Infrastructure, Amsterdam

Type: Exterior plaster, renovation, bridge structures
Green facade surface: 50 m²

Project description:
This project involves bridge abutments in Amsterdam where graffiti has become a persistent challenge. The Municipality of Amsterdam aimed to explore ways to discourage graffiti by integrating greenery into the infrastructure. By applying a green facade solution, the surfaces become less attractive for vandalism while simultaneously contributing to a more nature-inclusive urban environment.

For this project, the bridge abutments were finished with Mosscrete, Respyre’s bioreceptive concrete technology designed to enable moss to grow directly on structural surfaces. Mosscrete creates the right conditions for moss establishment on vertical concrete and plaster surfaces, allowing infrastructure elements to gradually transform into living green surfaces.

Unlike traditional vegetation systems, moss attaches itself using rhizoids—tiny hair-like structures that allow it to adhere to the surface without penetrating or damaging the underlying material. This makes it suitable for infrastructure applications such as bridges, where durability and structural integrity are essential.

Because this location does not have access to an active irrigation system, the project serves as an important learning case for passive greening with moss concrete. The moss growth will depend on natural environmental conditions such as rainfall, humidity, and shade. If the conditions are favorable, the bridge abutments are expected to gradually green over time.

This project therefore functions as a practical test case for applying Mosscrete in urban infrastructure and for understanding how passive moss establishment can contribute to greener cities.
