The Elements is an exclusive two-tower residential development in the Epicentrum area of Jakarta’s Golden Triangle. Jakarta, the capital of Indonesia, is the most populous city in South-East Asia, with more than 10 million inhabitants. 

High-rise residential towers represent the future here, with population expected to grow to 16 million by 2020.Located in one of the capital’s most prestigious neighbourhoods, residents at The Elements can enjoy some of the finest retail, business and lifestyle options in the city, just steps from their apartment complex. Tower 1 features 37 floors, 120 units and a private elevator. Tower 2 is 45 storeys high, with 252 units and a shared elevator.

Luxury apartment buyers have very high expectations for comfort and quiet. For Agus Koima B of Sinar Mas Land, the developer, and Andrew F Tehusijarana, with Hyundai Engineering & Construction, the contractor for this project, reducing noise was a top priority in choosing and installing a drainage system. “The main problem is the noise build-up in the pipe when you flush the WC,” says Andrew F Tehusijarana. In the past, Andrew F Tehusijarana had tried other approaches to reduce noise, including covering pipes with glass wool, without achieving the desired effect.

The dBlue acoustic plumbing solution offered a perfect combination of acoustic performance, weight, resistance and mechanical strength. dBlue is made from a state-of-the-art combination of PP polymer and sound absorbing mineral filler (PP-MD) to maximise absorbance of sound. All components in the system have been designed for maximum noise reduction. High resistance against heat and chemicals allow dBlue to be used in many applications. The secure socket connections are easy to use and minimise the installation time.

The shorter installation time was an important factor for Andrew Tehusijarana. “In addition to the noise reduction, dBlue offers easier installation, which helped us reduce working hours,” he says. “The regular site supervision also from Aliaxis helped us to improve our workmanship. The availability of stock, good after-sales service and ease of installation are among the main reasons I would recommend dBlue to other contractors.”

The noise in a soil and waste system is caused by wastewater flowing inside a drainage pipe system. The wastewater is turbulent and causes noise, as well as vibrations in the pipe structure. The vibrations are emitted directly from the pipe surface as air-borne noise and as structure-borne noise to the wall through the fixing system. The dBlue system, including pipes, fittings and bracketing, has been designed to reduce both air-borne and structure-borne noise.

Modern standards require the noise to stay within acceptable limits for everyday use, and for luxury buildings those standards are even more stringent.“ Because the pipe is noiseless, tenants on the lower floors don’t hear any noise,” says Andrew F Tehusijarana.  “And that noise reduction helps our client to sell these premium apartments.”
