Achieving both permeability and water retention! This is a new environmentally friendly walking pavement material that is highly durable and resistant to slipping even when wet!
Color sand allows the invaluable water resource of the Earth, "rainwater," to permeate and be restored underground, 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" formed during rainfall, non-slip ○ Mitigates the heat island phenomenon ○ Maintains high "water retention" ○ Soft walking sensation ○ High durability ○ Difficult to raise temperatures due to the "cooling effect" of water application 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, revitalizing spring water, promoting the growth of trees and flowers, and restoring "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" access, "disaster evacuation routes," "weed prevention measures," and "school route improvements."
