Our technical staff worked with a heavy civil contractor on an important rehabilitation project performing a variety of cement grouting work to replace the rail bridge that crosses Lansdowne Ave, south of Dundas Street West in Toronto.
A section of the bridge was removed on Friday night and the new section had to be installed and operational by Monday morning. Due to the urgent nature of the work, our grouting specialists used a fast setting grout to fill voids beneath pre-cast concrete sections and grouted anchors to hold the bridge structure.
Our portion of the grouting proceeded very well even though the weather conditions (rain and snow) were less than ideal for grouting work. All of the cement grouting operation was completed on schedule, with satisfactory results.
Performed microfine cement grouting and water-stop operations using polyurethane resins, and provided soil stabilization in cross passage tunnels along the road in a light rail transit (LRT) line construction project.
We provided soil stabilization services at the Eglinton Crosstown Project in Midtown Toronto.
The scope of work involved injecting cement grout around the tunnel liner to fill voids. Our solution involved a microfine cement grout mixture delivered through vertical injection pipes installed around the tunnel.
Microfine cement is able to penetrate very small openings such as soil pores and microscopic rock fissures, in order to improve strength and reduce permeability.

A general contractor required Multiurethanes’ assistance with the installation of Hydrotite CJ-3030 in precast concrete panels in the construction of a headwall, as part of the overflow system at an oil sands facility, north of Fort McMurray, AB.
Unlike a conventional, poured in place concrete headwall with engineered waterstop, this installation presented various challenges. This application required the Hydrotite to be installed within tight tolerances to allow the precast panels to line-up correctly. Additionally, in order for the Hydrotite to be effective, it had to firmly adhere to the precast concrete surface.
A team of six members from the general contractor’s personnel was trained by Multiurethanes’ engineers on how to install Hydrotite on the precast headwall panels. Following specific guidelines, the training provided for the client detailed the proper surface preparation, the appropriate positioning and the anchoring method for this Hydrotite installation.
Multiurethanes’ on-site technical support continued throughout all stages of the Hydrotite installation. After the completion of the Hydrotite application, the panels were successfully placed on a concrete leveling pad to form the required headwall.
A project to improve the electrical system in Toronto’s downtown core is currently undergoing and involves the construction of new cable chambers and concrete encased duct banks.
The contractor required a grouting solution to backfill underground casings and control ground water migration into the excavation site, adjacent to Lake Ontario’s shoreline.
Our experienced grouting specialists designed and successfully executed a cellular grouting program, using a mix of cement and foaming agent, suitable for this particular type of application and site conditions.
