First, holes are bored specifically spaced apart according to an engineer’s drawings. On one side of the slab’s frame the cable extends through a hole. Notice the grease. The cable runs through a plastic sleeve that, after (post) concrete is poured into the form and has had time to harden, the cable is hydraulically pulled tight (tension), ie: post tension, meaning the concrete is stressed post pour.

The opposite end of the cable has a fixed wedge attached. During the tension process a technician adds a pinching device to prevent the cable from slipping back into the slab. After all the cables are pulled tight the steel is cut off with a torch and the opening in the side of the slab is puttied (filled) with mortar.

    The white plastic “chairs” in the video help space the steel in the center of the pad.
