Recently, Joint Seal Waterproofing undertook a project at a low-rise residential building on Dundas St. in Burlington to waterproof a ventilation shaft. Ventilation shafts are crucial for ensuring airflow and maintaining indoor air quality in residential buildings, but they can also be susceptible to water infiltration, which can lead to corrosion, mold growth, and structural degradation over time. In this project, the team implemented a multi-layer waterproofing approach to provide comprehensive protection and extend the life of the ventilation shaft.
Repair Method
The repair process began with thorough grinding and cleaning of the shaft's floor to remove loose debris and contaminants. This step was essential to create a clean surface that ensures optimal adhesion of the waterproofing layers. Next, the surface was regraded to facilitate proper water drainage, preventing future pooling and water-related damage. An industrial-strength adhesive was then applied to the prepared surface, followed by the installation of a fibreglass reinforcement layer. The fibreglass adds strength and flexibility to the system, enhancing its ability to bridge any minor cracks or surface imperfections. Finally, the shaft was coated with an epoxy membrane, which forms a seamless, durable waterproof barrier that can withstand harsh environmental conditions.
Why Waterproof Ventilation Shafts
Waterproofing ventilation shafts is a vital maintenance step for residential buildings. These shafts are often located in areas that are difficult to access, and any leaks or water infiltration can quickly lead to the deterioration of building materials, damage to mechanical systems, and mold growth that compromises air quality. By effectively sealing these areas, property managers can prevent costly repairs, reduce health risks for residents, and maintain the building's structural integrity. The implementation of a robust waterproofing system not only addresses existing issues but also serves as a proactive measure to extend the lifespan of the building.
Benefits of Our Repair Method
The multi-layer approach used in this project, including the fibreglass reinforcement, offers several key benefits. The combination of materials provides a flexible yet resilient barrier that can adapt to structural movement while maintaining its waterproofing properties. The fibreglass layer acts as a reinforcement, enhancing the tensile strength of the system and enabling it to resist cracking or delamination over time. The epoxy membrane, with its chemical and abrasion resistance, offers long-lasting protection against moisture penetration and harsh conditions. This comprehensive system ensures that the waterproofing will remain effective for years, providing peace of mind to building owners and residents alike.
