Concrete Driveway Installation in Portland, OR

A standard passenger-vehicle driveway is poured at a minimum of 4 inches. If you regularly park heavier vehicles, RVs, or equipment, 5 to 6 inches with additional reinforcement is the better call. We size the pour to what you actually plan to drive on it.

Concrete generally lasts longer — often 25 to 40 years versus 15 to 20 for asphalt — and does not need periodic sealing. Asphalt costs less upfront and can be a reasonable choice on a tighter budget. We walk through the tradeoffs so you can decide based on your timeline and budget, not just the sticker price.

Early cracking is usually tied to inadequate base compaction, control joints that were spaced too far apart, or a pour that went down in poor weather. In Portland Metro, water infiltration into an already-cracked base makes the problem worse each winter. An on-site assessment determines whether the cause is fixable with repair or points to a base problem that needs a full redo.

Concrete typically reaches enough strength for light foot traffic within a day or two, but we recommend keeping vehicles off a new driveway for about a week and avoiding heavy loads for closer to a month while it continues to cure and gain strength.

Four inches is the normal residential standard and it is genuinely adequate for passenger vehicles on a properly prepared base — the base matters more than the extra inch. It stops being adequate the moment the duty changes: an RV, a loaded box truck, a trailer with a concentrated tongue load, or regular equipment traffic calls for 5 to 6 inches. On reinforcement, wire mesh and rebar are not interchangeable. Mesh helps hold a crack tight after it forms; rebar adds real load-carrying capacity and matters most under heavy or point loads; fiber in the mix reduces shrinkage cracking but is not a structural substitute for either. Plenty of sound residential driveways have no rebar at all, which is why its absence is not automatically a red flag — but thickness and reinforcement are also the easiest place for one bid to be quietly cheaper than another, and you cannot see either one after the pour. Ask for both in writing.

When the budget will not stretch to concrete without cutting the base work, gravel or asphalt done properly beats concrete done thin — a 4-inch slab on an inadequate base fails faster than a well-built gravel drive. Asphalt is also the better call when you need the surface in service almost immediately, or on a very long driveway where the cost gap compounds. Gravel is reasonable on rural properties where the drive is functional rather than architectural, and phasing is legitimate too: gravel now with a concrete apron at the garage, concrete later. We would rather tell you concrete is the wrong spend for your situation than sell you a compromised version of it.

Reseal when the slab is sound and the problems are cosmetic: surface staining, light scaling, or hairline cracks that aren't moving. A penetrating sealer helps keep water out, which matters in western Oregon's long wet season. Repair or replace when you see wide or growing cracks, sections that have sunk or heaved so edges trip people, widespread spalling where the surface breaks off, or water pooling against the garage or house. Sometimes the right answer is in between — replacing one or two failed sections and sealing the rest. In Portland, where the median home was built in 1966 (U.S. Census ACS 2024 5-year estimates), many driveways are original or decades old, so checking for settlement and root damage from nearby trees is worth it before you choose.
