Thinner slabs, fewer beams, lower building height – here's how PT technology reduces cost and speeds up construction.
What is a PT slab?
High-tensile strands are placed in ducts within the slab and stressed after the concrete gains strength, putting the slab into compression.
Where the savings come from
- Reduced dead weight of the building – smaller columns and foundations.
- Reduced floor-to-floor height – lower overall building height and façade cost.
- Fewer beams and faster formwork cycles.
Bonded or unbonded?
Bonded systems use flat ducts that are grouted after stressing; unbonded systems use greased, encapsulated strands. Both are available from our PT component range.
