How Waterproofing Membranes Prevent Water Intrusion And Protect Your Home

Ensuring your home is protected from water damage is crucial for maintaining its structural integrity and value. Waterproofing membranes are essential in preventing water infiltration and the resulting damage. At Northwest Drainage Solutions, we specialize in providing top-notch waterproofing services in Thunder Bay, ON. This article will explore how waterproofing membranes work, their benefits, and why you should consider professional installation.

Understanding Waterproofing Membranes

What is a Waterproofing Membrane?

A waterproofing membrane is a layer of material applied to a surface to prevent water from penetrating the structure. These membranes are designed to be durable, flexible, and resistant to water and environmental factors. There are various types of waterproofing membranes, including liquid-applied and sheet membranes, each with its unique application process and benefits.

How Waterproofing Membranes Work:

Waterproofing membranes work by creating a barrier that blocks water from entering the protected area. When applied correctly, they seal any potential entry points for water, including cracks and seams. This barrier is vital in areas prone to water exposure, such as basements, foundations, roofs, and bathrooms.

Benefits of Waterproofing Membranes

Protecting Structural Integrity:

Waterproofing membranes play a crucial role in maintaining the structural integrity of your home. By preventing water infiltration, they protect the foundation, walls, and other structural components from water damage, which can lead to weakening and eventual failure.

Preventing Mold and Mildew:

Water intrusion can create a damp environment conducive to mold and mildew growth. Waterproofing membranes help maintain a dry interior, reducing the risk of mold and mildew, which can cause health issues and damage to your property.

Increasing Property Value:

Investing in waterproofing enhances your property’s value by ensuring it remains in good condition. Potential buyers are more likely to purchase a home with a sound waterproofing system, knowing it is protected against water damage.

Energy Efficiency:

Waterproofing membranes can improve your home’s energy efficiency by preventing moisture-related insulation problems. A dry, well-insulated home retains heat better, reducing energy consumption and lowering utility bills.

Types of Waterproofing Membranes

Liquid-Applied Membranes:

Liquid-applied membranes are applied as a liquid and then cure to form a seamless, durable barrier. They are ideal for complex shapes and areas with many protrusions. Their flexibility allows them to move with the structure, preventing cracks.

Sheet Membranes:

Sheet membranes are pre-formed sheets that are applied to the surface. They offer consistent thickness and are highly effective in large, flat areas. Installation involves overlapping the sheets to ensure complete coverage.

Cementitious Waterproofing:

Cementitious waterproofing involves a mixture of cement-based products applied to the surface. It is easy to apply and is commonly used in areas like bathrooms and wet rooms. While not as flexible as other types, it is highly effective in specific applications.

Bituminous Membranes:

Bituminous membranes are made from asphalt and other bitumen-based materials. They are commonly used on roofs and foundations due to their durability and waterproofing properties. They come in both liquid-applied and sheet forms.

Applications of Waterproofing Membranes


Basement waterproofing is crucial to prevent water intrusion from groundwater and rain. Waterproofing membranes protect against basement flooding, mold growth, and structural damage, ensuring a dry and safe living space.


Foundation waterproofing is essential to protect the base of your home. By applying waterproofing membranes, you prevent water from weakening the foundation, which can lead to severe structural issues over time.

Bathrooms and Wet Areas:

In bathrooms and other wet areas, waterproofing membranes prevent water from seeping into walls and floors. This protection is crucial to avoid mold growth and water damage, ensuring a healthy and safe environment.

Cost Considerations for Waterproofing Membranes

Factors Influencing Costs:

Several factors affect the cost of waterproofing membranes, including the type of membrane, the application area, and labor costs. The condition of the surface and any necessary repairs can also influence the overall cost.

Average Cost Ranges:

  • Liquid-Applied Membranes: $3 - $6 per square foot
  • Sheet Membranes: $4 - $8 per square foot
  • Cementitious Waterproofing: $2 - $4 per square foot
  • Bituminous Membranes: $3 - $7 per square foot

Budgeting Tips:

Plan for waterproofing expenses by considering both the immediate costs and the long-term benefits. Setting aside a budget for regular maintenance can help prolong the lifespan of your waterproofing system and avoid costly repairs in the future.

DIY vs. Professional Waterproofing Membrane Installation

Pros and Cons of DIY Installation:

Pros: DIY installation can save money and provide immediate action. It is suitable for small, straightforward projects where professional expertise may not be required.

Cons: DIY installations carry risks, such as improper application, lack of specialized tools, and potential for future leaks. These issues can lead to higher repair costs in the long run.

Benefits of Hiring Professionals:

Hiring professionals ensures the job is done correctly with high-quality materials and advanced techniques. Professionals can identify underlying issues and provide comprehensive solutions, offering guaranteed results and peace of mind.

Maintenance Tips for Long-Lasting Waterproofing Membranes

Regular Inspections:

Conduct regular inspections of your waterproofing membranes to ensure their integrity. Look for signs of wear, damage, or leaks and address them promptly.

Prompt Repairs:

Address minor issues quickly to prevent major damage. Timely repairs can extend the lifespan of your waterproofing system and maintain its effectiveness.

Cleaning and Upkeep:

Maintain your waterproofing membranes by keeping them clean and free from debris. Regular cleaning can prevent blockages and ensure the membranes function as intended.
