Below the surface
A foundation matched to the load.
Our process considers grade and drainage first. Vehicle-load driveways typically use an 8–12 inch compacted granular base and 80 mm pavers; patios and walkways use 6–8 inches and typically 50–60 mm pavers. Geotextile is used where soil conditions call for it, including clay found in parts of Hamilton. We compact in lifts, screed one inch of bedding, restrain the edges and finish the joints with polymeric sand.
What's under an interlock surface
Everything below the pavers — the compacted stone base, the sand bed and the edging — is what keeps the surface flat for decades.
Driveway: Typical dig: about 12–16 in below the finished surface.
Pavers: Usually 80 mm (3⅛ in) thick for vehicle loads. Thicker units spread tire loads and resist cracking.
Joint sand: Polymeric sand swept into every joint. Locks the pavers together and keeps out weeds and ants.
Bedding layer: About 1 in of screeded sand. A flat, even bed the pavers are set into — never used to fix low spots.
Granular base: 8–12 in of crushed stone, compacted in lifts. This is what carries the weight. Compacting in thin layers stops it settling later.
Geotextile fabric: Where the soil needs it (common on Hamilton clay). Keeps the stone base from sinking into soft clay over time.
Native soil: Excavated, levelled and compacted. A firm, properly sloped subgrade so water drains instead of pooling.
Edge restraint: Spiked along every open edge. Holds the outer pavers so the surface can't creep apart.
Patio & walkway: Typical dig: about 9–12 in below the finished surface.
Pavers or slabs: Typically 50–60 mm (2–2⅜ in) thick. Foot traffic needs less thickness than a driveway.
Joint sand: Polymeric sand swept into every joint. Locks the units together and keeps out weeds and ants.
Bedding layer: About 1 in of screeded sand. A flat, even bed the pavers are set into.
Granular base: 6–8 in of crushed stone, compacted in lifts. Spreads the load and stops low spots forming.
Geotextile fabric: Where the soil needs it (common on Hamilton clay). Keeps the stone base from mixing into soft clay.
Native soil: Excavated, levelled and compacted. A firm, properly sloped subgrade.
Edge restraint: Spiked along every open edge. Holds the outer pavers so the surface can't creep apart.
Permeable: Usually deeper than standard interlock — the stone layers also store rainwater. Depth is set by the design.
Permeable pavers: Units with wider joints that let water through. Rain soaks in at the surface instead of running off.
Joint aggregate: Small clear chip — not polymeric sand. Open joints keep the surface draining.
Bedding layer: About 2 in of small clear chip. Sets the pavers while letting water pass straight through.
Open-graded stone: Clean, washed stone with open spaces. Holds water temporarily while it soaks into the ground.
Sub-base reservoir: Larger clean stone — depth set by design. Extra storage for heavy rain; an underdrain carries overflow away where clay drains slowly.
Native soil: Tested and graded, left uncompacted where it should absorb water. Water infiltrates here, or drains through the underdrain on clay.
Edge restraint: Spiked along every open edge. Holds the outer pavers so the surface can't creep apart.
Typical dig: about 12–16 in below the finished surface. (Grey block at left is the house foundation.)
Why the base matters in an Ontario winter
Shallow or poorly compacted baseWater collects in the clay, freezes into ice lenses and pushes pavers up unevenly — trip edges and puddles by spring.Built to specA deep, compacted, draining base keeps frost and water away from the pavers, so the surface stays flat.

Driveway approvals
Check before you change the driveway.
Hamilton's front-yard green-space rule and driveway access approval, Burlington's Driveway Modification Bylaw and Oakville's driveway permit procedure can affect a project. Backyard patios and walkways usually do not require a building permit, but drainage, grading, coverage and conservation rules can still apply. Confirm current requirements with your municipality.
Hamilton's Residential Driveway Access rules and 50% front-yard green-space requirement still apply; check whether your work changes the approach.

Repair, not always replacement
When a surface starts to settle.
Uneven stone, pooling water, rocking pavers, washed-out sand and pulling edge restraints are reasons to inspect the base. When the pavers remain serviceable, lifting, correcting the base and relaying may be possible. The condition of the site determines whether repair or replacement makes sense.
Plan grading, drainage, steps, lighting and planting alongside the hardscape.

What customers have said.
“Antoine Landscape Contractors' crew built our new driveway in Ancaster last spring. The workmanship is flawless — level, tight joints, perfect soldier course. Neighbours keep asking who did it. Zero issues through the first winter.”
“We had three quotes. Antoine Landscape Contractors was the only contractor who explained the base process in detail and showed us why the others were quoting too cheap. Their finished patio exceeded our expectations.”
“Fast, clean, professional. They replaced our crumbling concrete steps with beautiful armour stone and the difference is night and day. Would hire again without hesitation.”
“Our old interlock was sinking and uneven after 8 years. Antoine Landscape Contractors lifted and releveled everything in two days. Like brand new. Wish we'd called them sooner.”

How deep is the base under an interlock driveway?
A vehicle-load driveway typically needs 8–12 inches of compacted granular base; patios and walkways typically need 6–8 inches. Depth depends on soil and site conditions.
Do I need approval to widen my Hamilton driveway?
A new or widened driveway approach needs Residential Driveway Access approval. Hamilton also requires 50% front-yard green space under Zoning By-law 05-200. Confirm current requirements with your municipality.
Do patios need permits?
Standalone backyard patios usually do not need a building permit, but grading, drainage, lot coverage and conservation rules can apply. Confirm current requirements with your municipality.
Can settled pavers be repaired?
Often pavers can be lifted, the failed base corrected and the surface relaid. The extent and removal costs are quoted on site.
Which paver pattern suits a driveway?
Herringbone patterns interlock well under vehicle loads. The base, paver thickness and edge restraint matter as much as the pattern.
What brands and materials are available?
We install Techo-Bloc, Unilock and Permacon pavers and slabs, along with natural stone and porcelain options.
What happens before excavation?
Ontario One Call locates are required before digging. We also review grades, access and any driveway approval requirements.
Does permeable paving need a different base?
Yes. The drainage and reservoir design is site-specific, and pricing is quoted on site. Confirm current requirements with your municipality.
