Innovative Waterproofing Technology Transforms Singapore’s Construction Industry
Singapore’s construction landscape is witnessing an important transformation in waterproofing technology, thanks to a breakthrough development from Singapore Polytechnic’s Advanced Materials Technology Centre (AMTC). This innovation addresses long-standing challenges in traditional waterproofing methods, offering a more sustainable and efficient solution.
A Paradigm Shift in Waterproofing Application
Traditional waterproofing methods, which require heating bitumen with welding torches to temperatures exceeding 250°C, are being superseded by an ingenious solution – by taking off the heat. AMTC’s newly developed flowable bituminous coating eliminates the need for high-temperature application, marking a substantial advancement in construction technology.
“Traditional waterproofing methods are like cooking with a blowtorch, lugging an LPG gas tank everywhere,” explains AMTC. “They’re energy-intensive, potentially dangerous, and release harmful fumes and volatile organic compound (VOC). Our solution is more like a waterproofing glue – simple, safe, and environmentally friendly.”
Notably, the entire production process of the bituminous coating itself is also conducted at room temperature, further enhancing its sustainability credentials and operational efficiency.
Versatile Applications in Critical Infrastructure
The technology’s room-temperature application process makes it particularly valuable for sensitive areas where traditional open flames are prohibited. Its applications extend beyond conventional rooftops to critical infrastructure such as airport runways, demonstrating remarkable versatility in various construction scenarios. The application process is straightforward: pour, spread, lay the membrane, roll, and press. Within hours, the job is complete – no gas tanks or toxic fumes in sight.
Technical Excellence Meets Practical Application
The innovation’s significance lies in its comprehensive approach to industry challenges, with AMTC researchers working alongside with groundworkers. The new coating system demonstrates superior technical performance while addressing critical operational concerns:
- Enhanced safety through elimination of open flames and gas tanks, opening new market opportunity to sensitive areas where open flames are prohibited
- Significant reduction in application time, estimated up to 30% per project
- Significant reduction in VOC emissions and smoke-free application
- Stronger adhesion properties compared to conventional methods
- Compliance with Singapore Standards SS374 and SS133
Supporting Singapore’s Sustainability Goals
This development aligns seamlessly with Singapore’s Green Building Masterplan and other sustainability objectives. By utilising waterproofing-grade bitumen and eliminating the need for high-energy processes during production and application, the technology contributes significantly to reducing the construction industry’s carbon footprint.
Industry Adoption and Recognition
The innovation has gained significant traction in the local construction sector, with three established firms already licensing the technology. One notable adopter, Proof-Tech Waterproofing & Maintenance, is actively implementing this solution in their projects, demonstrating the technology’s practical viability and strong industry acceptance.
Government Recognition
The technology’s potential impact has been acknowledged at the highest levels of government, receiving attention from Ex-Deputy Prime Minister Heng Swee Keat and Minister Desmond Lee. These endorsements underscore its alignment with Singapore’s Built Environment Industry Transformation Map and broader sustainability goals.
As Singapore continues to advance its position as a leader in sustainable urban development, innovations like AMTC’s room-temperature waterproofing technology exemplify the nation’s commitment to combining environmental responsibility with technical excellence. This development not only addresses immediate industry needs but also sets new standards for sustainable construction practices.
