GIP were commissioned by Telford & Wrekin Council, under the term contract, to carry out ground investigation works to provide information to their designers to enable the design of a remediation strategy for the Jackfield Landslip.
In 1952 a major landslip occurred at the village of Jackfield in Shropshire, within the River Severn Valley down river from Ironbridge. The landslip destroyed a number of properties and caused a major dislocation in the railway and road. Since that time there has been continual movement of the landslip which had resulted in ongoing works to maintain the roads and services.
In 2013 Telford & Wrekin Council (TWC) were granted funding of £17.6m to stabilise the landslip.
GIP were involved during the investigation stages undertaking many boreholes, installing geotechnical monitoring equipment, undertaking geo-technical and geo-environmental testing.
Many of the positions were in locations that were not straight forward to access, due to working in fields, woodland and on slopes, we were able to work closely with TWC to create access roads and use alternative pieces of plant / equipment in order to achieve their drilling location requirements.
The information GIP provided to TWC enabled their designers to produce a design comprising of steel and concrete piles of 600mm diameter, up to 14m length, that were sunk into the ground and rock, in nine rows across the hillside. In order to allow this design to be successful GIP were commissioned to undertake drilling and grouting of past underground mining.
We were able to undertake all the requested fieldworks and mining treatment works within the time frames given, in what was a difficult working environments.
