Foamed Concrete Applications

Foamed Concrete Applications

With a continued policy of research and development, ProPump Engineering have designed a range of mixes for an ever-widening range of applications. The specially designed mixes are formulated to enable our in-house designed and built equipment to manufacture and pump foamed concrete distances of over 200 linear metres.

Established 30 years ago, the award-winning Propump Engineering are considered one of the best specialists foamed concrete suppliers with expertise and experience to provide materials, specialist equipment and mix specifications on a global platform.

The ever developing range of mixes allow foamed concretes of various densities and strengths to be manufactured with densities ranging from below 400KG/m3 up to 1700KH/m3 and corresponding strengths from 0.5 MPA (N/mm2) up to 10 MPA (N/mm2). Daily production volumes have exceeded 1500m3 and regularly surpass 300m3 using the vehicular mounted in-line pump and foaming systems.

Generally, the application will influence the material specification, with a number of factors considered such as; strength, density, the required distance to pump, as well as local environmental factors such as material availability as well as CO2e requirements.

Most recently Propump Engineering have formulated new mixes for both low and high-density applications that have a much lower embodied CO2e content with no degradation of equivalent strength compared to their contemporary counterparts. These mixes are ongoing development and further underline Propumps commitment to the environment.

Typical applications that Propump Engineering have been asked to specify Foam Concrete for can be split into several groups: Pipes, Mass infill, Void fill, Ground reinstatement & stabilisation and Encapsulation.

Temporary mass infill application of foamed concrete
subways and road bridge strengthening applications of foamed concrete


  • Sewers
  • Decommissioned Gas Pipes
  • Drainage
  • Water Pipes

Mass infill

Any large volume to surface area ratio, including:

  • Large Tunnels
  • Mines
  • Shafts
  • Addits
  • Sink Holes
  • Dean Holes
  • Carparks
  • Road Slaps
  • Dykes
  • Basement Fills
  • Vault Fills

Voild fill

  • Typical includes closed pours such as olf coal vaults or basement voids where there may already be a partial fill or decaying brickwork
  • Bridge Arches
  • Bridge Strengthening
  • Caverns
  • Headings

Generally, void infills require undercuts or obscured voids to be filled and completely purge air our where a normal “concrete” would not successfully fill airgaps or cannot be vibrated

Ground reinstatement & stabilisation

  • Trenches
  • Footings
  • Embankments
  • Sink Holes
  • Temporary Works to Make Safe

Often these applications require the burial of new utilities or have a specification of low mass loading on an area.
