Driveways & Aggregate

The order that saves money

1. Confirm you can legally connect to the road. On a new access, this comes before everything. Municipalities and provincial highways authorities control where a driveway may meet a public road, and they can refuse on sight-line grounds. The entrance permit usually brings a culvert requirement with it, sized and installed to their specification. This is the item most likely to stop a rural project outright, and it's free to ask about.

2. Find out what's under it. A driveway is a structure, and the base carries it. Undisturbed, well-drained ground is the cheap case; soft, wet, organic, or previously filled ground means excavating it out, importing granular, and often laying geotextile first. This single unknown moves driveway budgets more than the choice of surface does.

3. Decide where the water goes. An impermeable surface has to shed water somewhere that isn't your foundation or your neighbour's lot. On flat sites that means grading, swales, or a culvert. Permeable surfaces avoid the runoff at a higher upfront cost and with an ongoing maintenance obligation.

4. Choose the surface last, once the first three are known. The surfaces span roughly a factor of four per square foot, so on a long rural laneway the choice can exceed the cost of the building it serves — but choosing it before you know your base condition or drainage requirement means pricing the wrong thing.

5. Measure the whole paved area, not the lane. Turnarounds, second-vehicle parking, the widened apron at the garage doors, and room for a delivery truck to turn routinely add 20–40% to what people first estimate.

Where driveway budgets go wrong

• Buying the surface and skimping the base. The most common cause of asphalt that alligators within a few years, or a concrete slab that cracks through in its first freeze-thaw. It's invisible once the job is finished, which is exactly why it's where cheap quotes cut.
• Comparing quotes that specify different base depths. Two driveway prices are only comparable if the excavation and granular scope match. They frequently don't.
• Ignoring maintenance as a cost of ownership. Gravel needs top-ups and regrading, asphalt needs sealing, pavers need joint sand, permeable surfaces need vacuum-sweeping. The cheapest surface to install is rarely the cheapest to own.
• Forgetting snow. A driveway with nowhere to push snow becomes a driveway you pay to have trucked away, every winter.
• Choosing loose gravel on a slope, where it migrates downhill and washes out in heavy rain.
• Overlooking the boulevard. The stretch between your property line and the road often has its own rules, inspection, and sometimes an approved-contractor requirement.

If the driveway is part of developing raw land rather than a standalone job, price it alongside the clearing, servicing, and grading it usually arrives with in the Lot Development Estimator.
