    construction, the use of post-tensioned foundations has expanded to support 4 and 5 story wood structures, steel and wood commercial buildings and concrete tilt ups. Post-tensioned slabs on ground have also been used for industrial floors where levelness is critical for sensitive in-dustrial machinery to function properly. Aside from supporting larger loads, the size of commercial foundations The general improvement in the factors of safety with post-tensioned slabs allows for a shortening of the slab construction cycle time. Further, the low level of load redistribution that occurs during the stripping operations makes post-tensioned slabs ideally suited to reshoring procedures. Provided the overall number of interconnected levels remains unaltered, it is possible to increase the

    What is Post-Tensioning. Post tensioning is a technique for reinforcing concrete. Post-tensioning tendons, which are prestressing steel cables inside plastic ducts or sleeves, are positioned in the forms before the concrete is placed. Jim Rogers, editor and publisher of Post Tension Magazine, says that until housing construction ground to a halt last year, about half of all post-tensioning work was slabs-on-ground for homes. Residential Concrete magazine had a good review of this in its September 2006 issue.
