Artesian Water Control in Sampling well
Engaged in a chemical grout application based on polyurethane resin injection, as the appropriate water cut-off solution for a sampling well that intersected a high volume artesian water flow.
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.
Culvert Repair Project
Provided technical leadership to perform chemical pressure grouting in a major culvert repair project requiring crack sealing in more than 600 linear meters under Highway 174.
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.
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.
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.
Grouting Program for a Leaking Rock Shaft
Supported an extensive rehabilitation project for a leaking rock shaft at a hydroelectric dam.
