FAQ

Oshawa paving questions

What happens before digging starts?

Underground utilities are located first through the local one-call service, the layout and grades are confirmed, and access and parking are arranged so the work goes smoothly.

Why do driveways crack and heave?

Most cracking comes from a thin or poorly compacted base, water getting underneath, missing control joints or heavy loads. Building the base properly and managing drainage prevents most of it.

Can you replace interlock with concrete?

Yes. We remove the pavers and bedding, correct the base and pour a concrete driveway or walkway, with a decorative finish if you want one.

Can you repair my driveway instead of replacing it?

Often, yes. If the base is sound, crack filling, patching or an overlay can add years. If the base has failed, repairs won't last, and we'll tell you that up front.

Is concrete or asphalt better for a driveway in Oshawa?

Asphalt is quicker to install, flexes with frost and is easy to reseal; concrete costs more up front but lasts longer and offers more finishes. The right pick depends on budget, slope, how long you plan to stay and the look you want.

Most paving problems in Downtown Oshawa, North Oshawa and Lakeview — cracking, heaving, pooling water — trace back to a thin base or poor drainage, so that is where every job begins.

Driveway widening or a new curb cut may need a municipal permit; we tell you early if your Oshawa job needs one.

Freeze-thaw cycles and road salt are hard on paving here, so we use air-entrained concrete, a deeper compacted base and recommend sealing.

Guide

Oshawa homeowner & property guide

Is blacktop the same as asphalt?

Mostly, yes. "Blacktop" is the everyday word for asphalt pavement. Technically both are a mix of stone aggregate and bitumen; blacktop is sometimes used for the hotter, finer surface mix used on driveways and lots, while heavier asphalt mixes go on roads. For a home driveway in Oshawa, the terms describe the same thing.

Can asphalt be paved in the rain?

Asphalt should not be laid in steady rain. Water on the base or in the mat cools the hot mix too fast, stops it bonding and leaves a weak, porous surface that fails early. Light drizzle on a well-drained base may be workable, but most crews in Oshawa reschedule. Hot-mix also needs warm enough air and ground temperatures to compact properly, which is why paving around Durham Region is usually done from spring to late fall.

Asphalt vs concrete vs interlock pavers — which lasts longest?

Concrete typically lasts longest with the least upkeep when it is reinforced, jointed and built on a proper base. Asphalt is cheaper and quicker, flexes with frost and is easy to patch, but needs sealcoating every few years. Interlock pavers look great and individual stones can be replaced, yet they shift and weed over time if the base and edge restraints are poor. In Oshawa, the base matters more than the surface: any of the three fails early on a thin base.

How thick should a driveway be?

For a residential concrete driveway, 4 inches of concrete is the usual minimum, with 5–6 inches where heavier vehicles park, on a compacted granular base of roughly 6 inches or more. Asphalt driveways are commonly 2–3 inches of hot-mix over a similar compacted base. Soil, drainage and the vehicles you own in Oshawa decide the exact build-up, and we spell it out in the quote.
