Concrete Driveways Knowledge Quiz

Expect roughly 8 to 15 per square foot installed for a standard gray driveway, including subgrade prep, forms, and pouring. Plain broom finish is at the low end; decorative work runs higher.

Size, site access, slab thickness, finish choice, reinforcement, and whether the old driveway is demolished are the big ones. Steep or tight sites where a truck cannot reach add pump and labor costs.

Stamped, exposed aggregate, or colored finishes typically add 4 to 10 per square foot, pushing the total to 12 to 20 per square foot installed. The premium buys texture and color plus a sealer that needs periodic reapplication.

Concrete lasts 25 to 30 years with almost no maintenance. Asphalt costs less upfront, about 3 to 5 per square foot, but needs resealing and repaving every 15 to 20 years. Pavers are repairable piece by piece but joints need sand and weed control.

Only if you park heavy vehicles like trucks, RVs, or equipment on it. For standard passenger cars, a 4-inch slab on a compacted base with proper reinforcement is the industry norm and saves money.

Choose concrete when you want 25 to 30 years of life, better heat tolerance, and a cleaner look. Asphalt is cheaper upfront and fine for large rural drives, but it softens in heat, stains easily, and wears out sooner.

Pavers suit curved layouts, areas that need individual unit replacement, and higher-end landscaping because damaged pavers can be swapped out. Concrete wins on large flat areas where you want a continuous, low-cost surface.

For a standard 4-inch slab, welded wire mesh with fiber reinforcement is typical. Rebar is the better choice for 5-inch-plus slabs, heavy vehicle loads, or large pours where the extra steel controls cracking.

A broom finish is dragged with a broom for a slip-resistant texture and is the standard, budget-friendly choice. A stamped finish presses patterns into the surface for a decorative look, costs more, and must be sealed.

Control joints create planned weak points so cracks form in straight lines instead of randomly. They are tooled or saw-cut within 24 hours of pouring, spaced roughly every 10 to 12 feet and at inside corners.

Look for a state license where one is required, current general liability and workers comp insurance, and several years of driveway-specific experience. Ask for references and verify their insurance certificate directly with the agency.

Ask about crew size, days on site, slab thickness, reinforcement type, joint spacing, cure time before driving on it, and whether demolition of the old driveway is included. Get every answer in writing in the bid.

Most municipalities require a permit, especially when the driveway crosses the sidewalk, apron, or right-of-way. Check with your local building department before signing a contract so the contractor can pull the permit.

Get at least three itemized quotes and compare them line by line on thickness, reinforcement, finish, and demolition scope. The cheapest bid usually deletes something, so make sure each bid includes the same work.

Ask for a certificate of insurance and call the agency listed to confirm the policy is active and covers the dates of your project. Verify both general liability and workers comp, since an uninsured injury can become your liability.

Keep all vehicles off for at least 7 days, and ideally 14 for heavier cars and trucks. Concrete reaches full design strength at 28 days, so treat it gently in the first month.

The contractor should excavate 6 to 8 inches, install and compact a gravel base, and set forms level with the planned finish height. Pouring directly on unprepared dirt is the most common cause of early cracking and settlement.

Yes. After the slab cures for 28 days, a penetrating sealer protects against salt, oil, and de-icing chemicals. Plan to reapply it every 2 to 3 years, more often in harsh winters.

Contractors typically offer a 1 to 5 year workmanship warranty covering cracking and surface defects, separate from the ready-mix plant's material warranty. Ask specifically how cracks are handled and get the policy in writing.

Look for uniform color, straight and clean edges, joints cut at proper spacing, and no birdbaths where water pools. Flood the surface after cure to find low spots, and flag any trowel marks or discoloration before final payment.

The classic traps are a thin 3-inch slab, no rebar or mesh, no gravel base, and concrete poured directly on dirt. Ask for the thickness and reinforcement in writing so the low bid cannot quietly delete them.

Demolition and hauling the old slab, subgrade repairs, permit fees, concrete plant distance surcharges, and weekend or overtime labor are common add-ons. Confirm which of these the quoted price already includes.

Slabjacking, or mudjacking, lifts a slab that has settled but is otherwise sound, typically running 3 to 6 per square foot. Repour when the slab is badly cracked, spalled, or the base has washed out.

The usual causes are a weak or uncompacted subgrade, joints spaced too far apart, loading the slab too early, or pouring without reinforcement. A year-one crack that follows a joint or corner is usually a construction issue, not normal shrinkage.
