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.
Leak Sealing in an Underground Chamber
Performed crack injection work to provide a solution based on chemical grouting for a leaking underground chamber.
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.
Chemical Injection in Mechanical Room
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.
Epoxy Injection in Canal Wall
A restoration contractor refurbishing the canal and lock gates found a joint that required to be sealed from infiltration of water. The joint was filled with epoxy, forming a rigid barrier, preventing the infiltration of water into the canal wall.
Innovative Water Cut Off Solution for a Hard Rock Tunnel
A large tunneling contractor found itself in a difficult situation with a large flowing water leak in a new rock tunnel 20 metres underground.
Cement Grouting to Fill Voids in Tunnel Cross Passage
Performed cement grout injection to fill voids and to stop water infiltration around the cross passage section in a tunnel.
Chemical Grouting to Stop Water Seepage into Utility Chamber
Engaged in water stop project to seal joints in precast underground utility chamber where infiltration was inevitable due to a high-water table.
Water Cut-off Operation in Tunnel Construction
Performed a water cut-off operation for a large utilities company to stop water inflows in a tunnel construction project, using polyurethane resins.
