A Concrete Company That Knows Katy
Most homes with a Katy address are not inside the City of Katy. The city covers about 15 square miles where Harris, Fort Bend, and Waller counties meet. Greater Katy is much bigger. It roughly follows the 181-square-mile Katy school district and takes in Cinco Ranch, Grand Lakes, Nottingham Country, and many other communities. For a concrete contractor in Katy, that matters on day one. Your address decides who issues the permit, which HOA reviews the plan, and which flood rules apply.
The ground matters just as much. Katy sits on flat coastal prairie, and water moves across it slowly. The soil that carries the Katy name has a sandy top layer over a tighter clay loam that holds water. We build for that with a compacted base, steel rebar, and a real slope on every slab. Our base is in Pinehurst, so we drive to you, walk the site, and give you a written quote.

Concrete Services in Katy
Katy mixes brand-new homes with subdivisions from the 1970s and 1980s, so foundations, driveway replacement, and repair lead our list here. See all concrete services.
Foundation Repair in Katy
Homes keep going up across Greater Katy on wet prairie ground. We pour slab-on-grade and pier-and-beam foundations for new builds and additions, and we repair and level slabs that have already moved.
Foundation servicesConcrete Driveways in Katy
Nottingham Country and Memorial Parkway were built in the 1970s and 1980s, so many original driveways there have been down for decades. We replace them 5 to 6 inches thick with 4,000 PSI concrete and rebar on 18-inch centers.
Driveway servicesConcrete Repair in Katy
Not every crack needs a new slab. We replace broken sections of driveways, patios, and walks, and we fix low spots where water sits on a flat Katy lot instead of running to the street.
Repair servicesConcrete Patios in Katy
Flat backyards need a patio that is sloped away from the house on purpose. In communities with design rules, like Cinco Ranch, we help you put together the plans your HOA asks for before we pour.
Patio servicesEpoxy Flooring in Katy
Katy's hot, humid summers are hard on a bare garage slab. We clean and prep the concrete, then apply epoxy, polyaspartic, or metallic coatings for garages, shops, and commercial floors.
Epoxy servicesStamped Concrete in Katy
Stamped, stained, and exposed aggregate finishes dress up patios, walkways, and pool decks. In HOA neighborhoods, we pick patterns and colors that fit the look your association allows.
Decorative concrete servicesSidewalk Repair in Katy
Inside city limits, the City of Katy requires a permit for sidewalk work. We pull it, then replace lifted or broken panels. We also build walks and ADA ramps for HOAs and businesses.
Sidewalk servicesRetaining Walls in Katy
Katy is flat, so most walls here are short. They hold soil at pond and ditch edges, raised beds, and patio steps. Each one gets drainage behind it so trapped water does not push it over.
Retaining wall servicesConcrete Parking Lots in Katy
Businesses along I-10 and Mason Road need lots that shed heavy rain. We pour and repair concrete parking lots, dumpster pads, and curbs, sloped so water runs to the drains.

What the Katy Prairie Means for Your Concrete
- 01
The Soil Named After Katy
The USDA names a soil series after Katy, and its sample site sits near Fulshear, just off FM 1463. The top layer is fine sandy loam. About 18 to 30 inches down, it turns to a tighter clay loam that water moves through slowly. In wet spells, water can sit on that layer just a few inches below the surface. Local history also says the thick clay made early settlers slow to come. So we strip soft topsoil, compact the base, and add steel rebar. If we find heavier clay on your lot, we plan for it before we pour.
- 02
Flat Ground and a Flood History
Rain drains off the Katy Prairie slowly. In big storms, Cypress Creek can overflow and send water south toward Addicks Reservoir. The Army Corps of Engineers built Addicks and Barker reservoirs in the 1940s. During Hurricane Harvey in 2017, water held behind them flooded homes upstream in Cinco Ranch Equestrian Village, Canyon Gate, and Mayde Creek Farms. The ground is also sinking. One Katy monitoring station recorded more than a foot of subsidence from 2007 to 2025. Over time, that can flatten the grade on a lot. We set every slab to drain away from your home.
- 03
Permits: City, County, or HOA
Inside city limits, the City of Katy requires permits for driveways, sidewalks, and patios. Outside them, the county takes over. Harris County requires a permit for any driveway built in the right-of-way between your lot and the street. Unincorporated Fort Bend County requires one for a new slab of 400 square feet or more, or a driveway that ties into a county road. In a mapped flood zone, both counties need a permit for paving. Parts of Cross Creek Ranch fall inside Fulshear city limits. Cinco Ranch adds HOA design review. We check it all and pull the permits.

Homes Built in Waves
Katy homes went up in waves. Nottingham Country and Memorial Parkway were built in the 1970s and 1980s. Census data says the typical home in Cinco Ranch was built around 1997, and in the City of Katy around 2003. The city itself grew from about 8,000 people in 1990 to nearly 22,000 in 2020. So we see two kinds of work here. Older subdivisions need worn driveways and walks replaced. Newer homes need patios, extensions, and slabs for additions. Either way, we plan the joint where new concrete meets old.
Neighborhoods We Serve in Katy
We work in the city and across Greater Katy. In Old Towne Katy, homes sit near the historic town square and the J.V. Cardiff & Sons Rice Dryer on First Street. Work on it began in 1943, and it was the first concrete rice dryer in Texas. Its 177-foot tower is still the tallest structure in the Katy area. East of the city, Nottingham Country sits between I-10, Fry Road, and Westgreen Boulevard. Memorial Parkway lines the Mason Road corridor. Cinco Ranch has more than 15,000 homes, mostly in Fort Bend County.
From Pinehurst, we take State Highway 249 to the Grand Parkway, which runs south to I-10 at Katy.

