Foam Concrete Bridge Infill

GS Foam Concrete discuss the use of foam concrete for railway bridge infill.

When an old railway bridge becomes to costly to maintain the preferred method is to infill them thus meaning the bridge no longer has to have a maintenance period, this will save time and money over the years. GS foam concrete have been infilling bridges since 1984 and there are various ways to do the infilling as explained below.

Concrete Bridge Infill

Which ever method you use, shuttering must be erected either side of the bridge, we can either pump over the shuttering until we reach the top or we can pump or pour through core holes in the bridge, the problem with pouring through the core holes is the road may have to be closed while the works are being carried out, with the pumping method subject to site conditions we can pump from the side which will allow the road to remain open.

To ensure the bridge void is completely full the shuttering can either be erected higher then the bridge or we can top up through the core holes. Foam concrete bridge infill can only be poured 1 metre in height in any one shift so caution is recommended if more than 1 metre is required.
