INSITU Contractors is located in Guelph, Ontario, Canada, which is about 100 kilometers west of Toronto. Our work takes us throughout Ontario and beyond to both coasts of Canada and into the U.S.A. INSITU CONTRACTORS was founded in 1994 and has grown steadily since, based on successful completion of hundreds of projects. The success of these projects is built on a sound technical understanding of groundwater conditions and many years experience providing practical solutions to groundwater issues. INSITU now houses its fleet of equipment in a 700 sq. metre maintenance facility and office in Guelph, Ontario.
