A permeable material with both water collection and water conduction functions in a three-dimensional mesh structure.
The "Moyai Drain Mat" is a permeable material made from polypropylene, which has excellent chemical resistance among polymer materials, and features a three-dimensional mesh structure with fused strands. The newly formed structure through integral molding is a fully open-type strand mesh that combines the functions of water collection and water passage through a hollow spiral pipe, making it an ideal drainage material with high compressive strength. The "NB Type (Fully Permeable Type)" comes with a belt for one-sided installation and features a fully permeable filter (4mm PP mesh filter). 【Features】 ■ Dedicated for tunnel back drainage work (A) ■ Excellent chemical resistance ■ High compressive strength ■ Comes with a belt for one-sided installation *For more details, please refer to the catalog or feel free to contact us.
