Pouring concrete is more than just mixing and dumping a batch into a form. It’s a strategic process that involves preparation, precision, and finishing expertise. Whether you’re tackling a small slab or a large-scale foundation, this guide will walk you through how to pour concrete properly — step by step. Plus, we’ll share how Premier Concrete Pumping supports contractors across Ontario with equipment and on-site assistance to ensure every pour goes smoothly.
Why Proper Concrete Pouring Matters
Concrete is the backbone of modern construction. But if poured incorrectly, even the most well-designed mix can lead to cracks, settling, and structural issues. A great concrete pour starts well before the first batch is mixed — and it doesn’t end until the last joint is sealed.
Step 1: Site Preparation
A successful pour starts with proper prep.
Here’s what that includes:
-
Clearing the site of grass, trees, rocks, and debris
-
Removing old concrete if needed
-
Digging down to the proper depth (typically 4–6 inches for patios and sidewalks; 10–12 inches for load-bearing slabs)
-
Installing a sub-base using crushed stone or gravel
-
Compacting the base to ensure stability
Why it matters: Without proper prep, your slab may settle unevenly or crack prematurely.
Tip: In colder Ontario climates, a well-compacted and drained base helps prevent frost heave.
Step 2: Building and Setting the Forms
Concrete needs a mold — that’s where formwork comes in.
What’s involved:
-
Using wood or metal forms to shape the edges of the slab
-
Securing forms with stakes and screws
-
Ensuring proper slope for drainage (1/4″ per foot away from structures)
-
Double-checking square corners and level tops
Premier Pro Tip: We often advise clients on the best form layout for their slab size and slope requirements, especially on uneven terrain.
Step 3: Reinforcement – Wire Mesh or Rebar
To avoid cracks and improve load-bearing, install steel reinforcement.
Two main options:
-
Wire mesh for slabs under 5” thick
-
Rebar grid for driveways, garages, and structural slabs
Placement matters: Reinforcement should sit in the top third of the slab (not directly on the sub-base).
How Premier Helps: Not sure how much reinforcement you need? Our team can assess the project and guide you on wire mesh spacing or rebar layout.
Step 4: Mixing the Concrete
Depending on your job size, you’ll either:
-
Mix by hand or with a mixer (for small patios)
-
Use a ready-mix concrete truck (for larger projects)
Consistency matters: Aim for a peanut butter–like texture. Too soupy, and the slab will be weak; too dry, and it won’t finish cleanly.
Working with Premier: We pump ready-mix concrete for jobs across Toronto, Hamilton, Vaughan, and beyond — even when the truck can’t get close. Our operators use line pumps and boom pumps to place concrete precisely where you need it.
Step 5: Placing the Concrete
Once the concrete arrives, work fast.
Tools you’ll need:
-
Rakes or “come-alongs” to spread the mix
-
Shovels for edges and corners
-
Vibrators (optional) to remove air pockets
Technique:
-
Pour evenly and continuously to prevent cold joints
-
Fill the forms to the top without overfilling
-
Don’t overwork the concrete — it’ll start to set quickly, especially in warm weather
Premier Advantage: We help contractors control pour speed and placement by coordinating the pump rate to match finishing crew pace.
Step 6: Screeding and Initial Finishing
Screeding means leveling the surface.
Steps:
-
Use a long straightedge or screed board to drag across the top
-
Smooth out humps and fill low spots
-
Bull float the surface to embed aggregates and bring up the paste
This step sets the stage for your final finish.

Step 7: Edging, Jointing, and Final Finish
As the concrete begins to set:
-
Edge the perimeter with an edging tool
-
Cut control joints to reduce cracking (typically 1/4 depth of the slab, spaced 2–3x the slab thickness in feet)
-
Apply the finish (broom, stamp, or smooth trowel)
Tip: For patios, sidewalks, and driveways in Ontario, we recommend broom finishes or exposed aggregate for slip resistance in wet and icy conditions.
Step 8: Curing the Concrete
Concrete gains strength as it cures — not dries.
Do this to cure properly:
-
Spray a curing compound or cover with curing blankets
-
Keep moist for 7 days if possible
-
Avoid heavy use for at least 7 days; full cure takes 28 days
Cold Weather Curing:
If you’re pouring in temperatures under 10°C (50°F), use insulated blankets. Avoid pouring under -7°C (20°F) without special precautions.
Extra Tips from the Field
Here’s what we’ve learned supporting pours across Southern Ontario:
-
Don’t pour on frozen ground
-
Use pumps when the truck can’t get near the forms — we’ve seen jobs ruined trying to wheelbarrow 10m³ of concrete uphill
-
Always compact your base — 80% of slab issues are caused by poor prep
-
Book your equipment in advance, especially in peak season (April to October)
