A crack in a driveway is the slab telling you something. Some are shrinkage lines that open in the first year and then stay put. Others widen, step up at one edge, or let water run beneath the surface, and those are the ones that turn a repair into a replacement if they sit too long. We repair concrete driveways across Decatur, and on every property the first job is working out which kind of crack we are looking at.
We start with the whole driveway, not just the line that caught your eye. We check whether the slab has settled, whether the crack runs through the reinforcement, and where water goes when it leaves the surface. Every site is tested individually before work starts. Then the crack is cleaned out, opened up where it needs it, and filled with materials chosen for how much that section of concrete still moves. Short cracks can be quick. Long ones take patience.
Most failed repairs we see came from filling a crack without asking why it opened. A bead of sealant over a moving crack looks fine for a season, then splits again along the same path. With about 55 inches of rain a year, a crack left open keeps feeding water under the slab, and that is usually when the edges begin to drop. Getting it right means fixing the cause along with the line on top. Call for a free estimate.
A slab quote from us is built on your site, not a chart. We walk the ground, test the soil (every site gets tested before work starts, because it changes from lot to lot), and measure how much grading and compacted gravel base the pad needs. The written estimate spells out forming, rebar or wire mesh, the concrete mix and the finish, so you can see what each line covers. Call for a free estimate on the slab you actually need.
Driveways fail from the bottom up, so most of our time goes into the part you never see. We dig out soft spots, compact a gravel base, and set rebar on chairs so it sits in the middle of the slab instead of on the dirt. The apron at the street gets extra thickness, since that is where heavy vehicles turn. With about 55 inches of rain a year, we slope every driveway to carry water away from the garage. Finishes run from broom to stamped.
Interior floors call for different habits than outdoor work. Basements, garages, shops and small commercial spaces get a vapor barrier under the slab, a trowelled finish that stays flat, and saw cuts placed where cracks would want to form anyway. We can leave the surface smooth and sealed, or grind and polish it so it handles foot traffic without a coating. Decorative stains and epoxy go down after the concrete has cured, never before, because trapped moisture lifts coatings off the floor.
Not every cracked slab needs to come out. Hairline shrinkage cracks can be routed and sealed. A slab that has sunk or heaved tells a different story, usually a washed-out base or water running underneath. We find the cause before we touch the surface, because patching over a void just moves the crack a few feet. When a section is too far gone, we saw-cut it out, rebuild the base, dowel the new pour into the old slab, and match the existing finish as closely as the concrete allows.
Sidewalks look simple, which is exactly why so many of them buckle and trip people. We compact the base across the full width of the walk, pitch the surface slightly so rain runs off instead of pooling, and tool control joints close enough that cracks land in them rather than across a panel. A broom finish gives grip when it is wet. Where a walk meets a driveway or a step, we add an expansion joint so the two slabs can move without pushing against each other.
A crack in a driveway is a symptom. The slab moved, water got under it, or the base below gave way, and filling the line on the surface does nothing about any of that. We look at why the concrete split before we decide how to repair it. Sometimes a routed and sealed crack is the right answer. Sometimes the section has settled or lifted and needs to come out, with proper reinforcement and a compacted base under the new pour.
Every job starts on site. We walk the driveway with you, check how water runs off it and where it pools, and test the ground under the damaged area, because conditions change from one property to the next. Then we tell you what we found and what we would do about it, in plain terms. If a repair will hold, we say so. If the slab needs replacing, we say that too, and we explain why. Nobody gets pushed toward the bigger job.
Most repeat cracks come from the same mistakes: a patch that sat on a wet base, a sealant that could not flex, or a joint left out where the slab needed room to move. The area sees about 55 inches of rain a year, and water finds any gap left open. So we clean and dry the crack properly, use materials rated for the movement, and cut control joints where they belong. For a free estimate on your driveway in Decatur, call us.
Most driveway cracks need one of a few repairs, and the crack itself tells us which. Hairline shrinkage cracks that have stopped moving get cleaned and filled with a thin sealer that soaks down into the gap. Cracks that open and close with temperature get routed out and filled with a flexible polyurethane sealant, because a rigid filler in a moving crack just breaks again beside itself. Where a slab has settled or split through its full depth, we look at structural epoxy injection, or at cutting out the failed section and pouring new concrete with fresh reinforcement tied into the old.
