Concrete Consolidation

The quality of concrete can be significantly improved by vibration by reducing the volume of voids, air pockets, and entrapped air in a fresh cementitious mixture.

Fresh concrete does not compact by itself because the poor fluidity cannot surpass internal friction. Only vibration can overcome this force.

Vibration Favours

  • The surfacing of the air trapped in the concrete
  • The displacement of aggregates, aligning them to one another, with consequent reduction of cavities, conferring them high density and perfect homogeneity
  • The adhesion of the concrete to the bars of the reinforcement armatures or to any internal structural inserts, as well as to the basic anchorages.


  • High mechanical resistance.
  • Low porosity and thus low permeability to water and to aggressive substances contained therein.
  • Absence of cracks within the concrete, in the proximity of the reinforcement armatures’ bars.
  • Complete filling of the formwork.
  • Increase in the life cycle of the concrete.
  • High aesthetic result.
