Abstract: A porous pipe primarily of rubber and synthetic rubber reclaimed from rubber tires, ground to a relatively small granular size, with metal removed; such as, for example, would pass through a 30-mesh screen, process-mixed through a pipe extruder, with a much smaller binder mix of primarily polyethylene, along with vinyl, ABS binder, and a trace of attaclay. The resulting product is useful as a subsurface irrigation buried pipe, having high structural integrity effectively resisting soil-loading pipe collapse, and it even resists collapse from moderately large rocks in the soil, and yet has a high degree of flexibility along its length. A pipe is provided with cross sectional area of pipe wall more than twice the cross sectional area of the pipe opening.
