Decide
Is Your Driveway Finished, or Just Tired?
Four ways a driveway ends around here, what each one is actually telling you about the ground below it, and a straight verdict on each. Including the case where the right answer costs a fraction of a rebuild and is somebody else's trade.
There is no price on this page. That is deliberate. Before a number is any use you have to know which of four quite different things is wrong, because two of them are cosmetic, one of them belongs to a trade we do not practise, and only one of them is genuinely a new driveway.
Work out which you have first. The replacement budgeting page is waiting if the answer turns out to be the fourth one.
Failure one: the surface has come away
What it looks like. Rough, pale, gritty. The smooth finish has gone and the stone in the mix is visible. In the worst patches small flakes lift away.
What it means. Water sitting in the top few millimetres froze and pushed the paste off. Road salt drives this hard, because it holds moisture at the surface and pushes the concrete through far more freeze cycles than the weather alone would manage. It is by some distance the most common complaint on a Kenosha County driveway and it says nothing at all about the strength of the slab underneath.
The verdict. Measure the depth, not the area. Losses confined to the skin are ugly and stable, and you can live with them or cover them. Once the loss is deep enough that the aggregate is loose under a boot heel, an overlay has nothing to grip and will fail separately within a couple of seasons. Deep and widespread means the top of that slab is done, even if the body of it is fine.
Failure two: it has cracked
What it looks like. Anything from a hairline running off a corner to an open line you could lose a coin down.
What it means. Usually nothing alarming. Concrete shrinks as it cures and moves with temperature, and it relieves that stress by cracking. Saw cuts exist to choose where. A crack that has appeared away from the cuts often just means the cuts were spaced a little far apart or made a little late.
The verdict. Two measurements decide it. If the crack is narrow enough that a fingernail will not enter, seal it and forget it. If it is wide, water is entering the base in volume and that will get worse. But the finding that overrides both is height: lay a straight edge across and look from the side. One side sitting above the other is not a concrete fault at all, and it takes you to failure three.
Failure three: a section has dropped
What it looks like. The concrete is intact and unbroken, but a panel or a run of panels sits lower than it used to. Often near the garage, often where a trench was once dug, often where water has been discharging for years.
What it means. The slab is fine. The material beneath it is not. Something has washed out, consolidated or was never compacted properly to begin with, and the concrete has simply followed it down.
The verdict, and we will be direct about it. Sound concrete that has settled should be lifted and the void beneath it filled. That is cheaper than demolition by a very wide margin, it takes hours rather than weeks, and you keep a driveway with plenty of life in it. It is not work we do. We pour concrete, we have nothing to gain from sending you to a lifting contractor, and that is precisely why this recommendation is worth reading.
The limit is easy to state: lifting works on concrete that is still in one piece. Raise broken concrete and all you have is broken concrete at the right height.
Failure four: it is coming apart
What it looks like. Cracks that interconnect rather than run singly. Edges and corners crumbling. Joints spalling out into gaps. Panels rocking underfoot. Several of the first three failures at once, in more than one part of the driveway.
What it means. The slab has stopped behaving as a structure. This is the one that is genuinely finished, and by the time it reads this way the cause is almost always below: inadequate or contaminated base, water that was never given anywhere to go, or a slab poured thinner than the loads it went on to carry.
The verdict. Replacement, and replacement that spends real money on what goes underneath. Rebuilding the same slab on the same ground buys you the same failure, which is why the ground correction line on a quote deserves more of your attention than the concrete line does.
Then count, because one panel is not four
Once you know which failure you are looking at, the scope question is arithmetic rather than judgement. Divide the driveway into panels and count the ones needing work.
- One or two, with nothing stepping and the rest sound: cut them out and replace them. Expect the new concrete to sit lighter than its neighbours for a season or two.
- Roughly a third or more: you are paying for the same mobilisation, the same disposal run and the same crew day repeatedly, on a driveway that has already told you what it intends to do next.
- Any amount of stepping: solve the ground question before deciding anything about the concrete.
Have somebody look at it before you decide
Four quick questions and a local concrete contractor will be in touch to set up a free on-site visit. If what you have is failure three, you will be told that, and there is no charge for being told you do not need us yet.
If it is replacement, one local thing changes your dates
The strip between the road and your property line is governed by the Village rather than by you, and the paperwork on it has to be in hand before work starts. That is a scheduling constraint rather than a large cost, but it is the one item on a driveway project that cannot be hurried, and the ordinance is unusually pointed about starting early.
What the Village requires, who is allowed to hold the permit and what the road profile outside your house changes about the design are all in the Village approach rules. When you are ready to have it measured, our concrete driveway page covers what we build and how the approach is handled.
