Developing a technically challenging solution to overcome a landslide and a large sinkhole
This project was awarded to Stepnell after a large sinkhole had appeared outside ‘The Laurels Guesthouse’, as well as the occurrence of a landslip within the adjacent hillside, causing the Guesthouse to close and creating great concern for the surrounding residents.
In collaboration with the designers David Symonds Associates and Geo-environmental Engineers GIP Ltd, much strategic planning was required to access and carry out the works without causing a catastrophic failure of the hillside.
The works involved grouting of the sinkhole, use of specialist long reach excavators for access, CFA piling for initial hillside stabilisation, then the strategically phased construction of the ‘reinforced earth structure’, which was carried out to stabilise the hillside.
The whole of these works were carried out in a residential area where close relationships were paramount to the success of the project and were maintained throughout the duration of our works.
Due to our performance during this project and the relationships built with the residents, we were subsequently awarded the next phase of works which involved the complete refurbishment of the residents’ properties, constructing retaining walls, macadam access roads, as well as hard and soft landscaping.
