Welland Canal


Rankin Construction has completed numerous projects for the St. Lawrence Seaway Management Corporation over the years. Some projects involved extensive concrete rehabilitation to the lock walls, including removal and replacement of the concrete facing. Removal of the concrete was completed by either blasting or mechanical means. Rankin Construction has performed projects for the Seaway annually and has always completed the work in time to meet the strict navigation season schedule of the Welland Canal system. Rehabilitation projects have required the removal and replacement of concrete surfaces on the 80-year-old lock walls.

Other projects successfully completed for the St. Lawrence Seaway include piling, slope stabilization, mass earth excavation, and dredging. Rankin Construction has performed under extreme winter conditions that involved crews working in 24-hour shifts in order to meet the tight timeframe.
