Engineered Grouting Solutions.
Underground Problems Solved.
From massive infrastructure stabilization to precision groundwater control, SG Services delivers specialized geotechnical and structural grouting for Canada’s toughest environments.
Trusted by Canada’s leading civil,
mining, and infrastructure teams.
Specialty Grouting Services
Targeted geotechnical solutions to stabilize structures, control water, and mitigate risk.
Groundwater Control & Mitigation
Stop high-volume inflows and manage water migration. We deploy advanced chemical and cementitious grouting to seal fractures and secure your excavation.
Soil Stabilization & Ground Improvement
Enhance load-bearing capacity and mitigate settlement. Our precision ground injection techniques reinforce weak soils prior to or during construction.
Annular Space Grouting
Complete, void-free encasement for slipline and tunnel liners. We place purpose-designed low-density cellular concrete (LDCC) and sanded mixes for long-term structural integrity.
Void Filling & Structural Support
Remediate sub-surface washouts and stabilize sinking foundations. We safely fill subterranean voids to prevent catastrophic structural failure.
Pipe Abandonment & Decommissioning
Safe, compliant closure of redundant utility lines, culverts, and pipelines. We utilize highly flowable grouts to achieve complete fill over long distances.
Built for Demanding Industries
Mining Grouting Services
High-volume water curtain grouting, shaft sinking support, and underground rehabilitation. We mitigate water inflows and stabilize rock masses to ensure safe, continuous mining operations.
Tunnel & Shaft Grouting
Specialized pre-excavation grouting, TBM break-in/break-out zones, and backfill grouting. We secure complex underground pathways, manage hydrostatic pressure, and prevent settlement.
Civil Infrastructure Stabilization
Precision sub-surface structural support for municipal utilities, public works, and large-scale concrete structures. We remediate voids and reinforce foundation soils to extend infrastructure lifespans.
Road & Rail Crossing Grouting
Targeted void filling and ground improvement beneath critical transit corridors. Our rapid-setting techniques stabilize track slabs and road bases with minimal disruption to traffic or rail schedules.
Airport Runway Stabilization
High-bearing-capacity slab lifting and base stabilization for taxiways and runways. We utilize high-density materials engineered to handle immense dynamic loads while meeting strict aviation window timelines.
Dam & Water Control Grouting
Advanced seepage mitigation, curtain grouting, and structural sealing for dams, reservoirs, and spillways. Built to withstand high hydraulic gradients and prevent catastrophic water migration.
Confined Space Grouting
Specialized, low-profile injection systems operated by trained technicians. Purpose-built for tight, hazardous, or restricted-access subterranean environments where standard equipment cannot fit.
Precision
into Every Injection
Specialized Fleet & Equipment
We own and operate purpose-built, high-capacity grout plants and delivery systems capable of handling complex multi-component mixes.
Custom Mix Designs
No two ground conditions are identical. We formulate custom cementitious, chemical, and polyurethane grouts tailored to your specific geology.
Uncompromising Safety Culture
Fully compliant with stringent mining and heavy civil safety standards. Our crews are trained for confined spaces and hazardous environments.
Frequently Asked Questions
Specialty Grouting Services Inc. is a specialist grouting contractor based in Ontario, Canada. We stop water inflows in concrete structures, fill voids, provide structural grouting repairs, fill annular spaces, and abandon redundant pipes with flowable grout.
We are based in Ontario and complete most of our work here, and we travel across Canada and internationally for the right project. There is no job site too remote to discuss.
Consulting engineers, municipalities, general contractors, mines, and property managers bring us in as the specialty subcontractor when water inflows, voids, or failing concrete structures are beyond general-purpose repairs.
Call 226-820-4233 or send your project details to bill@sgservices.ca. Photos, drawings, soil reports, or an RFP help us respond with an accurate approach and price.
