Geosynthetic protection in Hungary

Living Danube, a wastewater treatment plant project in Budapest, is currently under construction with a goal to aid the general recovery of the Danube River and to provide continued environmentally sustainable management of the river.

According to a DuPont press release, an earlier stage of the project was completed this year, including a 10,0000m2 green roof that was built with DuPont’s Typar geosynthetic materials. For this project, the green vegetation surface was designed to absorb airborne dust and impurities, diminish noise, and retain up to 90% of water, preventing rainwater from draining into the sewer.

The company release stated that more than 78,000m² of geosynthetic fabric— a spunbonded, nonwoven made of 100% polypropylene continuous filaments—was specified for the project.

Bellavics László, founder of the Hungarian Green Roof Builders Association who designed the Living Danube, noted the strength and durability of the geosynthetic, providing longer life for the green roof. “Another advantage is that its pores do not clog with soil particles, which guarantees its long-term filtration ability,” he said.
