Interlocking is our bread and butter. GDS Landscaping and General Contracting is a Barrie-based interlocking company installing driveways, patios, and walkways across Barrie and Simcoe County. We do the excavation, base, and stone work ourselves with our own crew — no subcontracting the core of the job.
Interlocking done wrong in Barrie heaves after one winter. Done right — with a properly compacted base and drainage that actually moves water away from your house — it lasts decades. That’s the work we do, and every job gets a free on-site quote before we start.
Interlocking Driveways in Barrie
A driveway takes the full weight of your vehicles, plus frost heave every winter. That’s why the base matters more than the paver you pick. We excavate to the right depth, compact granular base in lifts, and set the stone on a level screeded bed — so the driveway stays flat and drains properly instead of settling into ruts. Border courses, soldier rows, and drain grates are part of the plan, not extras we spring on you later.
Interlocking Patios & Walkways
Patios and walkways get built the same way as driveways, just finished for foot traffic: tighter patterns, clean edges, and a polymeric sand finish that keeps weeds out of the joints. Whether it’s a small front walkway, a full backyard patio, or a fire-pit pad, we match the stone style to your house and your budget.

Interlocking FAQs
Q: How much does an interlocking driveway cost in Barrie?
A: Interlocking driveways in Barrie typically run $20–$30+ per square foot installed, depending on access, excavation depth, stone choice, and drainage work. We give free on-site quotes so you get a real number for your property, not a guess.
Q: How long does an interlocking driveway last in Ontario?
A: With a proper compacted base and drainage, an interlocking driveway in Barrie can last 25+ years. The jobs that fail early almost always have a thin or poorly compacted base — that’s where most of the work (and cost) actually goes.
Q: What time of year is best for interlocking in Barrie?
A: Late spring through fall is ideal, when the ground is workable and base materials compact properly. We book jobs through the season — call early in spring for the best scheduling.
Q: Do you also do repairs or re-leveling of old interlocking?
A: Yes. If your existing interlocking has settled, heaved, or spread, we can lift the stone, fix the base, and re-lay it. A re-level is usually a fraction of the cost of a full replacement.

Interlocking vs stamped concrete — which is better for a Barrie driveway?
Interlocking handles Ontario freeze-thaw better because individual pavers flex instead of cracking, and repairs are invisible. That’s why most Barrie driveways we build are interlock.
Can you repair sunken or uneven interlock?
Yes — we lift, re-level the base and relay sunken interlock so it drains properly and looks new again.
How long does an interlock driveway last?
25+ years with a proper compacted granular base and polymeric sand joints — which is exactly how we build every project.
Do you install interlock walkways and borders too?
Yes — walkways, porch landings, garden borders and driveway aprons, all matched to your main paved areas.
