Dawlish Road Failure, Devon
Red Rock undertook the stabilisation design of a section of failing slope affecting a public road.
The site comprised a 15m long section of a steep slope bewlow a public road, between 3.5m to 5.5m in height, descending to a private lane at the rear of a residential property. The failure was attributed to a burst water pipe.
The stabilisation of the embankment required 3-5 rows of 2-4m long soil nails to Eurocode requirements and geo composite mesh of high tensile wire and erosion matting to reduce further spalling of the Head deposits. The design accounted for the presence of many underground services which needed to be avoided during the installation of the anchors.
The stabilisation works were undertaken by Vertical Technology Limited.
