Why Post-tensioning

The slab in your building will be thinner and span longer. PT flat slabs usually span above 10m with thickness of around 200 mm (depending on the category of use). That will significantly lower the total weight of the structure and allow for more economical foundations.

Dismantle formworks as early as 4-7 days after concrete has been poured and move it up to the next story. That’s possible thanks to the tendon force exerted on concrete, which helps bear its self-weight.

In PT slabs bonded reinforcement is used in addition to steel tendons to reduce cracking, improve ductility, and satisfy the current code requirements for concrete members. However, their amounts compared to RC slabs are significantly lower which minimizes the possibility of execution errors on site and makes the laying out process go smoother and faster.

In high-rise structures utilizing the PT slabs instead of RC ones usually results in more stories at the same total height of the structure. This is possible because PT slabs are thinner, and no column capitals are usually used in support zones making the PT slab soffit completely flat.

Make sure your offices and residential structures don’t set unnecessary limits. Clean and unobstructed ceilings of PT slabs will facilitate interior design allowing the architect to use the whole potential of your structure.

In properly designed PT slabs code deflection requirements are easy to achieve even with spanning above 10m.

Since post-tensioned slabs barely crack or not crack at all (depending on the design), their life spans tend to be longer than those of RC slabs. Therefore, the maintenance endeavours of PT slabs are sporadic and cost effective.
