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.
Loose fill surrounding a manhole structure required stabilization. Multiurethanes technicians injected Universal Resin through vertical injection pipes to stabilize the fill prior to cutting through the structure wall.
Applied a chemical grouting solution involving sodium silicate, delivered through sleeve pipes, after surface voids formed during a directional drilling project beneath an airport construction job site.
