Advanced American Construction Technology called Post Tension System in Bahria Town Rawalpindi for the first time. Innovative high strength concrete structures having four times more strength than conventional R.C.C Structures.

Salient Features of Post Tensioning

• Flat Slabs
• Great Fire Resistance
• High Strength
• Efficient Crack Control
• No Deflection
• Life time Structural Guarantee

The engineering-best friend of developers, architects, engineers and contractors – post-tensioning enables the construction and refurbishment of concrete structures; improving structural performance while also reducing construction time, costs, materials and environmental impact. But what is post-tensioning? Post-tensioning is a method of reinforcing concrete. High-strength steel tendons are positioned in ducts or sleeves before the concrete is placed. Once the concrete has gained strength, tension is then applied, pulling the tendons and anchoring them against the outer edges of the concrete, before service loads are applied.

The PT technique is a form of pre-stressing, which differs slightly from post-tensioning as steel tendons are tensioned before the concrete is placed. The tendons are stretched between strong bulkheads which withstand external forces and the concrete is poured around them.

Freyssinet’s founder Eugene Freyssinet successfully developed pre-stressed concrete in the 1930s, after recognizing that placing concrete under compression greatly increased its strength. He led the first application of post-tensioning on a marine terminal in France in 1933.

Post-tensioning uses

Post-tensioning is used extensively in bridges, floor slabs, silos and other forms of concrete construction.
