Replacing a Driveway: the Drainage Question

There is one line on a replacement quote that most homeowners never ask about, and it is usually the line that explains why they are replacing anything at all.

Updated August 2026 · Libertyville Concrete

Ask about a driveway replacement and the conversation goes to concrete: how thick, what finish, how much. Almost nobody asks where the water will go, which is unfortunate, because water is what took the last one apart.

A replacement is the only occasion in twenty or thirty years when that is fixable. Once the new slab is down, the fall of your driveway is settled again for its entire life.

What the published figures say it costs

HomeGuide prices the things that happen before concrete arrives:

• Grading - $3 to $8 per square foot, or about $700 to $2,500, described as ensuring proper drainage and a stable foundation
• Removing the old driveway - $2 to $6 per square foot
• Clearing vegetation and debris - additional, where the site needs it

Grading is the interesting one. It is a line item with a published price, a stated purpose, and an almost complete absence from the quotes homeowners actually receive.

Reading your old driveway for the cause

Before deciding what to buy, spend ten minutes working out what went wrong. The evidence is usually visible, and it is rarely in the cracks themselves.

Where does water stand? A puddle that is still there the day after rain marks a low point that should not exist. That water sits, soaks in at the joint, freezes, and expands.

Which way does the driveway fall? Toward the street is right. Toward the garage is a problem you have been living with. Flat is the worst of both, because water goes nowhere in particular and finds its own route underneath.

Where does the damage cluster? Break-up concentrated at one edge, along the garage, or at the low corner is drainage telling you plainly. Damage spread evenly across the whole surface is more likely wear and salt.

What happens to your downspouts? A downspout discharging onto or beside the driveway delivers a roof's worth of water to one spot repeatedly. It is a cheap thing to redirect while the slab is off, and an expensive thing to ignore. Worth knowing that the Village lists downspout extensions among the work an Engineering Permit covers, so raise it with whoever is handling the paperwork rather than treating it as a weekend job.

Why this is the moment and not any other

Correcting a fall means moving earth, and moving earth means the concrete above it has to be gone. During a replacement it already is. The machine is on site, the spoil is already being hauled, and the ground is open and visible for the only time in the driveway's life.

Doing the same work later, as a standalone job, means demolishing a driveway you just paid for. That asymmetry is why grading belongs on the quote now even though it feels like an optional extra, and why declining it is a decision with a long tail rather than a saving.

What to put to whoever is quoting

Two questions, and the quality of the answers tells you a great deal.

The first is simply which way will the finished driveway fall, and where will the water end up. Somebody who has thought about the job answers immediately and points. Somebody who has priced a slab looks at the ground for the first time.

The second is what do you think caused this one to fail. A contractor with no theory is a contractor who is about to rebuild the same conditions.

The Libertyville complication, and it is a real one

Grading and drainage work brings the Engineering Division into your project here. So does any change to impervious surface area, which is the technical way of saying a larger driveway. Both are permit territory.

That is not an argument against doing the work. It is an argument for raising it at the quoting stage, because a replacement that stays inside its existing footprint and keeps its existing fall is administratively simple, while one that widens the driveway or alters where water runs is a different conversation with the Village. Discovering which one you are in halfway through is the expensive version, which is why, when we replace a driveway in Libertyville, the permit question is settled on the site visit before a number is written down.

Worth remembering too that the apron at the street is built to the Village's own specification and sits in the public right-of-way. The Libertyville driveway cost page sets out what that involves, including a route for asking the Village to contribute toward apron replacement.

Where the rest of the money goes

Demolition and haulage are charged on weight, because that is how disposal facilities bill and a driveway is several tons of dense material. Steel cast into the old slab slows it further. An old asphalt drive comes off lighter and quicker, which is one of the places the two materials stop costing the same thing even before anything new is poured.

Then the sub-base, where precise pricing is impossible up front because the concrete is sitting over the thing that needs assessing. A good bid deals with that by carrying a named allowance and spelling out the conditions that would use it up. Quiet on the point now tends to become a variation later.

Afterwards

Fresh concrete has a first year unlike any that follow, and the bag most households reach for in December is the wrong one. Details sit on the driveway cost page.
