Engineering longer spans with less material
Post-tensioned structures put concrete to work before the load ever arrives — a controlled prestress that lets the same material span further, sit thinner and crack less, transforming what a floor plate or a transfer structure can achieve.
By tensioning high-strength tendons against the hardened concrete, we hold the member in permanent compression and balance much of the gravity load before it can develop tension. The result is longer spans, shallower sections, leaner reinforcement and far tighter control of deflection and cracking — efficiency engineered into prestressed concrete from the outset.
From PT slabs to complete prestressed structures
PT Slab Design
Bonded and unbonded post-tensioned slabs — flat plate, banded and hybrid forms — designed for clean soffits, minimum depth and tight crack control.
Transfer Structures
Post-tensioned transfer beams and plates carry very high concentrated loads across open space below while keeping deflection and depth in check.
Long-Span Floors
Prestress keeps depths economical and deflections controlled, opening large, uninterrupted floors free of forests of columns or deep beams.
Parking Structures
Long, column-light bays with crack control engineered to protect an inherently exposed deck from water and chloride ingress over its life.
Commercial Buildings
Open, adaptable floor plates with generous clear spans and minimal depth that maximise lettable space and floor-to-floor efficiency.
Industrial Buildings
Wide-span, heavily loaded floors and supporting structures that stay efficient while keeping member sizes and material quantities disciplined.
Where post-tensioning earns its place
Slabs & Floors
PT slabs and long-span floors deliver column-free, slender plates with flat, durable surfaces and the depth economy conventional concrete cannot match.
Transfer Structures
Post-tensioned transfer beams and plates redistribute heavy column loads over lobbies, retail floors and basements within a controllable depth.
Parking & Industrial
Long, manoeuvrable bays and wide, heavily loaded industrial floors where crack control and durability protect the structure in demanding service.
Tendon profiling, honest accounting of prestress losses and long-term durability are engineered as primary concerns — so each structure achieves its efficiency without compromising safety, serviceability or constructability.
