Waterproofing Solution for WOHA Green Wall Courtyard in Singapore
In 2022, Triflex Asia was approached to address significant waterproofing issues in the indoor green wall courtyard of the iconic, versatile house of the prestigious WOHA Architects Pte Ltd office. The green wall suffered from persistent leaks caused by the absence of reinforcement in the original cementitious waterproofing layer. Following an initial patch-up, a complete refurbishment of the waterproofing system was undertaken in 2024, leveraging Triflex’s expertise.
The Challenge
The indoor green wall courtyard, a central architectural feature of the building, faced severe water ingress due to the failure of the original waterproofing system. The absence of reinforcement and high moisture content in the wall exacerbated the problem, resulting in leaks that threatened the structure's integrity. The challenge involved identifying a solution capable of resisting high moisture levels while ensuring long-term durability for intricate details, such as aluminum flashing, light cable penetrations, and irrigation systems.
The Solution
In collaboration with our authorized contractor, Triflex conducted an on-site survey, followed by comprehensive moisture and adhesion tests. Based on the findings, Triflex SmartTec was selected as the ideal solution. The system was chosen for its outstanding moisture resistance (minimum 30%) and vapor barrier properties, making it suitable for high-humidity environments.
The refurbishment involved applying Triflex SmartTec to the entire green wall, including:
Aluminum flashing and light cable penetrations
Irrigation system components
Fixing points for the green wall panels
The liquid-applied waterproofing system provided seamless, crack-bridging protection, ensuring the wall's longevity and performance.
