About this trade
Commercial concrete in Calgary needs three things to land well — formers who understand the engineering, pourers who handle Calgary's freeze-thaw, and finishers who can deliver to spec. Different crews own different stages.
Syndex sends your request to reviewed commercial concrete members, and each says for themselves which part of the work is theirs.
Common project types
What Calgary GCs hire concrete subs for.
Slab on grade
Warehouse, retail, light industrial. Vapour barrier, rebar tie, pour, finish.
Parkade decks
Suspended slabs, post-tensioned where required. Coordinated with structural and waterproofing.
Sidewalks & curbs
Site concrete: walkways, curbs, ramps, ADA accessibility upgrades.
Polished concrete floors
Floor diamond grinding and polish to spec gloss. Densifier, sealer, joint fill.
Footings & foundations
Strip footings, pier footings, foundation walls for additions and new builds.
What to know when hiring
Four things GCs check before they sign.
Formers vs pourers vs finishers
Many concrete jobs need separate crews for forming, pouring, and finishing. Confirm scope split — or that the same crew does all three.
Polished concrete is a specialty
Polish is grinding, not just sealer. Spec the gloss level (typically 800 or 1500 grit), and confirm the crew has done polish-to-spec before.
Watch the freeze-thaw window
Calgary spring and fall pours need heaters and hoarding. Confirm the sub's cold weather pour protocol.
Rebar inspection before pour
Structural concrete needs rebar inspection before pour. Confirm the sub coordinates with the engineer for sign-off.
How Syndex works for this trade
Post the job once with the scope, the location and the start date. It goes to every reviewed concrete member who covers that part of Calgary, and you see the ones who reply Yes or Call me, with their contact details and, where we hold one, the date on their WCB clearance letter.
Say whether you need forming, placing, finishing, or all three, and whether the pour falls in a cold-weather window.
Frequently asked
Concrete hiring — questions GCs ask first.
- What should I ask a concrete sub about cold-weather pours?
- Ask for their cold-weather protocol in writing: heaters, hoarding, blankets and how they monitor curing. Calgary spring and fall pours need it, and it should be priced, not assumed.
- Can the same crew handle formwork and pour?
- Many can. Some pour-and-finish crews don't form. Specify the scope in your post.
- Can a concrete sub do polished floors?
- Polishing is grinding to a specified gloss, a specialty of its own. Put the polish spec in the request and ask the crew who replies for a recent floor.
- Does Syndex cover residential concrete?
- No. Commercial only.
