Old Lane, Little Hulton, Grouting Works

A Coal Mining Risk Assessment identified the potential presence of shallow coal mineworkings beneath the site, associated with two southerly dipping coal seams.

The subsequent site investigation proved an area of workings with suspected collapsed workings further to the north, towards the outcrop position.

A grouting specification was developed which encompassed an element of trial grouting in areas of suspected collapsed workings and treatment of voided strata.

Our staff supervised the treatment of the programme of ground stabilisation, which was undertaken over a three-week period.
