The UD Training Complex is located on the slope of a ravine in an area with certain rustic and natural qualities. An innovative solution tied to landscape bioengineering is proposed to contain the football fields’ platform, specifically the so-called “green or ecological walls.”

Green walls are retaining structures built with layers of compacted soil reinforced with geosynthetic meshes. This combination provides sufficient stability for the wall to function by gravity. This nature-based solution does not require water or concrete for its construction.

The proposed solution is an ecological wall 25 meters high and over 300 meters long, with slopes varying between 45 and 80 degrees. The exposed landscaped surface is built with a layer of selected topsoil held by coconut fabric and a metal mesh, allowing plant growth. The resulting vertical garden does not bear structural loads, which means it can be planted and irrigated without compromising the wall’s stability.

The wall is designed with irregular, organic geometry, incorporating a zigzag staircase that provides pedestrian access to the complex. The final design combines a landscaped surface with local stone gabion walls, which address height differences and serve as protective barriers at the top.

This solution aligns with the principles of the circular economy and its call to build without waste. Its construction is based on reclaiming materials from the construction site´s excavation. The wall is landscaped with local plant species, enhancing biodiversity and improving the landscape.
