Driveways & Private Road Construction Built for Ontario Winters
Georgian Bay Siteworks builds gravel driveways, cottage lanes and private roads across the region — graded, crowned and compacted so they shed water and survive freeze-thaw, spring melt and plow traffic, with the base and drainage done right the first time.
A gravel driveway in this region has to survive what a suburban concrete driveway never faces — deep frost, a spring thaw that turns solid ground to muck, plow blades that grab surface material, and the weight of fuel and septic trucks year-round. A driveway that lasts twenty years and one that fails in its second winter are built very differently, and the difference is mostly underground.
Georgian Bay Siteworks builds driveways and private roads with our own equipment, base preparation and drainage done correctly from the start. This page covers what it takes to build one that lasts.
It starts under the surface: subgrade and base
Most driveway failures are not bad gravel — they are decisions made below the surface. The most important step is stripping topsoil, organics and roots before any base goes in; organic material left under a driveway compresses and decays into soft spots that fail with each freeze-thaw cycle. On top of the prepared subgrade goes a compacted granular base of angular crushed stone, placed and compacted in lifts so it holds under load.
Crown, drainage and culverts — sized for spring melt
Crown
The slight centreline peak that sheds water to the sides instead of letting it pool in the wheel tracks, where it turns to ice and ruts. Subtle but essential, and the core of annual upkeep.
Culverts
At the entrance and at low points along the lane, sized for the upstream catchment and the March melt — not the minimum. An undersized culvert overtops in spring and erodes the base.
Built for plow traffic and heavy trucks
A rural driveway sees plow trucks, fuel and propane delivery, and septic pumpers — not just cars. Plow blades are hard on gravel; we maintain surface depth, keep the crown so plows clear evenly, and build extra base where the heaviest trucks turn and park. Bare gravel in deep winter is not the goal — a packed, drivable surface is.
Surface gravel and annual upkeep
The surface course — typically three-quarter-minus crushed gravel — is consumed slowly by traffic and plowing, so topping it up every few years is normal, not a repair. A well-built driveway needs only a spring grading pass to re-establish crown and fill ruts, a culvert and ditch check, and periodic top-dressing — and it lasts twenty years or more.
What drives the cost
| Factor | Why it changes the cost |
|---|---|
| Length & width | More driveway means more excavation, base, gravel and culverts. |
| Subgrade condition | Organics, clay or a high water table add stripping or remediation. |
| Base depth | Heavier traffic and poorer subgrade call for a deeper base. |
| Drainage & culverts | Number and size of culverts and ditching, sized for the catchment. |
| Slope & access | Grades and tight access add time and material. |

Frequently Asked Questions
How much does a gravel driveway cost?
It depends on length, subgrade, base depth, drainage and access — not length alone. We give a firm written number after walking the route.
Do I need a permit to build a driveway?
A new entrance onto a municipal road needs an entrance permit, which sets the culvert size and location. We arrange it. Regulated lots near water may also need conservation review.
How deep should the base be?
Deep enough for the frost, subgrade and traffic — a residential driveway on good ground starts around 300mm of compacted granular, more for heavy truck use or poor subgrade.
Why does my driveway keep rutting and washing out?
Usually organics under the base, no crown, or undersized/blocked culverts. We rebuild with the subgrade stripped, a crowned base and culverts sized for the melt.
Can you build a long cottage lane or private road?
Yes — they just need more attention to drainage, mid-run culverts and crown over the full length. We walk the whole route before quoting.
How do I keep plows from tearing it up?
Maintain surface gravel depth, keep the crown so plows clear evenly, and have the operator skim rather than scrape.
What maintenance does it need?
A spring grading pass, a culvert and ditch check, and top-dressing every few years — light, predictable upkeep on a well-built driveway.
When is the best time to build?
Late spring through fall, when the ground is workable and drainage patterns are visible before material is placed.
