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.
Leak sealing in Concrete Tunnel Liner
Engaged on a time-critical water stop project to seal active infiltrations through a concrete tunnel liner using chemical grouts.
Crack Injection around Industrial Pipe Penetrations
Performed precision drilling for crack injection work to seal leaking joints and cracks, using polyurethanes resin at a hydroelectric generation station.
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.
Leak Sealing in an Underground Chamber
Performed crack injection work to provide a solution based on chemical grouting for a leaking underground chamber.
Leak sealing in a Wastewater Municipal Project
Provided technical support for leak sealing work using Universal Resin at the Southeast Collector Trunk Sewer Project (SEC) for York and Durham Regions.
Leak Sealing in Pre-Cast Segments
Worked onsite to seal active infiltrations through pre-cast manhole segments, using Universal Resin, at Bay Adelaide Centre in Downtown Toronto.
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.
