About us

About Grade Line Concrete

21Years of experience

Grade Line Concrete pours concrete that is still flat when the warranty is long expired, and almost all of that comes down to what happens before the truck arrives: strip the topsoil, build and compact the base, set the reinforcement at the right height, form to a grade that drains. We cut the joints on time, we cure it properly, and we tell you to hold off sealing until it is ready.

What we do

Concrete services in Milton

Driveways, walkways, slabs and steps poured on a base built for our frost cycle. Grade Line Concrete will state the thickness and base depth in writing.

  • Driveways & walkways

    Poured on a compacted granular base with fibre or mesh reinforcement, sloped to drain and control-jointed so the cracks land where we put them.

  • Garage slabs & equipment pads

    Slabs poured to thickness with proper base prep and reinforcement, including pads for hot tubs, sheds and generators.

  • Stamped, exposed aggregate & broom finish

    Decorative finishes coloured and sealed on site — stamped patterns, exposed aggregate, or a clean broom finish that never goes out of style.

  • Steps, porches & landings

    Formed and poured on footings below the frost line so the steps stay attached to the house instead of drifting away from it.

  • Foundations, footings & piers

    Footings and foundation walls for additions, garages and decks, formed square and inspected before the pour.

  • Concrete repair & resurfacing

    Crack repair, spall patching and overlay resurfacing where the slab is structurally sound and only the surface has gone.

  • Removal, sawcutting & disposal

    Old concrete broken out, sawcut cleanly where only part of it goes, and hauled away as part of the quote.

  • Sealing & winter protection

    Penetrating sealer applied once the concrete has cured, which is the difference between a driveway that scales in year two and one that does not.

Questions

Frequently asked

If your question isn't here, call us — we would rather explain it than have you guess.

Walk on it after about 24 to 48 hours, drive a car on it after about seven days, and keep heavy trucks and trailers off for a full 28 days — that is when the concrete reaches its design strength. Driving on it early is one of the few ways to crack a properly built slab.

All concrete cracks; the job is controlling where. We cut or tool control joints at the right spacing and depth so the shrinkage cracks form inside the joints where you will not notice them. What should not happen is random cracking across the middle, which points to a bad base, no reinforcement or joints that were cut too late or too shallow.

Roughly late spring through fall is ideal. Concrete needs to stay above freezing while it sets, so cold-weather pours require blankets, heated enclosures and accelerators, and cost more. Very hot, windy days are their own problem because the surface dries faster than the slab below. We schedule around the forecast rather than the calendar.

Yes for exterior concrete in a salt climate, and no earlier than about 28 days after the pour — sealing green concrete traps moisture and causes exactly the surface scaling you are trying to prevent. Then reseal every couple of years. Also keep de-icing salt off new concrete for the entire first winter.

More than most people ask about, which is why bad driveways are so common. A proper job means the topsoil is stripped out, granular base placed and compacted in lifts, and reinforcement placed at the right height in the slab. That base is why one driveway is still flat at fifteen years and the neighbour's has heaved. Our quotes state the slab thickness and base depth in writing.

Yes — breakout, haul-away and disposal are in our quote, along with the excavation for the new base. If your quote from anyone else does not mention removal and disposal, ask, because it is a real cost that has to land somewhere.
