TPO Roofing Membrane at Aquatopia Aalst | Elevate EMEA

Elevate has 40 years of experience in roofing solutions that enhance building performance and protect communities. Elevate’s Roofing Membrane - UltraPly™ TPO was applied at the Aquatopia Aalst swimming pool complex. Built in 2022, the project consists of two large swimming pools, an instruction pool, a recreational area, 220-meter slides, and a multifunctional gym.

Slangen + Koenis Architecten, specialized in swimming and sports facilities, was responsible for the design, while the general contractor was Vita Group, a specialist in the development of swimming pool and sports infrastructure. Experienced roofing company Roteam was in charge of the installation of the waterproofing system on the building’s 9,200 square meter roof. They opted for Elevate's white UltraPly TPO thermoplastic membrane for a durable, reflective solution that was also compatible with the photovoltaic installation.

UltraPly TPO is a durable and environmentally friendly solution that fits into the project's design. Its light color reflects sunlight and, together with the insulation, keeps the heat out and increases the efficiency of the solar panels (4,000 square meters in total). As it contains no plasticizers, UltraPly TPO can easily achieve a lifespan of 30 to 35 years.

Roofing System Characteristics

The Aquatopia roofing system complex consists of four layers. From the bottom up: steel deck, bituminous vapor barrier, PIR insulation, and finally the UltraPly TPO roofing membrane. The latter was fully adhered over the PIR insulation boards with bonding adhesive using a spreader for speed of installation.

More than 90 square meters could be sealed with one panel of UltraPly TPO membrane (using 3.05 wide x 30.5 m-long rolls). This resulted in fewer seams on the roof and, above all, an unprecedented installation speed. The weather conditions were no obstacle, as the hot air machine settings used to weld the seams together can be adjusted to colder temperatures. This means that the UltraPly TPO membrane can be installed all year round.
