Concrete Work in Saint-Jérôme

Broom (non-slip, standard outdoors), steel trowel (smooth, indoor), exposed aggregate, stamped/patterned, coloured and polished. Decorative finishes can add 30-100% to the base rate but replace the cost of a separate surface like pavers or tiles.

You can usually walk on it after 24-48 hours, drive on it after about 7 days, and it reaches design strength at 28 days. Curing (keeping it damp, protecting from frost or extreme heat) in the first week matters more for durability than almost anything else.

Look for crews who do concrete daily, not general handymen — finishing is a perishable skill and a two-hour window decides how the slab looks forever. In Saint-Jérôme, ask for addresses of slabs poured a few years ago and look at the joints and edges, which is where poor work shows first.

Hairline shrinkage cracks are normal; that is what control joints are for — they give cracking a straight place to happen. Wide, uneven or lifting cracks signal a base, reinforcement or curing problem. If a new slab cracks outside its joints within months, call the contractor back.

Strongly. Frost can ruin an uncured pour, extreme heat causes plastic shrinkage cracking, and rain marks fresh surfaces. Good contractors watch forecasts and will delay a pour; be suspicious of anyone happy to pour into bad weather to keep the schedule.

Usually the wrong mix (no air entrainment), finishing water into the surface, or salting a first-year slab. Insist on the CSA exposure-class mix, proper curing, and avoid de-icing salt during the first winter.
