Shirasu-Ton-Ton is an insulated pavement material with advanced water penetration features. It instantaneously allows water to penetrate underground, avoiding water stagnation, helping to activate soil, growth of subterranean animal life and trees, and also preventing depletion of underground water. The surface, which is porous and not slick, is a safe material for pavements, preventing heat accumulation, reducing sunlight reflection and protecting against slippage, even when wet.
