Interlocking Driveway Installation

Why Interlocking Stone Stands Out

Interlocking pavers are the premium option for Ontario driveways — and they earn that premium. Unlike poured asphalt or concrete, interlocking stone doesn't crack. Each individual paver moves independently with the ground, which matters a lot in a climate where the soil freezes six inches deep every winter and thaws unevenly in spring.

The other thing homeowners appreciate: interlocking driveways don't need sealcoating, they don't fade the same way asphalt does, and a single damaged paver can be lifted and replaced without touching the rest of the surface. That's a repair advantage no other material offers.

How We Build an Interlocking Driveway

1. Excavation

We excavate to a minimum depth of 15 inches for residential driveways. Ontario's frost line demands a deep base — anything less and you'll see heaving and shifting within the first two winters. All organic material and topsoil gets removed completely.

2. Granular Base

We lay Granular A limestone in 4-inch lifts, compacting each layer with a plate tamper. Total base depth is typically 10 to 12 inches for driveways. This isn't decorative stone — it's engineered aggregate sized to lock together and distribute vehicle loads evenly.

3. Bedding Layer

A 1-inch layer of coarse concrete sand (HPB) gets screeded to a precise, uniform depth. This is what the pavers sit on. If the bedding isn't level, the finished surface won't be either — you'll see it in every joint line.

4. Paver Installation

Pavers go down by hand, following the chosen pattern — herringbone, basketweave, running bond, or custom layouts. Herringbone is our standard recommendation for driveways because it interlocks under load better than other patterns. It's the same pattern used on city streets and commercial plazas for that reason.

5. Edge Restraints

Aluminum or polymer edge restraints get spiked into the base along every border. Without proper edge restraint, pavers migrate outward over time and the joints open up. This is one of the most common failure points we see on DIY or poorly installed driveways.

6. Polymeric Sand & Compaction

Once all pavers are set, we sweep polymeric sand into every joint and compact the entire surface with a plate tamper (using a neoprene pad to avoid scratching the paver faces). The polymeric sand hardens when wet, locking everything in place and preventing weed growth and ant hills in the joints.

Materials We Work With

• Concrete pavers — the most common choice. Brands like Unilock, Techo-Bloc, Permacon, and Oaks offer hundreds of styles, colours, and textures. 60mm thickness for residential, 80mm for commercial.
• Natural stone — granite, limestone, sandstone. Higher cost, unique appearance, each piece is different. Best for walkways and patios where a natural look matters.
• Porcelain pavers — a newer option. Extremely hard, virtually zero water absorption, consistent colour. Higher material cost but very low maintenance.
• Permeable pavers — designed with wider joints or built-in gaps to let water pass through to the base below. Useful where municipal stormwater bylaws require on-site infiltration.

Cost Range

Interlocking driveway installation in the GTA typically runs $15 to $30 per square foot, depending on the paver selected, base conditions, and design complexity. A standard two-car driveway (400-600 sq ft) usually falls between $8,000 and $18,000.

That's more than asphalt, but the lifetime cost is closer than most people expect — interlocking doesn't need sealcoating, individual pavers can be replaced for a few dollars each, and the surface generally outlasts asphalt by a decade or more.

Where We Install

We install interlocking driveways, walkways, and patios across the GTA — Toronto, Vaughan, Mississauga, Brampton, Markham, North York, Scarborough, and Richmond Hill.
