Our company has been certified as a business that produces and holds excellent products and has been selected as a "Sales Channel Development Support Business" for the fiscal year 2025. The target product is the "Tosk Reuse Cover," which can be filled into existing grates. By filling existing grates with Tosk (permeable natural stone paving material) solidified with an epoxy fiber synthetic resin binder, we have achieved a beautiful landscape that does not allow large debris to flow through, while ensuring good drainage, cost reduction, and a shortened construction period.
