What is Post-Tensioning?

O.P.T. typically furnishes the following for all post-tension systems:

  • Engineering / Shop Drawings
  • Value Engineering from your Specifications
  • Materials
    • 1/2" DIA, 7 WIRE, 270 ksi, Low Relaxation Strand
    • Anchors
    • Pocket Formers
    • Chairs
    • Wedges
    • Nails
  • Specialty Products
  • Delivery to Jobsite
  • Stressing Operations
Parking Garages
Post-tension carries larger spans, requiring less shoring and re-shoring resulting in savings on concrete yield.
Slab-On-Ground Structure Foundations
Post-tensioned slabs-on-ground provide a cost-efficient, high-performance solution for problems associated with ground-supported residential foundations on shrink-swell soils. The compressive stresses resist the anticipated tension stresses induced by the soil movements, enhancing the performance over a non-prestressed foundation. Cost benefits are achieved by reductions in quantities of concrete, steel and excavations, which in turn reduce labor costs.
Parking Structures - Barrier Strand
Barrier Strand is a method for restraining vehicles in parking structures.  Strand offers an inexpensive and safe way to shield the impact of moving automobiles, protect pedestrians and maintain visibility. 
Slab-On-Ground Sport Courts

As stated by the Post-Tension Institute, the use of post-tension concrete in the construction of tennis, basketball, multi-purpose and other exposed and covered sport courts around the country has longer service life.
