Foamed concrete is usually a pumpable, free flowing material, it requires no compacting and can be poured in layers of up to 1 metre in depth. Propump place foamed concretes that will search and encapsulate with ease. Foamed Concretes are, to an extent, self-levelling and will freely flow upwards of 30 metres. The characteristics of each different mix design can be modified to suit the application.


  • Pumpable
  • Reduced labour / manpower to place
  • light weight
  • self consolidating
  • no vibration required
  • insulating
  • easily machinable / re-excavatable

Strength and density

Unrivalled range of mixes to achieve designed strengths and plastic densities. Propump have a large stable of tried and tested mix designs across densities. At propump we pride ourselves in quality and service. New mixes can be designed, trialled and tested for use if so required.
