What is Post Tension Slab?

Post-tensioning is the slab reinforcement methodology of choice for elevated slab applications,slab-on-groundand more. This engineered solution creates cast-in-place, prestressed concrete by reinforcing the foundation after the concrete has been placed. In post-tension construction, tendons are placed prior to concrete placement, and once the concrete reaches a specific initial compressive strength, the tendons are stressed to a specified force and anchored. Post-tensioning’s external compressive force makes the concrete more resistant to the tensile stresses that would otherwise cause a foundation to pull apart and crack.
