Abstract
An apparatus and method for reducing corrosion in post-tension construction is described. An anchor is engagable with a post-tension tendon and comprises an anchor base and sheath engaged with the anchor base, and a cap for sealing the portion of the tendon within the anchor. The sheath can include an extension having a contact end distal from the anchor base for contacting the tendon as the tendon is inserted through the extension and the anchor base aperture. The cap can extend completely through the anchor base for connection to the anchor base of a sheath or sheath extension attached to the base. A pocketformer is attachable to the sheath for generating a void in concrete.
