A significant slip occurred on this old quarried face overlooking this manufacturing site. Concerns were raised that there was a high likelihood of further slips occurring on this now loose and destabilised slope.
Given the approaching onset of the winter months and wet weather, further concerns were raised about the risks of destabilising the slope further by stripping the entire face of vegetation prior to the works taking place.
CAN’s solution was to undertake the work in vertical strips to help alleviate the aforementioned risk. This however did create difficulties in setting out, as this would normally be done across the whole slope in one go, ensuring neat and precise layout of the soil nails.
The steep and high face required a combination of approaches, utilising drill booms attached to long reach excavators and A-frame rigs for the upper reaches of the slope.
All works had to be carried out working alongside a local ecologist as the site had the potential to be home to newts, dormice and bats.
CAN successfully stabilised the slope allowing normal operations to return to the site. The 959 soil nails were neatly and uniformly laid out, with 2351m2 of Maccaferri PVC coated rock fall netting and Enkamat erosion control matting.
