The CaixaForum Vertical Garden in Spain—the country’s first and largest continuous vertical garden—represents a significant innovation in urban gardening. This garden has become an icon of Madrid, home to 15,000 plants across its 460 m² without the need for soil.
Location: Madrid, Spain
Year: 2007

To create an efficient irrigation system for a vertical garden that requires precise distribution of water and nutrients to each plant. In addition, the goal was for the garden to function as thermal insulation and a cooling system, thereby reducing consumption of energy.
AZUD implemented its system for anti-drain drip irrigation using the technology AZUD NAVIA ND, designed to accommodate sites with significant topographic variations and high-yield crops.
NAVIA is the model of Self-compensating, anti-drain online drippers with pricked tips which is suitable for both irrigating facilities with significant topographic variations and high-yield greenhouse crops.
This cutting-edge technology combines a wide self-compensation range with excellent uniformity in the application of water and fertilizers.


The AZUD pulse irrigation system has transformed the CaixaForum Vertical Garden into a prime example of how advanced irrigation technology can enhance sustainability and efficiency in urban landscaping projects. The garden has not only enhanced the urban landscape aesthetically but has also contributed significantly to the building’s energy efficiency, establishing itself as a landmark in urban landscaping innovation and environmental sustainability.
