Abstract
Methods and devices for sealing and/or gripping concrete strengthening tendons. Some embodiments provide a method of forming a seal between an encapsulated anchor and a sheath of a tendon engaging the encapsulated anchor. Other embodiments provide a splice for forming a seal around a discontinuity in the sheath of a concrete tensioning tendon. Some embodiments provide a seal assembly for forming a seal between a tubular extension and a sheath of a tendon to protect an exposed portion of the tendon contained within the tubular extension. Some embodiments also provide a method of forming a fluid tight seal between tubular extension and a sheath of a tendon, while other embodiments provide a method of gripping the sheath of a tendon with a tubular extension to prevent the sheath from moving relative to the extension.
