waterproofing should be made considering the specific needs, budget, and environmental conditions surrounding your property.
