Earth-based slag pavement that solves the weaknesses of earth-based pavement.
By using blast furnace crushed slag as the main aggregate, we have eliminated the peeling and flaking that were seen in the initial stages of conventional earth pavements. The durability is also excellent due to the slag's "latent hydraulicity" (a characteristic where strength increases over time due to hydration reactions). It has a natural color and texture similar to soil, without the artificial impression often seen in asphalt or resin-based materials. It also excels in functions such as permeability, water retention, and slip resistance. 【Features】 ■ Main composition of blast furnace crushed slag mixed with sandy soil ■ Resistant to water overflow on the surface, accommodating heavy rainfall of 30mm/h ■ Mitigates the heat island effect through evaporation from the surface ■ Provides moisture to trees and flowers through evaporation, promoting growth ■ Universal design that is easy for anyone to walk on ■ Extended lifespan compared to conventional paving materials ■ Reduces the extraction of natural materials by using artificial aggregates (recycled materials) *For more details, please refer to the PDF document 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."
