The Kinks 02 stepping stone, a permeable formed concrete stepping stone designed to allow a greening ground cover to grow up through the stepping stone. The Kinks 02 has been designed to create curves in a landscape design, the shape lends its self to a number of different pattern combinations. The cement material used utilises heavy industry by products from power generation and steel production in the 'Bloom' cement mix created by The Pluto Program. Bloom replaces 70% of traditional Portland cement with these heavy-industry by products, creating an environmentally friendly concrete.
