A major landslip saw the movement of 326,000 tonnes of rock and soil along 160 linear metres of embankment, resulting in the closure of the line between Leamington Spa and Banbury. Following emergency meetings with Network Rail, Murphy devised a plan to remove the landslide and re-build the entire slope.
We removed 326,000 tonnes of earth from the slip area and landscaped the embankment, to create two slopes on a 1:2 gradient, new 30m and 4m horizontal berms, a 1:3 slope and counterfort drains.
In order to minimise disruption to the public, the works needed to be completed within a challenging ’40 days and 40 nights’ timescale. The site is one of special scientific interest (SSSI) because of its butterflies, bats and badgers, and is also a habitat for great crested newts. The project meant dealing with difficult mudstone soil conditions, as it was brittle in dry weather and loose in wet weather.
