Over time, even the toughest concrete surfaces wear down. Whether you're dealing with severe cracks, foundation issues, or outdated structures, there comes a point when repair simply isn’t enough. That’s when full concrete demolition becomes the smart move - not just for structural integrity, but also for aesthetics, functionality, and safety.

This guide walks you through what full concrete demolition involves, why you might need it, and how to prepare for it like a pro.

1. Understanding What Full Concrete Demolition Entails

Full demolition means removing an entire concrete structure - be it a driveway, patio, slab, or foundation - down to the subgrade. It’s not patchwork or cosmetic resurfacing. It’s starting fresh.

Typical structures that may require full demo:

• Severely cracked or shifting slabs

• Water-damaged foundations

• Patios or driveways with incorrect slope/drainage

• Non-compliant concrete built without permits

• Outdated layouts ready for remodeling

2. When Repair Isn’t Enough: Signs You Need Full Demo

✅ Deep structural cracks that keep reappearing
✅ Heaving or sinking from freeze-thaw cycles or erosion
✅ Water pooling or improper drainage leading to property damage
✅ Poor quality concrete that’s crumbling or dusting
✅ Plans to build new structures (like garages or additions) on the space

If two or more of these apply, repairing might cost more over time than full removal and replacement.

3. The Demolition Process, Step by Step

At Northform Concrete, we follow a precise, safe, and clean demolition workflow:

1. Site Inspection & Utility Locating – Ensuring no underground lines are damaged

2. Permit & By-law Checks – Municipal compliance in Ontario is a must

3. Equipment Mobilization – Excavators, jackhammers, saws, and more

4. Concrete Breaking & Removal – Controlled sectioning, dust control, and clean hauling

5. Site Prep or Cleanup – Either leave a clean subgrade or prep for your next concrete pour

We dispose of all debris responsibly, prioritizing recycling whenever possible.

4. Cost Factors to Consider

Pricing for full demolition typically depends on:

• Square footage & thickness of concrete

• Site access & removal logistics

• Reinforcement (rebar vs. mesh)

• Equipment needs (manual vs. mechanical)

• Disposal and hauling fees

💡 Average ballpark for Ontario homes: $8–$15 per sq. ft.
