Tosk (Permeable Grating Cover / Permeable Decorative Lid)

  • Official site

"Highly permeable decorative covers for drainage ditches" that suppress rainwater and offer 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 and allows only 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 prevention, landscape improvement, pest control, barrier-free design, slip resistance, etc." *For more details, please request a catalog by Email or download the PDF data from the "IPROS site"。

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 design. Compared to conventional grates, it prevents tripping in high heels and allows safe passage for strollers and wheelchairs, while the use of natural stone reduces slipping while walking. 4. Outstanding hygiene benefits. The closed surface is often viewed as a breeding ground for pests, but it prevents that function from occurring, shutting out the emergence of vectors! Furthermore, it blocks habitats and pathways for recent pest issues such as rats and weasels, preventing the emergence and transmission of pathogens, greatly enhancing hygiene. ~ Not only for public facilities but also for private facilities and places where people gather, it simultaneously solves landscape, barrier-free design, and hygiene issues! Tosk has numerous adoption records! Please contact us ~
