Vertical gardens in certain urban areas may become a common sight if Biological Concrete manages to go from concept to reality. The "living" building material was designed by the Structural Technology Group at the Universitat Politècnica de Catalunya in Barcelona, Spain. The Biological Concrete is designed to encourage the growth of fungus, moss, lichens and other non-root-growing greenery.
The concrete is specifically designed to inhibit plant growth. The reason behind this is because plants put down roots, and roots can damage a building. The panels encourage the growth of non-threatening plants by trapping rainwater. After about a year, the aforementioned greenery should begin to grow. Biological Concrete was designed specifically for Mediterranean climates.
