What is Post-Tensioned Slab?
A post-tension slab is a slab of concrete that has been pre-stressed using a specific method to increase the strength of the concrete. Before a post-tension slab is poured, high-strength steel strands or cables are laid in a tight grid to help support and give strength to the slab once it has cured. The tendons are sheathed in plastic so that they do not directly touch the concrete. After the grid is laid then the concrete is poured and cured up to 75% at which point the “tensioning” of the cables is done.
Benefits of Post-Tensioned Slab
-Good for areas with expansive soils, such as Texas
-Economical because a smaller depth of concrete can be used to create the same result as regular slabs
-It reduces or eliminates shrinkage/cracking-therefore no joints, or fewer joints, are needed
-Cracks that do form are held tightly together
