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.
Void Filling in Concrete Walls
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.
Electrical Control Pit Grouting
Performed the injection of concrete construction joints, leaking cracks and electrical conduits at a large gas-fired electrical power station using chemical grouts.
Leak Sealing in Tunnel Construction
Performed on time-critical sealing of leaking precast concrete tunnel segments using chemical grouts for a large municipal LRT system.
High-volume Water Stop Project
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
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.
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.
