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.
Void filling in a Water Treatment Plant
Provided technical services to fill voids and stabilize soil underneath a footing, during an expansion project at a wastewater treatment plant.
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.
Fill stabilization around a manhole
Loose fill surrounding a manhole structure required stabilization using crack injection to stabilize the fill prior to cutting through the structure wall.
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.
Void Filling under Factory Facility
Supported a cement grouting program required to fill underground voids encountered under a factory facility.
Soil Stabilization for High-rise Development Construction
A building restoration contractor experienced water leakage into the mechanical room. Polyurethane resin was injected to fill the holes, forming a semi-rigid foam barrier and preventing further water leakage.
Emergency Cement Grouting Operation to Stabilize a Retaining Wall
The City of Toronto required Multiurethanes' technical expertise for an emergency cement grouting project to stabilize an undermined retaining wall over a 50 m length.
