8-Step Process
Our Concrete Slab Pouring Process
Site Assessment & Measurement (Free)
Measure area and check grades. Assess existing conditions (old slab, soil, drainage). Determine drainage requirements and slope needs. Soil/sub-base evaluation for settlement risk.
Excavation & Sub-Base Preparation
Excavate to required depth (varies by slab type). Compact native soil with machine. Install granular base: 4-6" of 3/4" clear stone or granular A, machine compacted. Proper sub-base is 90% of a good slab - this is where cheap contractors cut corners.
Drainage & Utilities
Rough-in floor drains, sump pit, weeping tile connections. Stub up plumbing for future bathroom/kitchen if planned. Install in-floor heating tubing (PEX) if requested. All drainage connected before concrete is poured.
Vapour Barrier
6-mil polyethylene vapour barrier over entire sub-base. Overlapped 12" at seams, sealed with tape. Prevents moisture migration through slab - critical for finished basements. Many contractors skip this → leads to damp floors, mold under flooring, efflorescence on walls.
Reinforcement
Welded wire mesh (WWM 6x6 W1.4/W1.4) for standard slabs. Rebar grid (10M @ 12" O.C. both ways) for garage/driveway. Rebar placed on chairs to maintain proper position in slab. Fibre-reinforced concrete available as supplement (not replacement) for mesh.
Forming
Build perimeter forms to exact grade with laser level. Control joint layout planned (max 10' spacing or 2:1 length-to-width ratio). Expansion joints where slab meets walls, columns, or other slabs. Forms must be level and straight.
Pour & Finish
30 MPa concrete (standard) or 32 MPa (garage/driveway). Pump or wheelbarrow delivery depending on access. Screed to level, bull float for initial finish. Final finish options: smooth trowel, broom, stamped, exposed aggregate. Control joints cut within 12-24 hours after pour.
Curing & Protection
Curing compound applied OR wet cure with poly cover for 7 days. No foot traffic for 24-48 hours. No vehicles for 7 days minimum. Full strength at 28 days. Seal coat recommended at 28 days for garages/driveways to protect against salt and oil.
Technical Specifications
Slab Specifications by Type
Engineered specifications for each application
| Slab Type | Thickness | Concrete Strength | Reinforcement | Sub-Base | Vapour Barrier |
|---|---|---|---|---|---|
| Basement floor | 4" (100mm) | 30 MPa | WWM or rebar | 4" granular | Yes (required) |
| Garage pad | 5-6" (125-150mm) | 32 MPa | Rebar grid | 6" granular | Recommended |
| Patio | 4" (100mm) | 30 MPa | WWM | 4" granular | No |
| Driveway | 5-6" (125-150mm) | 32 MPa | WWM + rebar edges | 6" granular | No |
| Walkway | 4" (100mm) | 30 MPa | WWM | 4" granular | No |
| Pad footing | 12-24" deep | 25-30 MPa | Rebar per eng. | Undisturbed soil | No |
These Specs Are Non-Negotiable
These specifications are based on Ontario Building Code, soil engineering best practices, and 20+ years of experience pouring slabs in GTA soil conditions.
Any contractor who suggests thinner slabs, weaker concrete, or skipping the sub-base or vapour barrier is trying to cut corners. That slab WILL crack, heave, or fail prematurely.

DON'T GET SCAMMED
Why Sub-Base Matters (This Is Where Cheap Contractors Cut Corners)
The difference between a 5-year slab and a 50-year slab
The #1 Reason Slabs Fail
Bad sub-base preparation
Cheap contractors pour on dirt
No granular base = settlement, cracking, heaving in freeze-thaw
They skip the vapour barrier
Moisture migrates through slab → damp floors, mold, efflorescence
They don't compact the sub-base
Hand-tamped or not compacted at all = voids underneath = cracking
They use too little granular
2\" when it should be 4-6\" = inadequate load distribution
The DrySpace Way
We NEVER skip sub-base
4-6\" compacted granular base
3/4\" clear stone or granular A, machine compacted to 95% density
6-mil vapour barrier on every basement floor
Prevents moisture migration - critical for finished basements
Proper control joint layout
Max 10' spacing or 2:1 ratio - planned BEFORE we pour
WWM or rebar on chairs
Reinforcement placed at proper height in slab (not flat on ground)
ASK ANY CONTRACTOR: "What's your sub-base specification?"
If they can't answer or say "we pour on the existing soil", WALK AWAY.
A proper sub-base costs $2-3/sq ft. Skipping it saves the contractor money but GUARANTEES your slab will fail within 5-10 years.
