Abstract
An apparatus and method for reducing corrosion in post-tension construction is described. An anchor base having an aperture with at two continuously opening surfaces is used with a post-tension tendon. A sheath surrounds the anchor and includes a cylindrical extension having a contact end distal from the anchor base for contacting the tendon as the tendon is inserted through the cylindrical extension and the anchor base aperture. The method positions an anchor base in a selected location so that a tendon end can be inserted into the anchor base to engaged the contact end distal from the anchor base. The tendon is threaded through the anchor base until a selected length extends through the base. The tendon is tensioned, a segment of the tendon sleeve is removed proximate to the anchor base, and a wedge is anchored between the tendon and the anchor base.
