Replace cracked or sloping garage floors, pour the slab for a new detached garage, or upgrade to a hard-trowel polished finish. Insured concrete contractor working across City of Hamilton.

Why Hamilton projects need a tailored approach

Hamilton sits on Queenston shale on the Mountain, Iroquois sand and lacustrine clay below the escarpment, and the homes we work on are spread across neighbourhoods like Stoney Creek, Ancaster, Dundas, Westdale, Kirkendall, Stipley, Crown Point, Eastmount, Hamilton Mountain and Waterdown. Mountain lots above the escarpment frequently hit shale within 900 mm, requiring rock-saw work or rebar dowels. Lower city lots in Westdale and Crown Point have variable fill from older infrastructure. Combined with Snow-belt above the escarpment, lake-effect lower city, 20-plus freeze-thaw cycles, escarpment groundwater seeps, this changes how we design the slab and the base.

We pull permits where needed through City of Hamilton Building Services (71 Main Street West), so the work is documented and inspected, not buried under landscaping. Whether you are in postal code area L8E through L9C, we serve every City of Hamilton address with the same crew, the same supervisor, and the same written quote.

How we build a garage slab in Hamilton


Our garage-slab process

  1. Step 1. Site visit and measurement. We confirm slab thickness, drainage direction, and any service penetrations (drains, conduit, EV charger feeds).
  2. Step 2. Demolition and removal of the failed slab. We protect the foundation wall, sill plate and door track during break-out.
  3. Step 3. Sub-grade preparation. Excavate to depth, compact, install Granular A in 100 mm lifts and re-compact, then place the vapour barrier and rebar mat.
  4. Step 4. Pour day. We pour at 32 MPa, screed to grade, bull-float, edge, and hard-trowel to a smooth finish suitable for epoxy or stain.
  5. Step 5. Saw-cutting and curing. Control joints saw-cut within 12 hours, then 7 days of moist curing or curing compound depending on weather.
  6. Step 6. Final walkthrough. We pull forms, clean the apron, and walk the slab with you before invoicing.
