Propump Engineering Ltd have a long standing reputation for providing a high quality service with reliable and consistent material supply to some of the world’s biggest construction projects.
Using nearly 30 years of experience in manufacturing foamed concretes, combined with proprietary Inline Foaming systems, we are confident we would be a strong supply partner.
Part of our success stems from our technical background, and we are more than capable of designing and completing, material testing for specific foamed concrete applications. These can be anything from monitoring high early strength and how it can be utilised for continual, timed pours (Fig 1). To improve maximum pour depth (Figs 2 & 3). Ultra-lightweight materials (Sub 500 Kg/m3) and how heat of hydration can effect material performance (both positively and negatively).
All testing is carried out using polystyrene cube moulds as recommended in the Concrete Society “Foamed Concrete Application & Specification” report. (Fig 4).
Foam Concrete poured into cones for testing and trials ensure our materials can be poured to depth, do not collapse and their light weight density is un changed 
Foamed concrete trials include “to depth” pouring where material is placed up to 3 metres deep, where it can be cured and then cut to record any compression throughout

Examples of possible applications
- General Void Fill
- Mass Void Fill
- TBM Support Material
- Addit Capping
- Changing Floor Levels
- Utility Encapsulation
- End of Life TBM Encapsulation
Foamed Concrete cube mould room, at combe down, somerset, the sheer volume of material manufactured required an onsite room for storing cube moulds, foamed concrete should be air cured and left in polystyrene moulds until crushing at either 28 or 90 days

Whilst most uses of Foamed Concrete can be generalised as void filling due to its non-structural properties, there are many applications where it can be designed to meet specific performance criteria. This ability has, in the past been invaluable for many technically challenging projects, including TBM breakthrough chambers on the Crossrail project (Fig 5 & 6) TBM launch pits at Hinkley point (Fig 7 & 8) and Ultra lightweight, mass infill Gerrards Cross (Fig 9).
At Hinkley point C, Foamed concrete was again used as a starting material for the TBM as it starts it journey under the Bristol channel

Propump manufacture and pump material in one operation, however at times, additional pumping operations are required, in this example the material needed to be place 30 metres below ground level and there was no option to use a fixed line.
