Designed specifically for sponge city stormwater retention systems, this high-porosity hydrophilic rock wool element maximizes rainwater retention and slow release within limited spaces. It addresses the core challenges of urban flooding, wasted rainwater resources, and the large footprint of traditional facilities.
Installed in bioretention strips or sunken green spaces, it rapidly absorbs runoff during heavy rainfall and slowly replenishes groundwater or returns moisture to the atmosphere, enabling cities to "breathe" like a sponge.
Applications include water buffering, infiltration and drainage of urban rain gardens, bioretention strips, and sunken green spaces.
