Clay offers many critical advantages in terms of corrosion resistance, structural integrity and environmental impact that make it the best investment over the life of the installation.

Because corrosion is one of the principal causes of pipe failure, corrosion resistance is one of the most important factors in the selection of sanitary sewer pipe, particularly in the industrial and commercial settings. Sanitary sewers are subjected to the discharge of industrial wastes and solvents. These fluids can attack both cement-bonded pipe and flexible pipe, causing deterioration of the former and cracking or softening of the latter.

The vitrified clay pipe is the only sewer pipe material proven over centuries of use to be resistant to attack by industrial wastes and solvents or aggressive soils. It only reacts to two industrial compounds: hydrofluoric acid and hydroxide. Therefore, it will not rust, shrink, elongate, bend, deflect, erode, oxidize or deteriorate like other pipe materials may.

Clay is chemically inert and is the most chemically resistant sewer pipe material available. Clay pipe has no negative impact on the environment, because it:
