Reinforcement For Slabs on Ground

The Nestle Distribution Center developed by LaCasa de Pietra in Santiago, Chile, is approximately 400,000 square feet of post-tension reinforced floor. Each placement is 13x75 feet. Five placements were tensioned at one time in both directions. These were tensioned to other panel groups until the entire floor was stitched together with PT tendons.

Light reinforcing continued through contraction joints for load transfer and chaired up just before concrete placement.

Heavy continuous reinforcing to eliminate contraction joints and only have tight cracks.

A 127x60 foot warehouse floor slab 6 inches thick with HVSF and no joints or cracks after three and a half years.

A 340x125-foot distribution center floor slab with two-way bundled PT tendons and no joints or cracks after eight years. Note void former offset so that bollard will be centered after 1 inch plus of slab movement.

PT jack and tensioned tendon with total elongation of 27 inches. Note white paint marking partial elongation in staged jacking.
