Perfect for green infrastructure initiatives! This paving material boasts excellent durability, along with permeability, water retention, and aesthetic appeal.
The initiatives for green infrastructure have been recognized in the park shown in the photo. The permeable and water-retaining paving material 'Color Sand' utilizes 'blast furnace crushed slag,' an aggregate with a fine porous structure, achieving high permeability and water retention. Depending on environmental conditions, its durability is approximately 15 to 20 years. It has a texture similar to soil, making it easy to blend into natural landscapes as 'slag pavement.' Choosing a gray tone can match urban landscapes as well. It allows rainwater to permeate and return to the ground, alleviating the 'heat island phenomenon' in urban areas. It is designed to minimize puddles and has a high slip resistance, making it easy to walk on during and after rainfall. **Features** - Excellent functionality (permeability, water retention, freeze resistance, durability, slip resistance) - Uses aggregates specified for procurement under the Green Purchasing Law, with a recycling rate of over 80% - Meets the 'road surface requirements' needed for sidewalks and bicycle paths - Over 1,800 instances of adoption in 'public works' ordered by municipalities nationwide - Perfect for the recently highlighted initiatives of 'green infrastructure' (permeability and water retention) ★ Currently, we are offering a 'collection of adoption examples' for parks and building exteriors.

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."
