Maqs Hussain’s Projects

Cellular Grouting to Backfill Underground Casings

Greater Toronto Area, ON

A utility contractor required a grouting solution to backfill underground casings and control ground water migration into an excavation site.
Chemical Grouting for Underground Utilities

Guelph, ON

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.
Electrical Control Pit Grouting

Mississauga, ON

Performed the injection of concrete construction joints, leaking cracks and electrical conduits at a large gas-fired electrical power station using chemical grouts.
High-volume Water Stop Project

Toronto, ON

Water inflows through a caisson wall jeopardized a tunnel construction schedule. Multiurethanes designed and completed a chemical grouting program to stop the leaks and get the project back on schedule.
Leak Sealing in an Underground Chamber

Toronto, ON

Performed crack injection work to provide a solution based on chemical grouting for a leaking underground chamber.
Leak Sealing in Tunnel Construction

Edmonton, AB

Performed on time-critical sealing of leaking precast concrete tunnel segments using chemical grouts for a large municipal LRT system.
Soil Stabilization for High-rise Development Construction

Guelph, ON

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.
Void Filling in Concrete Walls

Toronto, ON

Provided cement grouting to fill voids and cracks in concrete walls to minimize water migration during the construction of a lakeside open-cut pedestrian tunnel.
