A first in Quebec for The S.M. Group International Inc. geotechnical and eco-engineering specialists

The S.M. Group International Inc.’s geotechnical and eco-engineering specialists have been mandated by the MRC Les Moulins to provide technical assistance services for the stabilization of the Ouimet-Gascon stream in Terrebonne.

In its environmental policy, the City of Terrebonne’s objective is to improve the living conditions of its community, while remaining within the limits of the ecosystems carrying capacities, with an emphasis on ecological integrity, individual and generational equity, and economic efficiency.

When the citizens living adjacent to the Ouimet-Gascon stream expressed their concern about the deterioration of its embankments, the City of Terrebonne, under the governance of the MRC Les Moulins, called upon The S.M. Group International Inc.’s geotechnical and eco-engineering specialists. Further to the validation of the state of the stream and a stability analysis under current conditions, our team of experts were able to prioritize the sections that require stabilization, and then proceeded with the preparation of the stabilization plans and specifications, management of the call for tenders, work supervision and the MDDELCC’s authorization certificate request.

Our team of specialists pushed the limits of what was already done in Quebec by combining two stabilization techniques involving green gabion and rocker anchors.

The work consisted of stabilizing 6 m to 10 m high slopes on a stretch of 200 linear metres. The height of the slopes and the difficult access to the work site were the main issues to be considered for the stabilization concept, and all with the objective of achieving long-term sustainable work while respecting environmental standards.

In order to reach this goal, our team of specialists pushed the limits of what was already done in Quebec by combining two stabilization techniques involving green gabion and rocker anchors. A green gabion weight wall with an inclined facade was installed in the lower part of the slope in combination with a slope stabilization system using rocker anchors every 2.0 m and reaching a depth of 5.0 m. The whole of the stabilization structure will be completely vegetated, and the anchoring method makes it possible to preserve the mature trees already in place on the slopes benefiting from the stabilizing effect of their root network.

Through this project, The S.M. Group International Inc.’s geotechnical and eco-engineering specialists are once again demonstrating their ability to offer innovative, efficient and sustainable solutions that are up to the challenges of today’s world.
