Cement grouting for Bridge Rehabilitation

Cement Grouting for Bridge Rehabilitation

Location: Toronto, ON
Sector: Infrastructure
Category: Cement Grouting


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.

Water cutoff in a sewer rehabilitation project

Leak Sealing in Sewer Rehabilitation Project

Location: Markham, ON
Sector: Utilities
Category: Cement Grouting, Water Cut-off


We provided a specialized water cut-off solution for a municipal sewer maintenance project. The project required grouting from surface to repair leaks in a large diameter sewer pipe.

Our solution involved pumping a fast-curing cement plus sodium silicate grout mixture delivered through vertical injection pipes installed around the sewer.

This work required a customized grout plant with multiple pumps and flow meters.
