Multi-Flow

The Multi-Flow Drainage System is a fast acting, durable drain intended for the efficient removal of excess soil water. Multi-Flow is a closed-core geocomposite drain, made from HDPE, corrugated and perforated throughout. It is lightweight, strong and performs to meet the highest industry standards. Multi-Flow’s rugged design allows for shallow installation resulting in faster water entrance and reduced installation costs compared to traditional French drains. Its extensive surface area collects water quickly and its unobstructed flow channels carry that water away at an astonishing rate. Multi-Flow’s core is wrapped in a nonwoven geotextile fabric that prevents sand and soil from entering the flow channels, dramatically extending the life of the system.

Multi-Flow drain is manufactured in three sizes: 6-inch, 12-inch, and 18-inch. A full complement of “push-on” fittings and connectors is available in all three sizes, which make it fast and easy to create professional drainage installations. Applications for the Multi-Flow Drainage System include Athletic Fields, Golf Courses, Parks, Landscapes and Roadways.
