About this event

Jackfield is located 1km downstream of Ironbridge on the south side of the River Severn in the Ironbridge Gorge, Shropshire and is part of a UNESCO designated World Heritage Site. It is also the site of an historic landslip which has seriously affected residents, industry, rail and road transport since the early 1700’s.

There is only one road across the slip area into and out of the community and since 1982 the road has been overlaid with timber boards to allow the running area to deform with ongoing movements and to facilitate easier maintenance in the short term.

The primary objective of this technically demanding and complex project was to stabilise a 350m length of moving hillside which had the significant potential to experience a catastrophic landslip – which would dam the river and cause major upstream flooding. The total landslide volume was estimated to be in excess of 2 million cubic metres.

The main works involved the installation of around 2100 CFA piles each around 10m long in 9 crescent rows across the slip area of the hillside. These were designed to penetrate just past the slip plane which exists about 7m underground and to resist against further movement.

The potential landslip has now been effectively eliminated and the stabilisation has allowed for improvement of transport links back into the area with a new road and recreational footpaths and cycle ways.

The presentation will discuss a little of the history of the area and the delivery of the scheme from the Contractor’s perspective, including the challenges faced in maintaining a level of stability, temporary works and a couple of more unusual logistical difficulties.
