Philadelphia Post-tensioning Co. (PPL) provide services in the construction field by increasing the loading capacity of concrete elements like beams, slabs, bridges, silos, slabs on ground etc. This is done by exploiting the force of high tensile steel to make concrete in continuous compression. This will help avoid any cracks to appear in the concrete. The flexibility of the strands allows the duct to be profiled through theoretically cracked area of the structural element and the tension in the concrete will be reverted into compression. This Technology will help us produce structures with economical long, shallow and deflection controlled structures. Buildings will be more earthquake resistant.
