With ever increasing building costs, the requirement for rapid building and greater awareness of energy conservation as an important aspect of building design, expanded polystyrene (EPS) is becoming increasingly used in modern day construction.

"TASS Data Sheet"

"Dynamic, Inovative, Ecological and Professional."

The TASS uses the properties of EPS - thermal and sound insulation, lightweight, accuracy in moulding and cost competitiveness as the cornerstone of a patented multi storey floor slab system.


TASS is a combination of a moulded EPS block and cold rolled steel channel to form a 'rib and block'/coffer slab system for multi storey buildings.

The system comprises a priority high strength galvanised steel rib which supports the high density TASS EPS void formers.

The system is completed by the placement of reinforcing bars between the TASS blocks in both directions, reinforcing mesh above the blocks and concrete to fill the channels, encapsulate the rebar and mesh to form the structure of the floor slab.

The beams which are created by the concrete infill and rebar in the gaps between the TASS blocks creates a monolithic structure.

Some Benefits:

  • Lightweight
  • Quick and easy to install
  • Fully load bearing
  • Thermal and sound insulation
  • Fire performance
  • Long life
  • Cost competitive
  • Shorter supply lead times
  • Versatility

The TASS void formers are left in place and act both as a thermal and sound insulator.
