Pressurised
System

World-first
two-phase
drainage

The psBalcony™ system is a world-first pressurised two-phase drainage system specifically engineered for balconies and podium decks. It addresses a critical engineering challenge that conventional drainage systems fail to solve: managing extreme rainfall on exposed, high-rise surfaces without flooding.

The system uses a patented two-phase pipe flow technology, where air and water are simultaneously transported under pressure — enabling drainage of large volumes of rainwater through small-diameter pipework without the risk of backflow or surcharge.

Two-Phase Flow
Feature 01
Two-Phase Flow Technology
The patented two-phase pipe system transports air and water simultaneously under pressure, enabling efficient drainage without gradient requirements and eliminating conventional backflow risks.
Flood Prevention
Feature 02
Flood Prevention
Engineered to handle the highest recorded tropical rainfall intensities — the psBalcony™ system ensures balconies and podium decks remain clear during extreme weather events.
The Pinnacle @ Duxton
Feature 03
Proven in Landmark Projects
The psBalcony™ system has been installed in Singapore's The Pinnacle @ Duxton and numerous other landmark residential and mixed-use projects across Asia Pacific.
Applications

Where psBalcony™
makes the difference

Application 01
High-Rise Residential
Ideal for apartment balconies in high-rise towers where conventional drainage falls short of managing tropical rainfall intensity, and where backflow into habitable spaces is unacceptable.
Application 02
Podium Decks
Large exposed podium deck areas in mixed-use developments benefit from the psBalcony™ system's ability to handle high rainfall volumes with minimal pipework penetrations through the deck structure.
Application 03
Covered Linkways & Terraces
Semi-exposed terraces, skygardens and covered linkways where conventional gravity drainage is impractical due to structural constraints or limited fall available for gradient pipework.
