light concrete

Light concrete is a material that combines good insulating properties and allows the reduction of loads on the structures - it is lighter than standard concrete. Light series includes specially designed mixes manufactured with the use of the so-called ‘light aggregates’: styrofoam granulate (styro-concrete), leca (leca-concrete) or foaming agents (foam-concrete).


light series

  • foam-concrete (density in dry state 400-800 kg/m3)
  • styro-concrete (density in dry state 800-1400 kg/m3)
  • leca-concrete (density in dry state 1400-2000 kg/m3)


benefits and advantages of the solutions

  • allows load reduction on new and repaired structures (e.g. ceilings, flat roofs)
  • facilitates the leveling of surfaces (e.g. for floor bedding)
  • easily fills the spaces around pipes and protects systems against damage
  • improves the thermal insulation of floors
  • absorbs sounds better than standard concrete



  • inclined layers of flat roofs
  • relieving of repaired ceilings
  • filling-insulation and load-relief layer
  • thermal insulation leveling layer in floor heating systems


technical parameters

  • compressive strength 1 to 25 MPa *
  • density classes from 400 to 2000 kg/m3 *
  • consistency allowing easy laying and leveling of surfaces
  • possible feeding with a concrete pump - styro-concrete in density class D1.0 and D1.2
  • application with the use of an auger pump - foam-concrete
  • application with the use of a basket or directly from the concrete mixer - leca-concrete
  • maintenance as for regular concrete types


* Basic production and delivery of concrete is performed in accordance with: PN-EN 206+A2:2021-08 "Concrete. Requirements, properties, manufacturing and compliance" and PN-B-06265:2022-08 "Concrete -- Requirements, performance, production and conformity -- National supplement to PN-EN 206+A2:2021-08".
