Water controlled. Voids filled. Structures supported.
Specialty Grouting Services provides specialist grouting services across Ontario and beyond — from stopping active water inflows in a single manhole to filling kilometres of abandoned pipe. Every service below is delivered by our own crews with our own purpose-built equipment.
What does a specialty grouting contractor do?
A specialty grouting contractor injects or places grout — cementitious mixes, water-activated polyurethane, low-density cellular concrete (LDCC), epoxy, or foam — to stop water, fill voids, and restore structural support below grade. General contractors handle the broad scope of a project; we handle the part where material has to go into ground or concrete you cannot see, and perform exactly as intended.
Specialty Grouting Services
Targeted geotechnical solutions to stabilize structures, control water, and mitigate risk.
Groundwater Control & Mitigation
Stop active water infiltration in tanks, reservoirs, manholes, chambers, vaults, pipes, and parking garages with chemical and cement injection grouting.
Soil Stabilization & Ground Improvement
Reinforce weak soils, arrest settlement, and improve bearing capacity with precision ground injection — before or during construction.
Annular Space Grouting
Fill the space between host and carrier pipes completely, using LDCC and sanded mixes placed at pressures that protect the liner.
Void Filling & Structural Support
Locate and fill washouts and sub-surface voids, stabilize sinking slabs and foundations, and rebuild concrete with form-and-pump structural grouts.
Pipe Abandonment & Decommissioning
Fill redundant watermains, sewers, culverts, and pipelines with highly flowable grout for a safe, documented closure.
Additional Specialty Services
The same crews, equipment, and materials applied to structures above ground and below.
Concrete & Structural Repairs
Crack and joint injection, patching, parging, dowelling, form-and-pump grouting, and concrete coring for bridges, parking garages, and structures.
Heritage Masonry Grouting
Consolidation and void-filling grouting for heritage stone and brick — churches, barns, lighthouses, and historic buildings.
Foundation Leak Repairs
Residential and commercial basement and foundation crack injection — leaks stopped permanently from the inside, no excavation.
On-Site Technical Support
Grouting equipment rentals, material supply, and pumping and placement support for crews self-performing a grouting scope.
Confined Space Entry Projects
Inspections, cleaning, condition assessments, leak sealing, benching, ladder and landing installations, and repairs inside manholes, chambers, and vaults.
Which grouting method is right for my project?
It depends on what the ground and the structure are doing — there is no one right grout. Flowing water usually calls for water-activated polyurethane; large voids may call for LDCC or sanded cementitious mixes; structural rebuilds may call for form-and-pump placement or epoxy. Send us your specifications, soil reports, or photos and we will recommend the method and material honestly, including when grouting is not the right fix.
Not Sure Where Your Problem Fits?
Describe what you’re seeing — water, settlement, a failing structure — and a grouting specialist will point you in the right direction.
