Reynolds Polymer Technology creates world’s tallest indoor waterfall

Indoor waterfall at Singapore's Jewel Changi airport

The world’s tallest indoor waterfall, which officially opened on April 17 at Jewel Changi Airport in Singapore, awes travelers with a breathtaking 40-meter-tall water display. Known as the HSBC Rain Vortex, the feature was designed and built by Reynolds Polymer Technology Inc. (Grand Junction, CO).

“Jewel Changi Airport is our single largest installation of acrylic panels to date—at 719 square meters of surface area, it is the biggest monolithic piece of acrylic ever engineered,” said Mark Johnson, Vice President of Global Sales and Marketing at Reynolds Polymer Technology. “Through our strategic conceptualization and manufacturing processes, we were able to seamlessly help bring the overall vision for this phenomenal component to life.”

The acrylic feature extends into the structure’s basement and is composed of 24 panels on top and 16 panels at its base. All the panels were bonded on site using Reynolds Polymer Technology’s state-of-the-art bonding processes to produce a seamless display. The structure weighs 59 tons and is 15 meters tall. Each panel is approximately 70 mm thick; approximately 40 panels were used to compose the structure in its entirety.

Bart Baker, Vice President of Global Operations at Reynolds Polymer Technology, commented on the project: “Our operations team was beyond excited to have the opportunity to build this one-of-a-kind acrylic structure. We utilized custom and signature methods and strategies to create the best end result possible. Due to the sheer size and massive dimensions of the structure, we were tasked with assembling it on site, [including building] a cleanroom and oven around the entire structure for seamless bonding.”

Located at the central core of the terminal complex, the HSBC Rain Vortex transforms into a stunning light and sound show in the evening, and is visible from the dining terraces surrounded by lush greenery. Jewel is the newest development at Singapore Changi Airport, and its design is intended to unify Changi’s three terminals while bringing travelers and local residents together through the nucleus of the orb-like structure.
