The technical basis of "permeable blast furnace slag pavement" that balances permeability and water retention.
Introducing technical information about permeable and water-retaining blast furnace slag pavement "Color Sand"!
We will explain the technical basis of the "Permeable and Water-retaining Blast Furnace Slag Pavement (Color Sand)" that achieves both permeability and water retention. All of our paving materials use "water-quenched blast furnace slag" as the main aggregate. The aggregate itself has a fine porous structure, allowing it to provide both permeability and water retention. While typical permeable paving materials allow water to pass through at "points," our paving materials enable permeability across "surfaces" due to the nature of the aggregate itself, resulting in less clogging and maintaining permeability performance over a long period. Additionally, by cleaning with high-pressure washers, the permeability can be restored to about 80%. Further explanations regarding "permeability performance" and "water retention performance" can be found through external links. 【Introduction to Technical Information】 ■ Reasons for achieving both permeability and water retention ■ Permeability performance ■ Water retention performance ■ Our product lineup *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.

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."
