Using the Century Water Barrier as Bamboo barrier is a very effective way to delay the growth and spread of the invasive Bamboo species. The flat smooth surface of the barrier acts as a wall or root stop which directs the rhizome and preventing rampant growth. Since the rhizome cannot penetrate the barrier it will be directed to grow downward along the surface of the barrier. This action will prevent unwanted spread and growth while containing the Bamboo species.
