The City of Toronto required MME Multiurethanes‘ technical expertise for an emergency cement grouting project to stabilize an undermined retaining wall over a 50 m length.

One of the biggest challenges was accessing the work area through the dense bush over a small muddy path. Once there, our grouting technicians drilled steel grout pipes into the bottom of the retaining wall. The grouting equipment was transported to the site by using a loader and consisted of a portable grout mixing and pumping unit with an ancillary water supply.

This emergency project was completed within four days and required 500 bags of high-performance non-shrink grout. A solid foundation was created to permanently stabilize the retaining wall and adjacent embankment.
