Overview:
Masonry rehabilitation of Buckhorn Lock 31 on the Trent-Severn Waterway began October 17, 2016 and was completed May 24, 2018. Buckhorn Lock is a stone masonry lock, which was constructed in 1887. Water leakage was noted around the gates and the mortar joints were typically open. Many of the stone units were also spalled and fractured. The project consisted of 100% masonry repointing, grouting of the masonry wall core, and stone masonry repairs, including fracture repairs, Dutchman repairs and some stone replacement. Cofferdams were used to dewater the lock and allow for access to the rubble finish masonry walls located upstream and downstream of the lock. The work was completed over the winter months, since the lock is in use during the summer navigational period.
