The Barneycraig Lead mine located in the North Pennines operated between 1760-1920. Due to mine tailings being deposited on the River West Allen it became the second worst river by Northumbria River Basin Management. A plan to improve the river meant the tailings needed to be capped to prevent rain water infiltration. Stabilisation of the dam was also required. ABG proposed Pozidrain 4SKL, this provided a rapidly installed single layer system without compriising on containment. Erosaweb GWX was used on the 1:2.5 slope for soil reinforcement and this was fixed with a non piercing fixing solution.
