A permeable material that combines rigidity and flexibility! Ideal for sprayed concrete surfaces and more!
The "Moyai Drain Mat" is a drainage material made from polypropylene, which has the highest chemical resistance among polymer materials, and features a three-dimensional mesh structure with fused strands. Unlike typical three-dimensional mesh structures (such as loofah structures), it has randomly arranged tubular cavities (spiral pipe-like) in the in-plane water flow direction, allowing it to have multiple hollow sections in the water flow cross-section while still being a three-dimensional mesh. Furthermore, the Moyai Drain Mat Flexible Type maintains high pressure resistance while being able to bend freely, achieving a balance of rigidity and flexibility, making it possible to install stably even on uneven surfaces such as sprayed concrete. 【Features】 - Fully perforated linear mesh for water collection - Hollow spiral pipes for water flow - Extremely high pressure resistance - Eco Mark certified product (Certification number 07118006) - New Technology Information Provision System (NETIS) Registration number: CB-080007-V For more details, please contact us or download the catalog.
