What Is
Post-Tensioning?

01

Stronger, Thinner Slabs

Post-tensioning uses high-strength steel tendons tensioned after concrete is poured, compressing the slab and dramatically increasing its load-carrying capacity — allowing thinner, longer spans than conventional reinforcement.

02

Reduced Material & Cost

By optimising structural efficiency, post-tensioned slabs use significantly less concrete and steel than traditional reinforced concrete — reducing material costs, self-weight, and construction time on commercial projects.

03

Ideal for Commercial Buildings

From multi-storey car parks and retail centres to high-rise residential and mixed-use developments, post-tensioning is the structural solution of choice for long-span, high-load commercial construction across Australia.
