Unbonded Post-Tensioning

Unbonded Monostrand Post-Tensioning Systems

Adaptable to a variety of structures, unbonded monostrand can be easily, rapidly, and economically installed. Applications for monostrand systems include elevated slabs, slab-on-grade, beams and transfer girders, joists, shear walls and mat foundations.

Our unbonded systems feature 0.5” and 0.6” diameter strands coated with a layer of specially formulated grease. The outer layer is seamless plastic extruded in one continuous operation to provide protection against corrosion. Each tendon is precisely coiled, cut, labeled, color-coded and delivered to the construction site. A wide variety of anchorage systems (see Product Information below) are available to meet design specifications.

Encapsulated unbonded monostrand systems are used in areas that are subject to corrosive conditions. Strands are protected at the anchorages using greased plastic sleeves and grease-filled end caps. Additionally, anchorage components are fully encapsulated in a high density polyethylene plastic covering and an optional encapsulated intermediate coupler anchorage system can be used to protect the strand at construction joints.
