A spacious and easy-to-walk sidewalk for drainage! Introducing the case study of the permeable and water-retaining paving material "Color Sand."
In Takaishi City, Osaka Prefecture, our permeable and water-retaining paving material 'Color Sand' has been adopted for the "Imagawa Promenade." The "Imagawa Promenade," constructed in March 2016, was previously a drainage channel where domestic wastewater flowed in, causing odors and insects to emerge in the summer, which troubled the residents. In response to calls from local residents for renovations that consider hygiene and safety, the river was converted into an underground channel, and our product, which excels in permeability and water retention, was used for the surface. It has transformed into a spacious and easy-to-walk promenade. 【Benefits of Adoption】 ■ Excellent water retention, capable of handling heavy rain of 30mm/h ■ The surface has fine bumps, making it less slippery even in the rain ■ No water splashing, making it easy to walk on even when the surface is wet ■ Soft walking sensation, reducing strain on the legs and back ■ Color options that harmonize with the surrounding landscape *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, 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."
