The post-tensioning method is the best way to create stronger, more reliable concrete slabs. This method is a better way to construct a slab foundation to be more resistant to cracking and deflection. This stronger, thinner slab also saves money on concrete. To create a slab using this method, plastic sleeve-covered steel cables are laid in a grid running in both directions. Then concrete is poured and allowed to harden to 75% of its design strength. The cables are then post-tensioned or pulled by a hydraulic jack and the concrete is allowed to cure completely.
