CPM Redi-Rock Modular Walling
Redi-Rock protects river embankment from erosion
When AMCO were asked to provide a scour protection by Network Rail, it was to an embankment where the River Hem flows adjacent to the main Paddington to Penzance railway line, in the village of Littlehempston, near Totnes in Devon.
During heavy and prolonged rainfall, the river rises significantly which has resulted in the erosing of the embankment. To reduce the risk of it failing, CPM's Redi-Rock modular walling was used to provide stability to the embankment, as the concrete blocks are quick and easy to install and are aesthetically pleasing to the surrounding area.
CPM's Redi-Rock concrete walling was deemed the best solution by AMCO as consent had to be obtained from the Environment Agency not to reduce the width of the river once the wall was complete and to ensure the prevention of silt being washed downstream, to overcome this straw bales and sedi mats were used and a temporary sand bag dam was placed around the area to allow the workforce to excavate and lay the wall foundations. Due to the location of the embankment, the one tonne concrete blocks were transported across farm land and lifted into place over the river with little disruption to the local livestock, who had access to the river to drink from.
