The Canadian National Railway (CN Rail) wanted to build an additional 6-track extension at the Transcona yard in Winnipeg, Manitoba. Heavy rail cars were expected to pass over this extension area and CN Rail was looking for an economical, fast, environmentally friendly and technically sound solution for their track extension. The site had swampy conditions with wet and soft clay soils. In fact, when standing on the ground one would easily sink a minimum of 6 inches .The challenge was to design and construct a stable formation on the weak sub-grades which could serve as a satisfactory foundation for the rail tracks trafficked by heavy rail cars. Based on the nature of the sub-grade soils and the type of loading, Titan proposed a geosynthetics solution as the most suitable for this project.Their TE-BXC30 product, a heavy duty bi-axial geogrid composite, worked to seperate, filter and reinforce the subgrade.
