Achieving both permeability and water retention! With a finely textured surface that prevents water splashing, this environmentally friendly new walking path pavement material is less slippery even when wet from rain!
Color sand is an environmentally friendly new pedestrian road paving material that uses "blast furnace crushed slag," a byproduct of steelmaking, as the main aggregate, along with cement additives and inorganic pigments as secondary materials. These components are mixed and compacted using a compaction machine to finish the product. It allows rainwater, an invaluable water resource for the Earth, to permeate and be reabsorbed into the ground, alleviating the "heat island phenomenon" in urban areas, reviving spring water, promoting the growth of trees and flowers, and contributing to the creation of urban environments rich in "water and greenery." 【Features】 - Excellent permeability - No puddles during rainfall, non-slip - Mitigates the heat island phenomenon - Maintains high water retention - Soft walking sensation For more details, please contact us or download the catalog.

Company information
The permeable and water-retaining pavement materials developed by Sanwa Grand Co., Ltd. allow rainwater, an invaluable water resource for the Earth, to permeate and be returned to the ground, thereby alleviating the "heat island phenomenon" in urban areas during the summer, reviving spring water, promoting the growth of trees and flowers, and regenerating "moisture of water and greenery" in the city, creating a pavement that is friendly to both people and nature. Our company aims to contribute to society as a member of a company that creates a comfortable environment through the dissemination of these environmentally friendly pavement materials, which excel in permeability and water retention. Our pavement materials are also ideal for areas with high social needs, such as "barrier-free," "disaster evacuation routes," "weed control measures," and "school route maintenance."
