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.
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.
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.
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.
Pressure Grouting for Railway Repair
Our technical team developed a solution to lift train track crossings on wood ties by pressure grouting under the tracks. This new approach was fast, reliable and surprised the utility contractor, who had been looking for this solution for a long time.
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.
Chemical Grouting for Masonry Restoration
Voids within a century old church tower required a low-density fill to prevent water infiltration from migrating within the masonry structure. Multiurethanes technical team safely filled the existing voids using durable chemical grout materials.
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.
