A general contractor in western Manitoba required grouting expertise to stabilize an extra-large construction joint (250 m long) on a dam rehabilitation project. The concrete had started to deteriorate, creating small voids in the joint.
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.

Assisted an infrastructure contractor with a cellular grouting operation to backfill relined culverts along Highway 407. A mix of cement slurry and foam agent was successfully placed using low-pressure grouting techniques to fill the annular space along the pipe.
Our skilled technicians assisted a utility contractor with a cellular grouting operation to backfill underground casings, as part of the project to upgrade the Toronto’s electrical system. A mix of cement slurry and foaming agent was successfully used to fill the annular space along the pipes in the electrical installation.
