Air voids in the concrete - how foamed concrete is produced

Foam concrete is an extremely useful tool in the equipment of a modern construction project manager. Porous lightweight concrete production systems are used in a wide range of building and tunnelling projects around the world.

To improve and facilitate the production of environmentally friendly PLC (porous lightweight concrete) materials for construction above and below ground is the goal in future. High-quality foam concrete requires little CO² and energy to produce, making it a very ecologically-friendly option. 


  • easily-workable
  • low-density building material
  • economical
  • self-compacting
  • free flowing and pumpable and easy to place in inaccessible places
  • good thermal and acoustic properties
  • frost resistant

Cellular foam concrete can be produced in a variety of densities and strengths depending on the application required.

Foam concrete has many significant benefits due to its high air content (up to 90%), making the material ideal for filling voids in underground engineering works, trench reinstatement and tunnel repair. It is also particularly useful for its insulating properties making it perfect for thethermal and soundproofing insulation of floors and  flat roofs.
