Concrete Contractors in Norman, OK

Concrete Contractors Norman builds and repairs driveways, patios, stamped surfaces, sidewalks, steps and garage slabs for homeowners in Norman, Oklahoma. Norman is the county seat of Cleveland County and, at 189 square miles, a big place to cover: older bungalow blocks around the University of Oklahoma, decades of brick-ranch subdivisions, and acreage out east toward Lake Thunderbird. Wikipedia's climate figures for the city show an average July high of 92.5 degrees, an average January low of 27.7 and about 37.65 inches of precipitation a year. Concrete contractors in Norman have to build for heat, hard rain and the ground moving underneath, in roughly that order.

Why concrete cracks and shifts here

In snowy northern states, road salt and freeze-thaw do most of the damage. In Norman the main enemy is the soil.

Clay that moves. Much of central Oklahoma sits on clay that swells as it soaks up rain and shrinks and cracks as it dries. Oklahoma State University's study of benchmark Oklahoma prairie soils (Technical Bulletin T-150) found high clay content and significant swelling potential in three of the five soils it tested, driven mainly by montmorillonite. When the ground under a slab swells unevenly, the slab lifts and cracks. When it dries and shrinks in August, edges and corners lose support and drop.

Heavy rain, then drought. Wet springs followed by hot, dry summers mean the soil goes through that cycle every year. Downspouts that dump onto a driveway edge or a patio that slopes toward the house make it worse.

Heat on pour day. At 90-plus degrees, fresh concrete loses water fast. Pour too late in the day or skip curing, and the surface comes out weak and prone to cracking.

Winter still counts. Norman only averages about 4 inches of snow, but with January lows below freezing the slab still sees freeze-and-thaw nights.

Our standard defenses:

• A compacted crushed-stone base, so the slab rests on something firm and water drains away instead of soaking the clay
• Thickness matched to the load, about 4 inches for walks and patios and more where trucks and trailers park
• Rebar set mid-slab, so a crack stays tight instead of opening into a step
• Control joints on a planned grid, so the cracks clay movement causes run straight and where we want them
• Grading that sends water away from the slab and the foundation
• Early-morning pours in summer and a proper cure afterward

What Norman's housing means for your concrete

Census figures summarized by Point2Homes put the median build year for Norman homes at 1988, but the spread is wide. Roughly a third of homes were built in the 1970s and 1980s (16.6 and 15.5 percent), and another 32 percent went up in the 2000s and 2010s. About 62 percent of housing units are detached single-family homes.

That spread shows up on the ground. Driveways and patios poured in the 1970s and 1980s have now been through 40 to 50 Oklahoma summers, and many have the classic clay-soil look: diagonal cracks off the corners, a panel by the garage that has dropped, and sidewalk squares that have lifted at the joints. In the Miller and Chautauqua historic districts, where Wikipedia dates the homes to 1903 through 1935, walks and steps are often narrow, thin and pushed around by large tree roots. Newer subdivisions on the edges of town usually have sound driveways, so the requests there tend to be patios, wider drives and side parking pads.

Norman's sidewalk and driveway rules

Norman puts more of the concrete in front of a house on the owner than many cities do. Under the city's 2023 Sidewalk Program and Policy:

• Repair and replacement of a residential sidewalk is the responsibility of the property owner next to it.
• Panels that heave or buckle more than a quarter inch count as a trip hazard, along with heavy spalling and vegetation growing in the joints.
• An owner who gets a Hazard Notice has 30 days to make the repair.
• A city sidewalk permit is required for all sidewalk construction. Fees are waived for sidewalk and curb repairs, and a contractor hired by the owner applies for an offsite construction permit.
• The 50/50 Program (the Sidewalk and Curb Replacement Participation Program) can cover up to half the cost, while funds last, on a first-come basis.

For older driveways, the city also runs a Driveway Repair Program in its Core Area for established homes with curb and gutter and a gravel or badly damaged driveway. Applications are scored after the end of April, and an application is denied if the old driveway has already been torn out. If you think you qualify, call Engineering at (405) 366-5315 before any demolition. We will hold the schedule while you apply.

Six kinds of concrete work

• Driveways: tear-outs and replacements, curb approaches, widening and parking pads.
• Patios: broom-finished, colored or exposed-aggregate slabs, plus walkways that tie them to the house.
• Stamped concrete: flagstone, slate, brick and stone patterns for patios, entries and borders.
• Sidewalks and steps: public sidewalk repairs under the city's program, private walks and poured steps.
• Garage floors and slabs: new and replacement garage floors, shop floors, shed pads and equipment slabs.
• Repair and leveling: lifting sunken slabs, crack repair, resurfacing and replacing single failed panels.

From the first call to the finished slab

Measuring visit. We walk the area, measure, check where water goes and look at what caused the old concrete to fail.

Written estimate. Each line is priced on its own. If a repair is a real option, it appears next to the replacement price.

Permits and locates. We confirm which permits your job needs with the city and request 811 utility locates. Oklahoma Natural Gas advises contacting 811 at least 48 hours ahead, not counting weekends and holidays.

Prep. Old concrete comes out, soft soil is dug out, stone is compacted and forms are set to grade.

Pour. Rebar, concrete, finish and joints, usually starting early on summer days to beat the heat.

Cure and handoff. You get a written schedule. HomeGuide's driveway guide says to give cars at least 7 days and to wait 28 to 30 days before sealing.

Storm season and outdoor work

Norman is home to the National Weather Center, and the city has seen its share of the weather the center studies: Wikipedia notes that a high-end EF2 tornado tore through the southeastern side of Norman on February 26, 2023. For concrete, spring storms mostly mean schedule changes. We do not pour with heavy rain in the forecast, because rain on fresh concrete can ruin the finish. If you are planning a storm shelter or safe room in a garage floor or yard, the City of Norman requires a permit before it is installed and asks owners to register shelters with the Fire Department at 405-292-9780. Tell us about a planned shelter before we pour a new garage floor, so the slab can be planned around it. Call (405) 442-4315 to get on the schedule.

Most of our work is in Norman itself, from the older streets around campus and downtown to the newer neighborhoods on the west and north sides and the larger lots out east toward Lake Thunderbird. We also work in the cities and towns around Norman: Moore and the south side of Oklahoma City to the north, Midwest City and Del City to the northeast, Noble and Lexington to the south, Purcell across the county line, and Newcastle and Blanchard to the west. Each city sets its own permit and sidewalk rules, and they do not all match Norman's 50/50 program, so we check the rules for your address before we price the job. Each town page covers what we found about local housing and the city's own requirements.
