Prato Svelto consists of high-density polyethylene modules in a honeycomb design. It is a '"green concept" that respects the environment, to create car parks, alleys, driveways and parking areas. Green areas in urban centres have a specific purpose that goes beyond the aesthetic and recreational. These areas, unlike those paved with concrete, asphalt or other impermeable systems, allow the natural infiltration of rainwater into the soil, thereby mitigating the phenomena of flooding that occurs more and more often in our cities. In addition, the possible use of grassy areas in urban centres, allows the creation of green spaces, natural habitats for insects and small animals. With Prato Svelto the ground is consolidated into a lawn that can be immediately used by vehicles and that requires only normal care. The area covered in grass in prato svelto is approximately 90% and the whole area contributes to the drainage of rainwater.
