Poured Concrete Driveways in Thunder Bay, ON

5-star ratings from Google

On-site work usually runs two to four days. Tear-out and hauling the old slab out is day one, base and forms follow, and the pour and finish happen in a single day because concrete does not wait. What takes longer than the work is the cure. You can walk on it after about a day and you need to keep vehicles off for seven. Plan your parking for the week rather than for the pour.

We quote each driveway after measuring it, because the variables move the number too much for a published figure to help you. Tear-out and disposal, how much grade has to be cut, slab thickness for what you park on it, reinforcement, and whether a truck can reach the pour all change it. The estimate itemises removal, base, concrete, finish, and jointing so you can compare it honestly against other quotes. The consultation is free.

For passenger vehicles, 100 mm is the standard minimum across Canadian industry guidance. If you park a truck, an RV, or a trailer on it, that goes up. Thickness is only half the answer though. A thick slab on a poor base will still fail, and a properly built base under a standard slab will outlast it. Anyone quoting you on thickness alone is describing the cheap half of the job.

Look at whether the damage is on the surface or coming from under it. Flaking and peeling across the surface is scaling, and it keeps spreading because the cause is in the concrete itself. Cracks with a lip, sunken sections holding water, and patches that reopen every second spring point at the base. Surface scaling and base failure are both replacement conversations. A single tight crack in an otherwise flat driveway usually is not, and we will tell you that.

It depends on where you land in the season. Concrete work in Thunder Bay is weather-bound, the schedule fills through the summer, and we do not offer same-day or emergency driveway work. What we can do quickly is come out and quote it. Getting on the schedule early in the season is the practical move, because the late-season slots come with cold-weather constraints.

Cold weather pouring is governed by the code rather than by preference. Once air temperature is likely to fall below 5 C within 24 hours of placing, the concrete has to go in at a minimum of 10 C and be held there for 72 hours with heat, blankets, or hoarding, and it cannot be placed on frozen ground. Beyond that, new concrete needs roughly a month of air drying before it faces freeze-thaw cycles, which is what really ends the driveway season here. We assess late-season work job by job.

Not the first winter. Concrete Ontario's guidance is that no de-icer of any type should go on new concrete through its first winter, and that sand is the right choice for traction instead. New concrete's air voids are still saturated and cannot do their job yet, so de-icer at that stage causes scaling, which is the surface flaking off. After the first year, plain rock salt in light applications is the least damaging option. Never use anything containing ammonium sulfate, ammonium nitrate, calcium chloride, or magnesium chloride.

Yes. Breaking out the old slab, loading it, and taking it off site is part of the job and it is itemised on the estimate so you can see what that portion costs. You do not need to arrange a bin or a disposal run yourself.

Probably somewhere, eventually, and any contractor who promises otherwise is selling you something. The industry position is straightforward: all concrete tends to crack, and it cannot be made completely crack-free. What can be controlled is where and how wide. Control joints cut to a quarter of the slab depth give the concrete a straight line to crack along, and a proper base stops the kind of movement that causes wide, lipped cracks. Our satisfaction guarantee covers coming back out for hairline cracking and joint spalling.
