The Post Tension System is highly flexible and can be installed as a fence wall, security wall, or as a retaining wall. This system can stand alone or can have post tension reinforcement. This system maintains the strengths of the Segmental Systems and is able to incorporate parapet walls with the retaining walls. As a barrier wall this system can exceed 22 feet in height. This wall system also is versatile and able to meet architectural preferences by allowing the attachment of concrete, wood, or steel facing panels.
