Stoupe Brow Landslip Repairs

The brief

With DSD Construction acting as Principal Contractor to NY Highways, scope of work included road repair works on Stoupe Brow, Ravenscar, within the Fylingdales Moor area of North Yorkshire – a rural, coastal road between Scarborough and Whitby that had recently suffered a landslide and was in need of urgent repair.

Our scope of work on this scheme included:

• Repairing the damaged road surface.

• Utilisation of the Gabion mattress structure and traditional highway resurfacing techniques to repair the road.
• Investigating a suspected blocked adjacent filter drain.
• Ditching and gripping the road providing access to a telecommunications mast.
• Planed out and relaid the carriageway using AC20 HDM Hardstone Binder, AC32 HDM Base and AC10 Surface Course.

Key quantities:

• AC20 HDM Hardstone Binder: 43 t
• 6F2 Capping: 880 t
• Gabion Stone: 640 t

Challenges & successes

To ensure the site was safe enough for work to commence, we had to clear a large quantity of material where the landslip had occured. This material was up to 3m deep and therefore required us to utilise equipment such as trench boxes to safely remove the material.

Receiving material, plant and equipment deliveries onto site proved a challenge due to the remote location of the project. To overcome this, the contract team produced a robust delivery schedule and agreed holding areas for material deliveries, helping to stop site from becoming congested.

Because there was a nearby property located at the far end of the site, it was crucial for us to adhere strictly to the programme’s critical path. This ensured that all necessary work was completed on schedule, allowing the property to maintain full access throughout the Christmas period without any disruptions.

Outputs & Benefits

Long-term Stability: This project will ensure long-term stability of the road as well as allowing water permeation to take place, reducing the risk of further damage and flooding in the future.