What Affects Concrete Cost in Katy?
We don't publish set prices, because two Katy jobs of the same size can cost very different amounts. The biggest swings come from what is under the slab, what has to come out first, and what paperwork your address needs. Our quote form lists budget ranges from under $5,000 to $40,000 and up. The on-site estimate is free, and your written quote spells out each step.
Tearing Out an Older Slab
Replacing a 1980s driveway in a neighborhood like Nottingham Country means breaking out the old concrete and hauling it off first. Bigger and thicker slabs take more time and more truck loads.
Base Prep and Drainage Fixes
Soft, wet subsoil may need to be dug out and replaced with compacted fill. A lot where water pools may need new grading before we pour. We price that work up front, not halfway through the job.
Permits and HOA Review
A City of Katy permit, a county right-of-way or floodplain permit, and HOA approval can each add time. In a Harris County flood zone, paving can need an engineer's drawings. We tell you what your address needs at the estimate.

Concrete Project Works
Start to Finish
Here is how a typical Katy job runs, from the first visit to the final walkthrough.
Free On-Site Estimate
We come to your property, measure, and check where water goes after rain. We also confirm whether the City of Katy, Harris County, Fort Bend County, or Fulshear handles your permit, and whether your HOA needs plans.
Demo & Removal
If you are replacing old concrete, we break it out and haul it away. Then we dig out any roots or soft, wet spots we find under it.
Grading & Forming
We strip loose sandy topsoil, compact the base, and set forms with a steady fall away from the house. On a flat prairie lot, that slope is what keeps water off your slab.
Reinforce With Rebar
Driveways get steel rebar on 18-inch centers. The steel helps the slab hold together if the clay loam below gets soft in a wet season.
Pour & Finish
We pour driveways 5 to 6 inches thick with 4,000 PSI concrete. Then we finish with a broom, stamped, or exposed aggregate surface. We watch the forecast and plan around heavy rain.
Cure, Seal & Walkthrough
The slab cures, we seal it when the finish calls for it, and we walk the job with you. If we pulled a permit, we make sure the final inspection is on the schedule.

Concrete Questions From Katy Homeowners
Straight answers from our crew. Still have a question? Call us and talk to a real person.
Get a Free EstimateDoes the City of Katy require a permit for a driveway or patio?
Yes, inside city limits. The City of Katy requires permits for driveways, sidewalks, and patios, along with most other building work. Permits go through the city's Permit and Building Services division, which takes applications online. Many homes with a Katy address are outside the city, though. In that case, Harris, Fort Bend, or Waller County rules apply instead, and your HOA may have its own review. We check your address at the estimate and pull the permit when your job needs one.
My address says Katy, but I live in Cinco Ranch. Whose rules apply?
Cinco Ranch is outside any city limits, and most of it is in Fort Bend County. There, the county requires a permit for a new slab of 400 square feet or more, for a driveway that connects to a county road, and for work in a mapped flood zone. Part of Cinco Ranch is in Harris County, where any driveway built in the right-of-way between your lot and the street needs a county permit. Cinco Ranch also has property associations that set and enforce design rules, so plan on HOA approval for most visible work. We sort this out before we quote.
Why does concrete crack on Katy-area soil?
Much of the Katy area sits on loamy prairie soil with a tighter clay loam layer below it. Water moves through that layer slowly, so the ground can stay soft after heavy rain and then dry out in summer heat. When the base under a slab is wet or weak, the concrete can settle and crack. We compact the base, reinforce with steel rebar, and slope every slab to drain. For homes that have already moved, we offer foundation repair, including leveling and pier work. We also pour new slab and pier-and-beam foundations for new homes and additions.
Does living near the Addicks or Barker reservoirs change my project?
It can. Some neighborhoods near Katy sit inside or next to the reservoirs' flood pools, and homes there flooded during Hurricane Harvey in 2017. If your lot is in a mapped flood zone, both Harris County and Fort Bend County require a permit for paving and grading. In Harris County, that can mean drawings from an engineer. We also look at where new concrete will send water, so a patio or driveway does not push runoff toward your house or your neighbor's. Give us your address and we will check the flood map first.
How far is Katy from your base, and is the estimate free?
Our base is in Pinehurst, about 28 miles from the City of Katy in a straight line. The drive runs down State Highway 249 and the Grand Parkway to I-10. We don't have a Katy office, so we come to you. The estimate is always free and always done on site. We measure, check your drainage and soil, and give you a written quote. We reply to inquiries within one business day, and we work every day from 8:00 am to 6:00 pm.
What is the best time of year to pour concrete in Katy?
We pour all year in Katy. Winters here are mostly mild, so cold is rarely the problem. Rain and summer heat are. Heavy rain can soften the base on a flat lot, so we wait for the ground to firm up. In summer, heat dries fresh concrete fast, so we plan the pour and the cure to keep the surface from drying too quickly.
