Details are given of repairs made to the Harecastle tunnel, near Stoke-on-Trent, which carries the Trent and Mersey Canal for a distance of 1 3/4 miles. Falls of tunnel lining were thought to have been caused by the presence nearby of mine workings and the action of highly conresine mine water. Repairs consisted of stabilising the collapsed sections using stainless steel rock bolts and a lining of galvanised steel mesh held in place by stainless steel plates against the existing brick tunnel lining. So that concrete could be keyed to the base of the existing side walls, the water level had to be reduced and then shuttering and reinforcing set along each side to bring the side walls to a height above water level. The last stage was to place a permanent reinforced concrete tunnel lining, each pour being approximately 5 ft long. /TRRL/
