WEBLESS CORRUGATED DUAL WALL FOUNDATION DRAIN AND RELATED METHOD
A webless corrugated dual wall foundation drain which is constructed as a hollow rectangular tubular member with an inner corrugated wall formed of HDPE and an integral outer smooth wall formed of the same material. The outer smooth wall of the foundation drain is attached to and integrally formed with the corrugations of the inner corrugated wall through a coextrusion process, thereby significantly enhancing the vertical beam stiffness of the foundation drain and eliminating the need for an internal supporting web.
