Hollowcore: Prestressed floor slab with longitudinal voids that cut weight without losing span.
Demoulding: Releasing a cured element from its form — the point where cycle time is won or lost.
Haunch: The thickened corner between a culvert's wall and slab, where shear is highest.
Grade ring: A shallow ring stacked under a cover to bring a structure up to finished road level.
Prestressing: Tensioning strand before the pour so the element resists tension once released.
Self-consolidating: A mix fluid enough to fill congested reinforcement without vibration.
Wet cast: Higher-slump concrete cast in a form and left to cure before stripping.
Dry cast: Zero-slump concrete compacted and stripped immediately, used for pipe and rings.
