Working on behalf of their client, network rail, Murphy’s bricked up 2 spans of the bridge to create a chamber underneath, which was to be filled through holes on the bridge deck. This enabled demolition of part of the bridge, without taking lengthy possessions of the Railway line which was to continue to operate under one of the spans.
When Murphy Group approached CEMEX for a suitable voidfill solution we proposed to use Porofoam, our lightweight foamed concrete product, which is designed specifically for each project by our UK Technical Department.
Porofoam is available in a range of densities and strengths and is manufactured using our proprietary CEMEX admixtures. The product can be mixed onsite by our foam production units or delivered in trucks premixed. For this project CEMEX delivered around 2000m3 of pre-mixed Porofoam over a 2 week period to meet the programmed demand.
