What Is Epoxy Post Tensioned Truncation?
Epoxy truncation or wedging is required when a penetration or void is getting cut out of an existing post tensioned slab.
This is most often during the incorporation of lifts, stairs, travelators and similar services.
How Post Tension Truncation Works
Once the proposed cut-out lines have been marked on the slab, concrete scanning for the tendons occurs, then the wedge is centred over the tendon. The wedge shape is cut into its perimeter at a depth of 10 mm, so that the concrete inside the wedge area can now be broken out. Once depth is achieved by reaching all around the tendon, any exposed reinforcement is mechanically cleaned, the tendon sleeve is cut back, the sleeve grout is removed, and the steel strands are cleaned and treated.
The wedge is then ready to be cast with epoxy grout. So when the slab is cut, the wedge is sufficiently bonded to the steel strands in case of any movement in the tendon.
