Post tension in construction is a cost effective, reliable and quality triggered process. The use of post-tensioned reinforcing can result in thinner concrete sections, longer spans between support, stiffer walls to resist lateral loads, and stiffer foundations to resist the effects of shrinking and swelling soils. The additional advantage of putting the concrete into compression can be used to construct slabs and walls they have fewer visible cracks the can allow the passage of moisture and termites the core business of ost tension work in maps is concentrated in buildings and bridges.post tensioning process involves various stages of work, staring from the design stage based on the requirments.followed by manufacturing and then to the final stage of the actual executing of work in the site.Sucess of our projects is due to intricate care and precision that is considered in all the stages of our wok

Post tensioning

Post tensioning applications is seen in almost all facets of construction. The method of reinforcing concrete with high strength steel strands is called as post tensioning. Concrete is very strong in compression but weak in tension. Therefore the slight deflection will cause tension face to elongate and eventually leading to a crack.post tensioned concrete slab limits the crack widths. It can be designed to have minimal deflection and cracking even under full load.

The concept of post tension is easy to explain. Imagine a series of wooden blocks with holes drilled through them, into which a rubber band is threaded. If one holds the ends of the rubber band, the blocks will sag.post-tensioning can be demonstrated by placing wing nuts on either end of the rubber band so that the blocks are pushed tightly together. If one holds the wing nuts after winding, the blocks will remain straight. The tightened rubber band is comparable to a post-tensioning tendon that has been stretched by hydraulic jacks and is held in place by wedge-type anchoring devices.

Design

Design is one of the most important aspects of Post Tensioning. Design and analysis forms the firwst step for new post-tensioned structure. Factors that affect the selection of structural system and methods to optimize the design are analysed. Code provisions relating to the design of post-tensioned structure are also taken into consideration. It is a good design that ensures optimum structure that offer maximum strength at minimum cost. The design engineers at MEPS have decades of experience between them and can be counted among best in the industry in the region.
