The Advantage of Post-Tensioning in Buildings
Post-tensioning systems offer significant advantages over conventional reinforced concrete in building projects. Reduced slab thickness, fewer columns and wider spans deliver both architectural flexibility and cost savings.
ASZ GRUP installs post-tensioned slab and beam systems on long-span projects such as shopping centres, car parks, airport terminals, exhibition halls and high-rise buildings.
Why Post-Tension Buildings?
Traditional reinforced concrete slabs require thicker sections and more columns for long spans. Post-tensioning applies prestress to concrete, enabling the same span with much thinner sections — reducing floor-to-floor height, overall building height and material consumption.
- 25–35% reduction in slab thickness — Thinner slabs reduce floor-to-floor height and overall building cost.
- Significant reduction in column count — Long spans with fewer columns increase architectural flexibility.
- Concrete and steel savings — Economical, sustainable projects with reduced material consumption.
- Fast formwork cycling — Early stressing shortens formwork cycles and accelerates the construction programme.
Economical Solutions
Savings in total project cost through reduced material quantities and shorter construction time.
Thin Slabs
Post-tensioning reduces slab thickness, floor height and building weight.
Long Spans
Flexible, functional spaces with column-free spans of 15–20 metres.
Fast Installation
Time savings on the construction programme through early stressing and fast formwork turnover.
Application Areas
Building post-tensioning systems are preferred for many structure types requiring long spans and high performance:
- Shopping centres and commercial buildings
- Multi-storey car parks
- Airport terminal buildings
- Exhibition and convention centres
- High-rise residential and office projects
- Industrial facilities and warehouse structures
