Permanent Formwork
Permanent Formwork can either be reinforced (in the case of products such as Humeslab or Transfloor) or prestressed (in the case of solid reinforced panels). Both are usually topped.
Reinforced Permanent Formwork (Humeslab / Transfloor)
Reinforced permanent formwork panels (most commonly known as Humeslab or Transfloor) usually incorporate 55-75 mm thick precast concrete slabs with embedded reinforcement and lattice trusses. An in-situ concrete topping acts compositely with the precast panels. Polystyrene void-formers can be bonded to the top surface of the panel between the trusses in place of the in-situ concrete, resulting in a significant reduction in the weight of the slab and reducing the amount of in-situ concrete required. The system is frequently used in cantilevered balcony applications and imposes few restrictions on designers due to the flexibility in panel sizes.

Prestressed Permanent Formwork (solid reinforced slabs)
Solid reinforced slabs are reinforced wet-cast floor slabs (planks) that can be pretensioned depending on design needs. They are generally complemented with a structural in-situ topping to form a solid composite slab.
