PolySlab - Rib & Block Void Former Or Decking Blocks


  • PolySlab Blocks are expanded polystyrene decking blocks or void formers used in rib & block slab construction.
  • PolySlab Blocks are used instead of traditional ash blocks and they are placed between the concrete lintels to create a base on which the final concrete slab can be cast.


Benefits of using PolySlab Blocks instead of Ash Blocks


  • PolySlab Blocks are lightweight and easy to lift in multi-story building projects.
  • They significantly reduce they final weight of the concrete slab.
  • They increase the rate at which concrete slabs can be prepared and constructed.
  • Lightweight slabs reduce the amount of jacking supports required and the time that such supports need to remain in place.
  • This means that work can resume faster during the curing period of the concrete slab.
  • They increase the thermal and acoustic properties of the concrete slab.
