Our company is engaged in the sale of civil engineering materials and general civil engineering work. We handle and sell various rainwater treatment products, including natural dried decorative gravel that can be directly applied to existing floors from 10mm, solidified with an epoxy fiber synthetic resin binder, known as [Tosk/permeable resin pavement], and a drainage cover that prevents debris while allowing only rainwater to pass through, called [permeable grating cover]. We also offer a lightweight reinforced rainwater storage structure called [New Pura-kun], ensuring safety and reliability. Additionally, we generate and sell a sodium hypochlorite aqueous solution/ceramic water that can suppress odors, bacteria, and viruses. Please feel free to contact us if you have any requests.
