A635 Manchester Road Retaining Wall Strengthening
The project works entailed strengthening and re construction works a 150m length of existing retaining wall supporting a section of highway six metres above to the River Tame.
A temporary cofferdam was established within the river to enable a disused tributary culvert to be cleaned and sealed-off with matching masonry before being infilled with a lightweight grout material. Scaffolding was also established within the cofferdam area to enable access to the existing stone wall for the installation of soil nails and pointing / pressure grouting of the existing masonry. All works were successfully carried out with close liasion with the Environment Agency.
The existing parapet wall was dismantled over the full 150m length of wall, with the existing wall being taken down to approximatley 1.0m below existing footpath level. Similar stone to the existing was specifically sourced to ensure the final aesthetics of the re constructed wall were in keeping with the local area.
The public footpath, kerbs and highway were all reinstated upon completion of the structural repairs to the retaining wall.
