Tosk (Permeable Grating Cover / Permeable Decorative Lid)

Urban water disasters: Suppressing rainwater, addressing internal flooding and inundation, and proposing livable streetscapes. Tosk solves multiple underlying 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 garbage while allowing 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 measures, landscape improvement, pest control, barrier-free access, anti-slip measures, 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 while debris is prevented. 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! Furthermore, the natural stone finish enhances the landscape. 3. Safety and high durability. Contributes to barrier-free access. 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 seen as a breeding ground for pests, but it prevents this function from occurring, shutting out the emergence of vectors! Additionally, it blocks habitats and pathways for recent pest issues like 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, solving landscape, barrier-free access, and hygiene issues all at once! Tosk has numerous adoption records! Please contact us ~
