Trough Moulds - One Way Span

Trough Moulds are a reusable formwork system for constructing one-way spanning ribbed concrete floors, which can achieve greater spans and use less concrete when compared to traditional flat slabs. Traditionally manufactured from Filcor EPS (Expanded Polystyrene) with an external polypropylene skin, each Trough Mould is made to suit the individual requirements of the project and can be re-used multiple times. When struck, the Trough Mould, subject to specification, can achieve a good quality finish for exposed applications.


  • One way spanning ribbed slabs can achieve longer spans than traditional flat slabs
  • Reduces concrete volumes
  • Potential for reduction in slab thickness and weight
  • Good quality finish achievable for exposed soffits – Subject to specification
  • Lightweight and easy to fix and strike
  • Re-usable
  • Detailed take off service available
  • Fibreglass Options are available

For higher specification concrete finishes, a greater number of re-uses or for more complex profiles fibreglass trough moulds can also be supplied.


Used for the construction of one-way spanning ribbed concrete floors.
