The document discusses two sustainable paving technologies: grasscrete and grassroof. Grasscrete is a cast-on-site reinforced concrete system that allows for drainage while being driven on and helps balance CO2 levels. It is used in applications like carparks, roads, and embankments. Grassroof is a honeycomb cell green roof overlay that is installed on flat roofs to reduce runoff, provide insulation, and protect membranes. Both systems use recycled materials and help create greener environments.
