Trenchless Technology is an emerging area of construction involving innovative methods, materials, and equipment used for the installation of new and/or rehabilitation or replacement of existing underground infrastructure with minimal or no need for open cut excavation. This technology provides an alternative to traditional methods of open trenching construction, which is often associated with major disruptions to surface activities. Using trenchless construction methods, it is possible to complete complex underground infrastructure projects in congested urban areas in a safe, economical manner with minimal disruption to surface traffic, nearby businesses, or environmentally sensitive areas. The results of a survey of trenchless technology in Canada are presented. The survey, which was sent to 87 municipalities across Canada, provides an indication of current and future trends in the application of trenchless construction technologies in the municipal arena including: type and frequency of technologies employed; percentage of projects which employ trenchless technologies; expenditure for new construction and rehabilitation; and growth over the past five years.
