Concrete Garage Floors & Slabs in Mississauga

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 Peel Region.

Why Mississauga projects need a tailored approach

Mississauga sits on Peel Plain clay over Halton Till on the north end, Iroquois beach sand south of Lakeshore Road, and the homes we work on are spread across neighbourhoods like Port Credit, Lorne Park, Clarkson, Erin Mills, Streetsville, Meadowvale, Mississauga Valleys, Cooksville and Mineola. South Mississauga lots near Port Credit and Lakeview have running sand at depth, while north Mississauga (Erin Mills, Streetsville, Meadowvale) sits on clay that holds water and heaves in winter. Combined with Lake Ontario shoreline moderation, fewer freeze-thaw cycles than inland, but high summer humidity, this changes how we design the slab and the base.

We pull permits where needed through City of Mississauga Building Division (300 City Centre Drive), so the work is documented and inspected, not buried under landscaping. Whether you are in postal code area L5A through L5W, we serve every Peel Region address with the same crew, the same supervisor, and the same written quote.

How we build a garage slab in Mississauga


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.
