LRT Slope Protection at Retaining Wall

HC Matcon (HCM) and RWH Engineering (RWH) reacted quickly after being contacted to provide a design-build solution for a slope failure that occurred during the excavation for a new retaining wall at the Eglinton LRT project. The 14m (45’) high slope was approximately halfway excavated for a permanent block retaining wall when it a sudden slip failure occurred creating concern for the adjacent properties. RWH designed a slope retention system with soil nails and shotcrete facing to remediate the slope and allow for continued excavation. Using a TEI drill mounted on an excavator, HCM was able to reach the top of slope to install soil nails.  Shotcrete was applied by a nozzleman in an elevated work platform. Once the exposed portion of the failed slope was stabilized, excavation was able to resume and HCM continued installing additional lifts of anchors and shotcrete to the base of the finished slope for a total protected area of 1250m2 (13,500 SF).

HCM and RWH provided an efficient solution, adapting the slope protection design to assist with the durability of the permanent retaining wall. Real-time design changes were made onsite to accommodate additional area required after installation had already commenced, enabling the original retaining wall construction to resume as fast as possible.
