DEPTH OF BURIAL FOR PVC PIPETECHNICALBULLETINB uilding essentials for a better tomorrow JANUARY 2009 FLEXIBLE PIPE THEORYPVC pipes are classified as flexible pipes. They flex without breaking when loaded externally from soil weight and vehicular traffic. Rigid pipes, such as those made of concrete or clay, do not perceptibly flex when loaded and experience wall crushing when their load limit is reached. This mode of failure for rigid pipes has given rise to the terms crush strength and D-Load , but these terms do not apply to PVC a PVC pipe encounters external loading, its diameter will begin to deflect, meaning its sides will move outward and slightly downward. If the pipe is bur-ied in supportive soil, the stiffness of the soil will resist the deflection (see Figure 1).
