Interior Waterproofing

Interior waterproofing is a method of preventing water intrusion within the internal spaces of a building, such as basements or any areas susceptible to water exposure. This process involves applying specialized waterproof coatings, sealants, or membranes to the interior surfaces, creating a protective barrier that prevents water from seeping through walls and floors. Interior waterproofing is particularly useful for existing structures where external waterproofing may be challenging or impractical. By addressing water-related issues from the inside, this approach helps maintain a dry, safe, and moisture-free environment, safeguarding the building’s integrity and protecting valuable assets from potential water damage.

Exterior Waterproofing

Exterior waterproofing is a crucial technique used to protect a building from water infiltration by addressing the issue at its source – the exterior surface. This method involves applying waterproof coatings, membranes, or sealants on the outside walls, foundation, and other vulnerable areas of the structure. By creating a robust and impenetrable barrier, exterior waterproofing prevents rainwater, groundwater, and moisture from penetrating into the building, thus safeguarding it against potential water damage, mold growth, and structural deterioration. This proactive approach to waterproofing is particularly effective for new constructions or during major renovations, ensuring long-lasting protection and enhancing the overall durability and resilience of the building.

Our Basement Waterproofing Process

Waterproofing is a process of making a structure or material resistant to the ingress of water or moisture. It is a crucial aspect of construction and building maintenance, as water intrusion can cause significant damage to buildings, structures, and their contents over time.

Systems We Use For Basement Waterproofing

Basement Wall Systems

A damp basement in a home can cause many problems for homeowners. High humidity not only leads to the growth of mold and mildew but also quick deterioration of the building’s walls. To eliminate moisture, you must take the necessary measures.

One effective way to address high humidity is by waterproofing the walls. It blocks liquid, protecting the basement from the adverse effects of water and moisture, preventing the growth of harmful spores and fungi.

Waterproofing basement walls Toronto is one of the areas of expertise of our company. Our specialists perform waterproofing work both from the inside and outside of the basement.

We use modern techniques, equipment, and high-quality waterproofing materials. We work efficiently, are productive, and achieve top-notch results.

Basement Drainage Systems

Basement areas are typically situated below ground level. This provides them with good insulation on the one hand, and on the other hand, the temperature stability depends on the depth of the area.

It’s crucial that there are no natural sources of moisture (groundwater) in the basement or cellar area and that it is protected from the penetration of water from atmospheric precipitation or potential groundwater level rise with reliable drainage systems.

These systems remove excess water from the basement, which can be caused by heavy rain, air conditioner condensation, or leaking pipes.

Our company installs drainage systems of various types and complexities. Our extensive experience in implementing projects enables us to install efficient drainage systems in areas with complex terrain, large coverage, and unfavorable soil conditions.

Window Well Leak Waterproofing System

Basement windows serve not only as a source of natural light but also as a potential entry point for water into the space. Therefore, it’s essential that they are tightly sealed and have a reliable window well—a recess along the exterior wall of the building.

Window wells are a crucial component of a basement structure. They have the challenging task of providing natural light to basement areas while also protecting them from rainwater infiltration.

Whether you need a new window well installation or repairs to an existing one, turn to the specialists at Quality Age Build. We understand the vulnerability of basement windows and how to protect them effectively.

We offer tailored solutions for each project to ensure the highest quality outcome.

Crack Repair Systems

The strength and reliability of the foundation determine the longevity of the entire structure. Over time, natural and environmental factors can lead to wear and a loss of structural integrity.

One common issue is cracks, and their causes can be varied, including low-quality materials, errors in formwork installation, inadequate concrete compaction, and more.

If these cracks are not addressed on time, they can lead to water or moisture entering the basement and even the structural deterioration of the entire building.

Our company can help you resolve this issue. We always assess the extent of the damage to offer the most effective repair solution tailored to the size and type of cracks.

Our specialists use high-quality materials and tools, ensuring you receive a reliable and lasting repair.

Expanding the Total Living Area

Excess moisture in the basement is a persistent problem for many owners of underground or semi-underground spaces. Dealing with such an issue can be challenging but is crucial.

Elevated humidity levels can negatively impact both the structure and the well-being of individuals who regularly occupy these spaces. Additionally, excess moisture significantly limits the use of the basement area.

This is why it’s important to use air dehumidification systems. They can deal with moisture issues and maintain a healthy microclimate consistently.

Selecting the right system involves numerous calculations and should be done expertly. It’s best to entrust this stage to the professionals at Quality Age Build. We work with official and trusted equipment suppliers, ensuring the high quality of the products.

If you need any assistance in selecting an appropriate system, we’re here to help and provide guidance.

4 Ways Water Damages Your Basement:

Leaky Foundation

A leaky foundation poses serious risks to a building’s stability and overall condition. The seepage of water through cracks or gaps can weaken the foundation, leading to structural damage and potential mold growth. Timely repair and waterproofing are crucial to prevent further deterioration and maintain the longevity of the structure.

Poor Drainage

Poor drainage in your home can lead to water pooling around the foundation, causing cracks and structural damage over time. Additionally, it can result in basement flooding and increased humidity levels, creating an environment conducive to mold growth. Timely mitigation of poor drainage issues is essential to prevent costly repairs and maintain a healthy living environment.


Basement flooding occurs when excessive water accumulates and seeps into the lower levels of a building, often due to heavy rainfall, improper drainage, or plumbing issues. This can lead to significant property damage, ruined belongings, and the growth of mold and mildew. Preventative measures like proper waterproofing and maintaining functional drainage systems are essential to avoid the risks associated with basement flooding.

Sewer Backup

A sewer backup happens when the sewage system becomes overwhelmed or blocked, causing wastewater to flow back into homes or buildings. This can result in unsanitary conditions, extensive property damage, and health hazards due to contaminated water and waste. Regular maintenance of sewage systems and the installation of backflow prevention devices are crucial in preventing sewer backups.