Every repair starts with looking, not with a product. We measure the crack width, check whether the two sides still sit level, and watch where water goes when it runs off the driveway. The site is tested before any work begins, since what sits under the slab decides whether a surface repair will hold. Then the crack is ground clean, blown out and dried. Sealant bonded to dust lets go quickly. On stamped or decorative surfaces we match color and texture as closely as the existing concrete allows, and we are straight with you about how close that is.
Water is what turns a small crack into a broken slab. Decatur gets about 55 inches of rain a year, and every bit of it that finds an open crack can wash fine material out from under the concrete and leave a void behind. A sealed crack with a downspout still emptying against its edge is only half a repair. So we treat drainage, control joints and the base as part of the same job. Sometimes the right answer is a short section of new slab instead of filling the same crack twice, and we say so.
Two driveways the same size in Decatur can carry very different quotes, and most of the reasons are visible from the curb. It usually comes down to what is already in the ground, how we reach it, and where the water goes.
| What changes the price | Which way | Why |
|---|---|---|
| Hairline cracks on a slab that still sits level | costs less | A sound slab with fine cracks is repair work. We clean, rout and seal them. |
| Panels that have sunk, lifted or broken into pieces | costs more | Once a section has moved, a patch will not hold. That panel comes out and gets repoured. |
| Old concrete or asphalt that has to come out first | costs more | Breaking, loading and hauling the old surface is labor and disposal before any new work starts. |
| A truck can back straight up to the pour | costs less | Chute delivery is quick. A narrow side yard, low wires or a steep approach can mean a pump or wheelbarrows. |
| Thicker slab, or rebar in place of wire mesh | costs more | Heavier vehicles such as a work truck or camper need more concrete and more steel under them. |
| Water pooling on the slab or running under its edges | costs more | With about 55 inches of rain a year, grading or a drain gets fixed first, or the new crack follows the old one. |
| Tree roots close to the driveway edge | costs more | Roots lifting the slab have to be cut back or bridged before any repair will last. |
| A stamped or decorative finish that has to match | costs more | Matching an existing pattern and color on a repaired section takes extra time and materials. |
When you compare bids, line them up on the same points: slab thickness, rebar or mesh, whether tear-out and haul-away are included, and what is being done about drainage. Ask whether the base gets checked, too. We test every site before work starts. A lower number that leaves one of those out is usually quoting a different job.
We split the job into sections so part of the lot, and at least one entrance, stays open while the rest is closed off. Work areas get cones, barricades and clear signs that route customers and staff around them. Pours can be set for the hours your business is closed or quiet. Fresh concrete stays fenced until it can carry traffic. The order of work is agreed with you before the first cut.
It depends on what sits under the surface. Hairline cracks, flaking and a worn finish on a slab that is still level can usually be repaired, and a resurfacing coat evens out the look. When sections have sunk, lifted, or broken into pieces that rock underfoot, the base has failed. Patching that only hides it for a while. Replacement is the honest answer there, and we check the slab and the ground beneath it before recommending either.
Don't take any contractor's word on this, ours included. Ask for the documents in writing and check each one with whoever issued it: the licensing board, the insurance carrier, the bonding company. On commercial work, your landlord, property manager or general contractor may also need certificates naming them before anyone starts. Checking takes a few phone calls. Skipping it is how property owners end up carrying someone else's risk.
The one who looks at your ground before quoting. A good foundation contractor explains the footing, the reinforcement and the drainage plan in plain terms, then puts all of it in the written scope. Be wary of anyone who prices a foundation from the driveway without walking the lot. We would rather you hold us to that standard than take our word for anything. Get more than one estimate and notice who answers your questions without hedging.
Every lot answers that differently. Slab-on-grade suits flat, well-drained ground and is the simplest to build. A crawlspace makes sense on a gentle slope, or where you want easy access to plumbing later. A basement fits a steeper lot where the grade already falls away from the house. The right choice comes from the site itself, so we test the soil and study the slope on every property before recommending one.
Two walls of the same height can be very different jobs, so we don't put a figure on one we haven't seen. Length matters most. After that comes what the wall is holding back, how water will drain out from behind it, and whether a truck can reach the spot. Drainage stone, weep holes and a proper footing go into every wall we build. Call for a free estimate with the length and a few photos of the slope.
