Introducing a fully permeable drainage material with both excellent drainage capacity and high pressure resistance! Featuring a three-dimensional mesh spiral structure.
The "Moyai Drain" is a drainage material with a three-dimensional mesh structure, featuring a spiral pipe arrangement that directs water flow internally. The "Standard" type is a rigid, plate-like structure, making it suitable for installation in flat areas for backfill drainage behind retaining walls, bridge abutments, and concrete structures. The "N type" comes in two varieties: "Standard" and "Flexible," allowing for selection based on application. Both types possess excellent drainage collection capabilities and high pressure resistance due to their three-dimensional mesh spiral structure, making them ideal drainage materials. 【Standard Type Features】 ■ Fully permeable drainage material ■ High rigidity plate-like structure ■ Suitable for installation in flat areas for backfill drainage ■ Three-dimensional mesh spiral structure ■ Combines excellent drainage collection capabilities with high pressure resistance *For more details, please refer to the PDF document or feel free to contact us.
