Post Tensioning Applications



Many of the concrete tennis court in the United States are now being post-tensioned. Contractors that specialize in tennis court construction have found that post-tensioning minimize cracking, eliminate expansion joints and decrease water penetration. The post-tensioned slab compares favorable in cost with a reinforced slab and the time of installation reduced. We ship all of the necessary post-tensioning material to contractors throughout the country.




Post-tensioned slabs for single-family homes are common in parts of the U.S. where expansion or compressible soils occur. In some towns, 95%of all new slabs are post-tensioned. It has been found that where conditions exist that requires and grade beams to be reinforced with No.5 and No.4 rebars, respectively, and were 6x6x6x6 mesh is required; a post-tensioned slab is a more economical and structural superior alternate. In the areas where structural piling is required, a post-tensioned design is generally more economical.



The foundation slabs for apartments and condominiums require conventional reinforcement than single-family homes. It has been found that heavier the conventional design, the more economical the post-tensioning alternate becomes.




An increasing number or contractors and owners are recognizing the economic and structural advantages of using post-tensioning cables in warehouse slabs. Typically, a 6” thick slab, conventionally reinforced with 6x12x0-1 and No.5 rods, can be replaced with a 4 to 4 ½” post-tensioned slab that is structurally superior for crack control and load carrying capability. The total savings with post-tensioning, considering the steel reduction and concrete reduction, makes the post-tensioning alternate design very attractive economically. A post-tensioned slab is very effective in the transferring the steel column loads into the beams and slab, thus reducing the possibility of shear failure near the columns.
