Seeds and soil are incorporated directly into the slabs so as to collect water and allow plants to grow; and two layers of metal mesh are sunk into the concrete to make it stronger. The designers are only suggesting horizontal use for the moment but they are working on a vertical version of their invention. M.P.

Organic concrete: technical data
The material consists in a reinforced concrete slab with turf incorporated in a percentage ranging from 10% to 30% in order to obtain a more dispersed or a denser pattern, uncompromising its mechanical resistance. In section the concrete is interrupted by parts of pre-compressed turf reaching both sides of a 30-50 mm slab, allowing the root system of plants to connect to the ground.
