Curtain Wall Injection Systems

Professional Curtain Wall Injection Systems Toronto

As a leading commercial waterproofing contractor in Toronto and the GTA, Nusite Group specializes in curtain wall injection systems—a highly effective waterproofing technique used to create a comprehensive waterproof barrier behind and around commercial buildings and structures. This advanced method involves injecting specialized waterproofing materials into the soil or substrate adjacent to foundation walls and structural elements.

With over 30 years of experience in commercial waterproofing, our curtain wall waterproofing solutions are particularly effective for stopping water ingress in situations where direct access to the leaking surface is difficult or impossible, such as behind retaining walls, basement walls, tunnels, and dams in commercial projects throughout Toronto and the surrounding GTA.

Why Curtain Wall Injection Systems Are Essential for Commercial Buildings

Waterproofing Hard-to-Reach Areas: Ideal for commercial projects where direct surface treatment is impractical, such as behind foundation walls or underneath foundations in Toronto’s diverse commercial building landscape.

Sealing Extensive Leaks: Provides a comprehensive solution for extensive water ingress issues in commercial buildings that cannot be addressed through surface treatments alone.

Preventing Groundwater Infiltration: Forms a continuous waterproof barrier that prevents groundwater from reaching the structural elements of commercial properties throughout the GTA.

Structural Integrity: Helps to stabilize and strengthen commercial building foundations by filling voids and consolidating loose soils commonly found in Toronto’s varied geological conditions.

Types of Curtain Wall Injection Systems for Commercial Applications

Polyurethane (PU) Curtain Injection

Hydrophilic PU: Expands in the presence of water to form a flexible, watertight seal around foundation walls. It can penetrate fine cracks and soil pores, making it highly effective for commercial waterproofing applications in Toronto’s challenging climate conditions.

Hydrophobic PU: Repels water and forms a rigid waterproof barrier. This solution is suitable for areas of commercial buildings where flexibility is not required but a strong structural seal is essential.

Acrylic Gel Curtain Injection

Acrylic gels are low-viscosity materials that can penetrate very fine cracks and pores in the soil and substrate surrounding commercial buildings. They form a highly flexible and durable waterproof barrier that performs exceptionally well in Toronto’s freeze-thaw cycles.

Silicate-Based Injection

Silicate-based materials, such as sodium silicate, react with calcium hydroxide present in concrete foundation walls or soil to form a gel. This type of injection is often used for damp-proofing and stabilizing loose soils in commercial projects throughout the GTA.

Cementitious Grout Injection

Cement-based grouts are used to fill large voids and stabilize soil around commercial building foundations. While effective for structural reinforcement, they are less flexible compared to other materials and are typically used in less dynamic environments.

Professional Application Process for Commercial Projects

Site Assessment: Our experienced commercial waterproofing contractor team evaluates the commercial building area to determine the extent of water ingress and the best injection material to use based on Toronto’s specific soil and climate conditions.

Drilling Injection Ports: We drill holes through the structure into the surrounding soil or substrate at regular intervals, ensuring minimal disruption to commercial building operations.

Installing Injection Packers: Our technicians place injection packers or ports into the drilled holes to control the flow of the injection material and ensure proper waterproof barrier formation.

Injection: We inject the selected waterproofing material through the packers under pressure, allowing it to spread and create a comprehensive barrier around foundation walls and structural elements.

Curing: The injected material is allowed to cure and form a solid, waterproof barrier that provides long-term protection for commercial buildings.

Inspection and Finishing: Our team inspects the site to ensure the waterproof barrier is effective and performs any necessary surface finishing to restore the commercial building area.

Advantages for Toronto Commercial Buildings

Non-Invasive: Can be applied to commercial buildings without extensive excavation or disruption to business operations—crucial for active commercial projects in Toronto and the GTA.

Comprehensive Coverage: Provides a thorough waterproof barrier around and behind foundation walls and structural elements of commercial buildings.

Versatility: Suitable for various types of commercial buildings and soil conditions found throughout the Toronto area.

Long-Term Solution: Offers durable and long-lasting protection against water ingress for commercial properties, backed by our over 30 years of experience in commercial waterproofing.

Climate Resilience: Specially designed to withstand Toronto’s harsh winters and seasonal ground movement that can affect commercial building foundations.
