30mm Drainage Cell

Brief Introduction of Composite Drainage Cell
Drainage Board adopt high-density polyethylene as raw material,using highpressure injection molding process to suppress a hole-shaped lump, with three-dimensional space and certain support height. It is popularly applied in roof greening,subway tunnels,water reservoir seepage,vertical green and many other areas.
