KNTS Super is a corrugated tube, used for soil drainage and conducting water, produced by extrusion of HDPE (high density polyethylene),  designed to resist the mechanical tensile strength and the chemicals contained in the drained fluid. It allows great agility in the installation process due to its light weigth.
