Drain mat exclusively for tunnel backside drainage (B) with belts for installation on both sides!
The "Moyai Drain Mat" is a permeable material made from polypropylene, which excels in chemical resistance among polymer materials, featuring a three-dimensional mesh structure with fused strands. The newly formed structure through integral molding is a fully perforated strand mesh that combines the functions of water collection and water flow through a hollow spiral pipe, making it an ideal drainage material with high compressive strength. The "SWB Type (semi-permeable)" comes with belts for mounting on both sides, has a single-sided core material (without a permeable filter), and features a single-sided impermeable sheet. 【Features】 ■ Excellent chemical resistance ■ High compressive strength ■ Belts for mounting on both sides ■ Dedicated for tunnel back drainage (B) *For more details, please refer to the catalog or feel free to contact us.
