Infrastructure, Hoofddorp

Type: Exterior plaster, renovation, bridge infrastructure / noise barrier
Green facade surface: 300 m²

Project description:
This project in Hoofddorp involves the renovation of an existing noise barrier that required either replacement or refurbishment. In addition to structural renewal, sound reduction was an important performance requirement for the site.

For this reason, the project implemented Mosscrete, Respyre’s bioreceptive concrete technology that enables moss to grow directly on facade surfaces. Mosscrete is engineered to create favorable conditions for moss establishment on vertical structures, allowing infrastructure elements to gradually develop into living green surfaces.

The choice for moss concrete also supports passive greening, meaning the moss develops using natural environmental conditions such as rainfall and humidity rather than relying on an active irrigation system. This approach reduces system complexity and maintenance requirements compared to conventional planted green walls.

In addition to supporting local biodiversity, moss also has natural sound-absorbing properties due to its soft, porous structure. By retaining moisture and air within the moss layer, it can contribute to reducing sound reflections and improving the acoustic performance of the noise barrier.

Through the application of Mosscrete, this infrastructure project demonstrates how functional urban structures—such as noise barriers—can simultaneously contribute to greener cities while maintaining their technical performance requirements.
