Runcorn Railway station built April 1869 is a very popular commute to London Euston station.
Upon site inspection the cuttings were found to be 12m high and the strata consisted of Sherwood Sandstone and Mercia mudstones. The site was susceptible to falling debris and a long term solution required.

The project

The first task was to remove the vegetation, this started in September 2015 with an eight month project completion date.
To prevent any potential issues with falling rock and subsequent dangers to passing trains rock fall protection materials were specified.

Solutions

Minova ATB (500 grade) 25mm dia galvanised anchor varying in lengths between 2m and 6m were installed with AM1000-1 Thixotropic Grout. The high early strengths of the grout (40N/mm2 in 24 hours) ensured rock fall netting could be installed without any delays.
As an additional measure Anti-theft caps were installed.

Result

More than 600 anchors were installed along with more than 12,000m2 of PVC Rock Netting. All works completed within programme timescale and budget. No recordable accidents or incidents.
