After successfully waterproofing a cold joint in one of the units in a mid-rise residential building on Lawrence Ave. E in Toronto, a repeat client of ours where we had done a series of concrete repair and waterproofing projects since February 2022, we were asked to do the same kind of repair in a different unit.
Why Waterproofing Cold Joints Is Essential
Cold joints, the intersections where two separate pours of concrete or other materials meet but do not bond, are commonly found around windows. These joints can be vulnerable to water infiltration, particularly during heavy rains or in moisture-prone areas. Properly waterproofing these joints is vital to prevent water damage, mold growth, and structural issues. Addressing cold joints ensures the longevity and integrity of buildings, maintaining a safe and comfortable environment for occupants.
Repair Process
To effectively waterproof the cold joint, our team followed a detailed process:
Surface Preparation: We thoroughly cleaned and dried the surface to ensure optimal adhesion of the sealant.
Sealant Selection: High-quality sealants suitable for the materials involved were chosen to ensure a strong and durable bond.
Application: Using expert techniques, we applied the sealant generously along the entire joint, utilizing the appropriate tools for precise application and ensuring a smooth and continuous seal.
Reinforcement: The sealant application was reinforced with fiberglass and an additional waterproofing coating to enhance durability and protection.
Drying and Curing: Following the manufacturer's guidelines, we allowed sufficient drying and curing time to ensure optimal performance.
Outcome
The newly waterproofed cold joint now acts as a reliable barrier against water infiltration, providing long-lasting protection for the unit's structure. This proactive approach helps prevent potential water damage, ensuring the residents' comfort and the building's integrity.
