Scout Road Landslip

Scout Road Landslip

Deep soil mixing works have recently been completed at this site in Mytholmroyd, West Yorkshire to remediate a 100m-high steep natural slope. At the top of the slope there is a former quarry which is now used as a landfill for disposal of controlled waste. As a result of a recent failure, landslip detritus containing asbestos displaced halfway down the slope, representing an unacceptable risk to nearby residential properties and a primary school.

Scout Road Landslip

Our Role

Ayesa designed a soil stabilisation solution that increases the strength of the waste deposits and binds contaminants in order to reduce the likelihood and consequences of future landslips. The stabilisation was extended through the overburden and keys into competent bedrock, using a specialised ‘Allu’ mixing tool. Works were undertaken in a bottom-up tiered sequence, with a temporary kingpost wall positioned mid-slope to facilitate safe access for construction plant. The use of carefully supervised field trials and verification testing proved the strength characteristics of the stabilised soils.
