Corrugated Pipe is a single wall corrugated drainage pipe used for subsoil drainage applications. The pipe is not only strong but also lightweight. Ideal for drainage where flexibility, light weight and low cost are important. Made of high density flexible polyethylene construction it installs easily in uneven terrain. Pipe is wrapped in a filter sock to prevent debris build up in drain pipe. New, unused (just a little dust on outside)– pipe is leftover from a drainage job. $35.00
