Concrete Patios and Patio Extensions in Sachse, Texas
Garland Elite Concrete builds concrete patios and patio extensions in Sachse, Texas, from a first slab outside the back door to a larger pour that ties into the patio a house already has. The City's flatwork rules leave patios out of its 10% cap on paved lot coverage, but a patio still needs the flatwork permit, has to drain, and can't take over the yard, since each yard must stay mostly living landscape.
Sachse sits on State Highway 78 and the President George Bush Turnpike, about a mile north of Firewheel Town Center. We serve back yards all over it: Woodbridge off Woodbridge Parkway and Clubhouse Drive, Hudson Crossing and Jackson Meadows along Miles Road, the Heritage Park subdivision on Hudson Drive, and the streets around the 147-acre Muddy Creek Preserve on Pleasant Valley Road.

A railroad stop that became a young suburb
The settlement was formally established in 1886, when William Sachse donated right-of-way to the Gulf, Colorado and Santa Fe Railway in exchange for naming the station after him, according to the Handbook of Texas. The City's history adds that the depot signs read "Saxie," and that by the late 1920s onions were competing with cotton as a major cash crop. Sachse incorporated in April 1956 with 250 people and by the 1980s had become a residential suburb of Garland.
Most of its houses are far newer than that history. The Census Bureau's 2020–2024 survey gives a median year built of 2005, with about 67% of housing units built in 2000 or later and 1,088 in 2020 or later. About 84% are single-family detached, and about 85% of occupied homes are owner-occupied. The population went from 27,103 in the 2020 Census to an estimated 32,834 on July 1, 2025.
Subdivisions by their screening walls
The City's screening wall inventory gives a rough timeline: Hudson Crossing Phase 1 on Miles Road in 1998, Woodbridge Phase 1 on Clubhouse Drive in 1999, Jackson Meadows Phase 1 on Miles Road in 2003, Heritage Park on Hudson Drive in 2013, and Woodbridge Phase 20A walls on Woodbridge Parkway and Cody Lane in 2017 and 2018. Those are wall dates, not house dates, but they show Woodbridge still being built out in 2017–2018.
Estate lots
The city's comprehensive plan describes Estate Residential areas as having larger lots with custom homes and accessory structures, and the R-39 zoning district covers lots of 39,000 square feet or more.

(945) 441-5958Patio thickness, slope and joints
A patio is generally poured at least 4 inches thick, or 5 to 6 inches where it will carry a hot tub or outdoor fireplace. The City's flatwork procedures don't set a patio spec; instead, the site plan for the permit has to state the thickness, rebar size and spacing, and concrete PSI, so those choices are settled before the pour.
Getting water away from the house
A good exterior slope is 2%, a ¼-inch drop per foot, so a patio reaching 10 feet from the house drops 2½ inches. Textured or stamped surfaces drain more slowly, because water collects in the pattern. Sachse's own rule is short: all flatwork must be sloped or graded to drain, and none may create a drainage problem.
Joints and a non-slip finish
The NRMCA spaces contraction joints no more than 24 to 36 times the slab thickness, about 10 feet on a 4-inch slab, and uses isolation joints to separate a patio from sidewalks, stairs and other fixed points so each can move on its own. For exterior patios it calls for a broom texture.
- Contraction joint about every 10 ft on a 4-in. slab (NRMCA)
- Broom texture for a non-slip surface (NRMCA)
- 4 in. patio slab; 5 to 6 in. under a hot tub
- Rebar size and spacing stated on the permit site plan (City of Sachse)
- Graded so the patio drains away from the house (City of Sachse)

(945) 441-5958Extending the patio you already have
An extension is built much like a new patio. Nationally, a concrete patio extension runs $4 to $30 per square foot, the same as a new patio, and it still needs grading and a sand or gravel base.
Where new concrete meets old, the rules get specific. Sachse's Residential Construction Information Packet requires dowels at 18 inches on center, or expansion material, where new concrete meets existing sidewalks and driveways. The American Concrete Pavement Association sizes isolation joints between old and new pavement at ½ to 1 inch wide, with filler running the full depth.
How far a patio can spread
Patios don't count toward the 10% paving cap, but a home must still keep the majority of each yard in living landscape or an alternative the landscape ordinance allows. No flatwork may sit within 1 foot of a property line, except required driveways.
Adding a patio cover
An attached patio cover needs its own building permit. The City wants its foundation plans to show the concrete thickness, the pier or footing depth and width, and how the posts or columns anchor to the slab, and it doesn't allow a cover to be anchored to brick or siding.

(945) 441-5958Flatwork permits and inspections
The City of Sachse requires a permit for every type of flatwork, whether a driveway, patio, deck or sidewalk. Permits come from the Development Services Department (469.429.4781), and fees are paid through the SmartGov portal when the permit is approved. The flatwork procedures set the fee by the City's Master Fee Schedule without quoting a figure, so ask Development Services for the current amount.
A pre-pour inspection is required. If the work reaches the city right-of-way, the contractor must give the City a $2,000.00 liability bond, and all flatwork has to comply with Chapter 3, Section 3-25 of the Code of Ordinances. Sachse builds under the 2021 International Residential Code with the North Central Texas Council of Governments amendments.
Pool decks
Pool decks come under the pool permit: Sachse requires one for any swimming pool, spa or hot tub, and "Pool Deck Steel" is one of its required inspections.

In 2026 Dallas-area figures, a concrete patio runs $1,718 to $4,095, with most homeowners spending $2,854, and installation costs $4 to $13 per square foot. Taking out old concrete first adds $550 to $1,700 on average, and leveling or regrading a hilly site $1,000 to $3,300.

(945) 441-5958Clay, rain and pour timing
The Blackland Prairie runs from north of Dallas to just south of San Antonio, and the Soil Science Society of America puts its Houston Black clay at 46 to 60% clay. The usual defenses against clays that swell and shrink are good compaction and drainage, or a structural slab that doesn't rely on the soil for support. We'll check the ground and the grade behind your house before planning the base.
NOAA's 1991-2020 normals make May the wettest month at DFW, with 4.78 inches, and July the driest, with 2.08. Concrete cures best at air temperatures between 50°F and 80°F, and the NRMCA advises avoiding the hottest part of the day, so we'll talk through timing as well as layout.

(945) 441-5958Other outdoor concrete we pour
Beyond the patio itself, we pour stamped, stained and exposed aggregate finishes, pool decks, steps and walkways, and driveway approaches, which Sachse wants 6 inches deep with #3 bars 18 inches on center, doweled into the alley or street with no expansion joint at that edge.

How a patio or extension usually comes together.
Tell us about the yard
Call or use the form at any hour, 24/7, with a rough size and what the patio will hold: a table, a grill, a hot tub.
Layout and slope
We'll talk through the footprint, thickness and fall away from the house, and where the new slab meets any concrete that's already there.
Permit and pre-pour inspection
The site plan for the City's flatwork permit lists thickness, rebar and PSI, and the steel is inspected before any concrete arrives.
Pour and finish
The slab is placed, given a broom texture or a decorative finish, and jointed.
Cure, then seal
The NRMCA says curing should start right after finishing and normally continue 3 to 7 days, and Ohio Concrete's industry recommendation holds off sealer until 30 days after placement.
