Start with what the concrete is telling you

A thin crack running straight across a driveway panel is usually not an emergency. Concrete shrinks as it hardens, and a hairline that stays tight, with both edges level, is the slab doing what slabs do. The cracks worth acting on look different: one side sitting higher than the other, a gap wide enough to swallow a coin, a web of breaks spreading from one spot, or a panel tipping toward the house so rain runs back at the foundation. Those point below the surface, to a base that washed out, clay that swelled, or fill dirt that kept settling after the house went up.

Problems that start underneath need a fix that reaches underneath, which is why Columbus Concrete Repair handles them by tearing out the failed concrete and building it back. The broken slab comes out, the soft or wet soil below it is dug out and replaced with compacted gravel, and the new pour goes in with steel reinforcement, an air-entrained mix made for Ohio winters, joints placed where cracks ought to go, and slope that sends water away. Smearing new material over a slab whose base is gone only hides the symptom for a season or two.

We replace driveways, public and private sidewalks, patios, front steps and stoops, and garage floors, and we take out concrete you simply want gone. Sometimes one or two panels are the whole problem; sometimes the slab is past saving from end to end, and the estimate visit settles which. Requests come in from Columbus neighborhoods like Clintonville and Olde Towne East and from the towns ringing the city, Hilliard and Dublin through Reynoldsburg, Grove City and Canal Winchester. Send a few details about what you are seeing; a phone call follows to talk through the damage and pick a day for a visit.

Questions

Concrete repair questions, answered plainly

Why did my concrete crack or flake after the winter?

Usually because water got into it or under it and then froze. Central Ohio crosses the freezing mark many times in a typical winter, and every freeze expands trapped water, lifting slabs that sit on wet clay and popping the surface of concrete made without entrained air. Salt carried in on tires speeds the flaking. A replacement built on drained gravel with an air-entrained mix, kept free of rock salt its first winter, holds up far better.

Do I need a permit to replace a sidewalk or driveway?

Often, for whatever sits in the public right-of-way. Replacing a public sidewalk or the apron at the street usually takes a permit from the city or village, and each community around Columbus runs its own process, while work entirely on your lot frequently needs none. HOAs may want to sign off first, and before any digging, 811 is called so OUPS can mark buried lines.

What does concrete replacement cost?

It depends on what the visit finds, which is why the estimate is free and specific to your slab. The biggest factors are square footage, how thick the old concrete is and whether it holds rebar (both slow the tear-out), how much bad soil has to come out from underneath, equipment access, and whether the new slab needs thicker sections or a city permit.

Which towns do you cover?

Columbus and 31 communities around it, including Dublin, Hilliard, Upper Arlington, Worthington, Westerville, Gahanna, New Albany, Reynoldsburg, Pickerington, Canal Winchester, Groveport, Obetz and Grove City. Smaller places such as Marble Cliff, Riverlea, Lithopolis and Lockbourne are covered too, and the service areas page lists them all.

How long does a replacement take?

Most residential jobs go from tear-out to fresh concrete in one to three working days, depending on size and how much base has to be rebuilt. After the pour, plan on foot traffic in a day or two and cars in about a week. Spring through fall is the main season, with cold-weather precautions late in the year.

Can you replace only the broken sections?

Often, yes. If the damage is limited to a few panels and the rest of the slab is sound and draining correctly, those panels are sawed free along their joints and replaced, with steel dowels drilled into the old concrete to keep the edges level. Expect the new panels to look lighter at first; the difference fades but never vanishes completely.

Do you fill cracks or raise sunken slabs?

No. Columbus Concrete Repair replaces failed concrete instead of filling or lifting it, because those fixes leave the cause, a weak or washed-out base, sitting right where it was. And when a crack is only cosmetic, you will hear that it can be left alone.

Know-how

How to read the damage before you call

  • 01

    Try the coin test

    Slide a coin into the crack. If it barely enters and both edges sit flush, it is most likely shrinkage and only worth watching. If the coin drops in, or you can feel a step from one side to the other, the ground under the slab has moved.

  • 02

    Watch where rainwater goes

    After a hard rain, look at which way the water runs. A patio or walk that now drains toward the house has settled, and every storm sends water at the foundation until that slab is replaced with fall away from the wall.

  • 03

    Flaking has a deeper cause

    Scaling, where the top layer peels off in thin flakes, usually traces back to road salt, a mix without entrained air, or a surface finished while it was too wet. A slab that is scaling everywhere is near the end of its life, and new air-entrained concrete is the lasting answer.

  • 04

    A raised joint is a trip hazard

    When one sidewalk panel rides even half an inch above its neighbor, toes and stroller wheels catch on it. Tree roots and frost do most of that lifting, and some cities send owners notices asking them to fix raised public walks. Replacing the lifted panels and dealing with what lifted them ends it.

How it works

From the first look to the new slab

  1. 1

    Describe the symptom

    Use the form or call and say what you are seeing: the crack, the sunken corner, the step leaning away from the door. Rough size and location are plenty to start.

  2. 2

    Diagnosis on site

    The slab gets walked, its drainage checked and its broken edges read, and you hear plainly which parts can stay and which have to come out.

  3. 3

    Tear-out and base rebuild

    Failed sections are saw-cut and broken out, soft soil under them is removed, and compacted gravel takes its place.

  4. 4

    Pour, joint and cure

    New concrete goes in reinforced, sloped and jointed, and you get clear dates for walking on it and for driving on it.
