Slope Remediation

HCM and RWH Engineering provided a design build solution to remediate a failing slope at a project located in Western Ontario.

Prior to HCM’s involvement, the site was excavated 7m into a silty clay at a 1:1 slope.  HCM was contacted after the slope began to fail and large movements were seen.  After RWH completed the design solution, HCM worked from a boom lift to install anchors with a TEI drill mounted on an excavator to stabilize the slope.  HCM applied meshed shotcrete directly to the face of the slope and tied in the system by post-tensioning the anchors.  Utilizing real-time engineering and quick execution, HCM was able to complete the installation without substantial ground loss, allowing for work onsite to be conducted safely.

HCM has applied shotcrete with tieback anchors as slope protection systems on many job sites with poor soils or tight sloping constraints. This project is an example of HCM’s and RWH’s ability to act quickly and adapt to changing site conditions to provide effective solutions.
