Hamilton's Premier Interlocking
& Hardscape Contractors
Driveways, patios, walkways, retaining walls & armour stone — built on properly engineered bases that survive Hamilton winters for decades.
What Separates a Great Interlock Job From One That Fails in 5 Years?
In Hamilton, poorly installed interlocking is a serious problem. Our freeze-thaw cycles — where ground temperatures swing from -20°C to +30°C — destroy interlock that wasn't built on a properly engineered base. Most homeowners can't tell the difference until it's too late and their driveway is sinking, cracking, or shifting. Here's what Antoine Landscape Contractors does differently.

Book a Free ConsultationThe Antoine Landscape Contractors Interlocking Installation Process — Step by Step
Every interlock project we build follows this exact process. No shortcuts. No exceptions.
Free Site Consultation & Design
We visit your property, measure the space, assess drainage and grade, and discuss your vision. We walk you through material options and present a detailed scope with pricing before any agreement is signed.
Why this matters: You get a custom plan, not a generic quote.1Excavation & Removal
We excavate to a minimum of 8–12 inches depth depending on application (driveways require more than patios). We haul away all soil and existing materials, leaving a clean, deep working area.
Why this matters: The depth of excavation determines how long your interlock lasts.2Geotextile Fabric & Granular Base
Geotextile landscape fabric is laid first to prevent base migration. Then we install and compact granular base material in lifts using a plate compactor — never one deep dump. This is where most contractors cut corners.
Why this matters: This layer prevents settling and weed growth for decades.3Bedding Sand & Grading
A 1-inch layer of clean bedding sand is precisely screeded to achieve the correct grade — minimum 2% slope away from structures. We use laser levels for accuracy, not eyeballing.
Why this matters: Perfect grade = no water pooling on your finished surface.4Stone Installation & Cutting
Stone is laid in your chosen pattern, cut with a wet saw for precise edges, and bordered with a soldier course and aluminum or plastic edge restraint. Every piece is hand-placed and checked for level.
Why this matters: Precision cuts = clean finished look with no gaps.5Polymeric Sand & Final Compaction
Polymeric sand is swept into joints, compacted with a plate compactor (rubber pad to protect stone surface), and activated with water. This locks all stones together and seals the surface against weeds and erosion. A final inspection and cleanup completes the job.
Why this matters: Polymeric sand locks stones in place and prevents ants and weeds.6
Every one of our interlock projects follows this exact process. When you hire Antoine Landscape Contractors, you're not guessing — you're getting a system that works.

What Our Customers Say About Our Interlock Work
"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."
Is Your Existing Interlock Sinking, Shifting, or Uneven?
Many Hamilton homeowners assume sinking or uneven interlock needs to be completely replaced. In most cases, it doesn't. We can lift existing stone, regrade the base, and relay everything — saving you thousands compared to starting fresh.
- Stones sinking or dipping
- Water pooling in spots
- Stones rocking underfoot
- Sand washing out of joints
- Visible gaps between stones
- Edge restraint pulling away
Repair vs full replacement: Repair is ideal when the stone itself is in good condition and the failure is in the base or jointing. Full replacement is needed when stone is cracked, heavily stained, or the area has been repeatedly patched. Not sure? Book a free assessment — we'll give you an honest recommendation.

Frequently Asked Questions About Interlocking in Hamilton
Properly installed interlocking with a correct base should last 25–40 years or more. The key word is 'properly' — depth of base, quality of compaction, type of jointing sand, and edge restraint all determine longevity. Hamilton's freeze-thaw cycles are tough on poorly built interlock but have no impact on well-engineered installations.
For driveways, we typically excavate 10–12 inches and install 8–10 inches of compacted granular base plus 1 inch of bedding sand. For patios and walkways, 6–8 inches of base is standard. Less than this in Hamilton's climate will result in settling and heaving.
All three are reputable Canadian manufacturers. Cambridge offers the widest style range and lifetime warranty. Unilock is a premium option with superior colour technology (EnduraColor). Permacon is strong value for classic looks. We'll bring samples to your consultation and help you choose based on your style, application, and budget.
In many cases, yes. If the stone itself is in good condition, we can lift and relay it with a proper base regrading. This typically costs 40–60% less than full replacement. We'll assess your existing interlock honestly and recommend the most cost-effective solution.
Interlock driveways and patios typically don't require permits in Hamilton. Retaining walls over a certain height (usually 0.6m) may require a permit. We handle all permit research and applications as part of our service.
A typical residential driveway takes 2–4 days on site depending on size and complexity. Factors include excavation depth, drainage requirements, and stone pattern complexity. We give you a realistic timeline before we start.
Polymeric sand is a specialized jointing sand that contains binding agents. When activated with water, it hardens to lock your stones in place and resist washout, ant infiltration, and weed growth. Regular sand washes out quickly and allows stones to shift. We use polymeric sand on every installation.
We serve all of Hamilton including the Mountain, Ancaster, Dundas, Stoney Creek, Waterdown, Binbrook, Glanbrook, and Flamborough, as well as Burlington and Oakville.
