The Post Tension Plug is designed to create a 100% watertight line of defense at the tendon’s stressing end. The PT Plug is made of high-strength, non-shrink, non-metallic grout (8000 PSI compressive strength at 28 days that complies with ASTM C-1107) and is precasted to fit into the tendon’s stressing pocket after the pocket is abraded using the Post Tension Plug Reaming Tool. The Post Tension Plug's 1" of coverage ensures that the tendon iscutcut correctly and the grease cap is properly seated..

PLUG REAMING TOOL
The Reaming tool's diamond plated teeth are de-signed to roughen the inside pocket, remove any grease coating, and create a uniform circumfer-ence that emulates the shape of the Post Tension Plug. When used properly, the combination of the reaming tool, Post Tension Plug, and a high-strength, two-part, non-sag epoxy creates a water-tight seal that exceeds the capacities of traditional grouting in all measures.
ADVANTAGES
100% Watertight
Mininmum coverage requirement is achievedEnsures cables are cut correctlyRoughens surface for bonding purposesDecontaminates the pocket of grease and laitanceEliminates the chance of PT corrosion by rainfallBetter defense against corrosion in all climatesZero ShrinkageComplies with ACI and PTI StandardsFits flush to slab edge
