The job entailed wall stabilisation works to the existing victorian masonry retaining wall completed on behalf of Rochdale MBC.

The wall is 144m in length and varies in height to a maximum of 5.5m.

The first phase of the works comprised of excavating to a depth of 2m below the top of the wall (to cellar level of the terraced houses) and backfilling with a lightweight Maxit Leca material whilst supporting existing gas services and installing new water main and surface water drainage.

Approximately 575 cubic metres of lightweight aggregate was installed.

The footpath was re-instated with tarmac and a new parapet guard rail was erected.

The second phase involved excavating the existing footpath in front of the retaining wall to a depth of 600mm and constructing a new reinforced concrete toe block to resist overturning moments.

A form liner (Reckli) with a random masonry pattern was used to match the existing retaining wall.

This new toe block became the footpath at an elevated level.

Once the toe block was constructed, scaffolding was erected and the top 500mm of the wall was re-built along with raking out and re-pointing the whole of the wall.
