Video shows the moment soil nail wall collapses in Coquitlam, Canada

The collapse of what appears to be a soil nail wall, used to retain a vertical excavation in Coquitlam, British Columbia, was caught on video on Wednesday, November 29.

Furthermore, the failure occurred on a site located at 500 Foster Avenue, where a 44-story tower is to be developed.

It has been reported that nobody was injured in the event, while repair work is expected to start immediately to ensure no further failures, according to Coquitlam’s general manager of planning and development, Andrew Merrilll.

A spokesperson for the developing company stated that all the required permits for the project had been attained, while work was being monitored by engineers.

It can be deducted from the video that cohesionless soil is present on site.

A vertical crack can originally be seen forming in the shotcrete wall, which is then followed by broader collapse on the wall and soil caving in.
