Start handling permeable grating covers and permeable decorative lids Tosk!

Rainwater drainage suppression & barrier-free, plus hygiene issues!
Instead of draining through a steel grating like conventional grates, drainage occurs through the gaps in the gravel.
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, water flows through 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 solutions for rainwater suppression and the creation of livable communities!
