Tosk (Permeable Grating Cover / Permeable Decorative Lid)

"Highly permeable decorative cover for drainage ditches" suppresses rainwater and offers a proposal for a livable streetscape. Tosk solves multiple latent issues (landscape, sanitation, and more) all at once!

What is Tosk (Permeable Grating Cover / Permeable Decorative Lid)? "A gutter and catch basin cover that prevents trash while allowing rainwater to pass through." It is a permeable paving material made by solidifying natural dried decorative gravel with a special binder. By using a fiber-reinforced synthetic resin binder, it has the strength to withstand vehicle traffic and offers higher permeability compared to conventional permeable pavements, ensuring that no puddles form on the walking surface even during heavy rain, thus creating a safe and comfortable walking environment. The paving surface uses colorful natural decorative gravel, with about 30 different options available, providing a highly design-oriented lineup that can match any landscape. We recommend the upgraded Tosk for solving various urban development challenges such as "heavy rain disaster measures, landscape improvement, pest control, barrier-free access, anti-slip, etc." *For details, please request a catalog from "Contact Us" or view the PDF data from "Download"

Applications/Examples of results

<Tosk (Permeable Products) Main Features> 1. Excellent permeability. Water flows through while blocking debris. Instead of draining water through a steel grid like conventional grates, it drains through the gaps in the gravel! Water flows while preventing the flow of debris. 2. Adaptable to a wide range of locations. Creates beautiful landscapes. Lightweight and portable by hand, allowing for manual installation. Reduces labor and costs! Additionally, the natural stone finish enhances the landscape. 3. Safety and high durability. Contributes to barrier-free access. Compared to traditional grates, it prevents tripping in high heels and allows safe passage for strollers and wheelchairs. The use of natural stone also reduces slipping while walking. 4. Outstanding hygiene benefits. The closed surface is often seen as a breeding ground for pests, but it proactively prevents such issues and shuts out the emergence of vectors! Furthermore, it blocks habitats and pathways for recent pest problems like rats and weasels, preventing the emergence and spread of pathogens, greatly enhancing hygiene. ~ Not only for public facilities but also for private venues where people gather, solving landscape, barrier-free access, and hygiene issues all at once! Tosk has numerous successful implementations! Please contact us ~

Rainwater drainage suppression & barrier-free, plus hygiene issues! Instead of draining through a steel grating like conventional grates, it drains through the gaps in the gravel. The gravel is solidified with a special binder (fiber-reinforced synthetic resin) and poured into a metal frame (SS.SUS). Without filling the gaps between the gravel, it allows water to flow while preventing the flow of debris with a special adhesive property. "A drainage channel and catch basin cover that prevents debris while allowing only rainwater to pass." Tosk offers a proposal for creating a livable city by suppressing rainwater!
