Underground Tunnel Repair

This aged, underground tunnel had a large washout creating a 10’ x 20’ underground cavity. It was a challenging undertaking. The intricacies of this project involved the staged filling of the cavity void; constructing forms to hold the cavity fill and upper wall repair; repairing tunnel walls (upper and lower); and relining the 10’ x 200’ tunnel.
