Soil Stabilization Program using Sodium Silicate
Provided technical services to implement a soil stabilization program when loose sands were encountered during a directional drilling project beneath an active airport apron.
Cellular Grouting to Backfill Underground Casings
A utility contractor required a grouting solution to backfill underground casings and control ground water migration into an excavation site.
Grouting Program for Soil Stabilization
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.
Grouting Program for a Leaking Rock Shaft
Supported an extensive rehabilitation project for a leaking rock shaft at a hydroelectric dam.
Water cut-off in Pre-cast Segments
Worked onsite in a water cut-off operation to seal active inflows through pre-cast manhole segments.
Cement Grouting in LRT Construction Project
Performed microfine cement grouting and waterstop operations using polyurethane resins, and provided soil stabilization in cross passage tunnels along the road in a light rail transit (LRT) line construction project.
Cement Grouting to Fill Voids Behind a Tunnel Liner
Performed soil stabilization and microfine cement grout injection to fill voids around the tunnel liner at the Eglinton Crosstown Project in Downtown Toronto
Pressure Grouting for Railway Repair
Our technical team developed a solution to lift train track crossings on wood ties by pressure grouting under the tracks. This new approach was fast, reliable and surprised the utility contractor, who had been looking for this solution for a long time.
Soil Stabilization in Tunnel Construction Project
Provided soil stabilization for a complex tunnel project with several site restrictions including no drilling from surface and working in close proximity to sewer and water mains.
Chemical Grouting for Underground Utilities
After leaks in underground vaults damaged sensitive equipment, Multiurethanes used an experienced confined space entry team to perform strategic polyurethane injection work to stop the leaks.
