Fort WorthConcrete Calculator — Yards, Bags & Cost
Calculate cubic yards, bags needed, and Fort Worth-accurate ready-mix costs for any Tarrant County concrete project — driveways, patios, pool decks, foundations, footings, garage floors & more.
The Fort Worth Concrete Calculator helps homeowners, contractors, and builders in Fort Worth, Texas estimate cubic yards, bag count, and ready-mix costs for any concrete project in Tarrant County. Fort Worth pricing typically runs $130–$168/yd for standard 3,000–4,000 PSI ready-mix — competitive with the wider DFW Metroplex market. Fort Worth's most significant concrete challenge is its Blackland Prairie expansive clay soils (Vertisols) — some of the most shrink-swell-prone soils in the US — combined with hot summers exceeding 100°F and occasional severe winter freezes like the 2021 Winter Storm Uri. Major suppliers including CEMEX, Martin Marietta, Texas Industries (TXI), and Argos USA all serve the Tarrant County market. Enter your dimensions for instant, Fort Worth-accurate results.

Fort Worth is the fifth-largest city in the US and the seat of Tarrant County, located in North Central Texas at 620 ft elevation with a humid subtropical climate. Concrete work is governed by the Texas Building Code (TBC) 2021 (based on IBC 2021) with City of Fort Worth local amendments. The defining characteristic of Fort Worth concrete work is the city's Blackland Prairie Vertisol clay soils — expansive, high-plasticity clays that shrink dramatically during dry Texas summers and swell significantly after rainfall. This extreme soil movement is the #1 cause of concrete cracking in the Fort Worth area and demands proper sub-base preparation, reinforcement, and moisture management on every project. Permits are issued by the City of Fort Worth Development Services Department.
🔵 Fort Worth / Texas Minimum Concrete Requirements
Exterior flatwork (driveways, patios, sidewalks): 3,000 PSI min; no air entrainment required in normal TX conditions — except post-2021 Uri-level freeze events where deicers may be used · Pool decks: 3,500 PSI, 4 in. min, broom finish for slip resistance · Foundations: 3,000 PSI min per TBC; 3,500–4,000 PSI recommended for Blackland clay; post-tensioned slab is the dominant system for new Fort Worth residential construction · Frost depth: 10 in. in Tarrant County — footings and piers must extend below this. Always verify with City of Fort Worth Development Services before starting any permitted project.
🏊 Fort Worth Pool Deck Concrete
Pool decks are one of the most popular concrete applications in Fort Worth's hot Texas climate. A standard 800 sq ft pool deck at 4 inches requires approximately 10 cubic yards. Use 3,500 PSI with a broom, exposed aggregate, or stamped finish for slip resistance. Decorative stamped and colored pool decks are extremely popular in Tarrant County, with installed costs of $10–$20/sq ft. Always use proper control joints around pool deck perimeters — thermal expansion in Fort Worth's 100°F+ summers causes cracking on poorly jointed slabs.
🌡️ Fort Worth Hot-Weather Concrete
Fort Worth summers regularly hit 100–110°F in July and August, making hot-weather concrete procedures critical from May through September. Per ACI 305, schedule all large pours before 8 AM, request a Type B retarder admixture from your supplier, pre-wet the subgrade and forms before placement, and begin curing with wet burlap or a white-pigmented curing compound immediately after finishing. Fort Worth's dry summer heat combined with low humidity on westerly wind days accelerates moisture loss and plastic shrinkage cracking dramatically.
🌧️ Blackland Clay Soil — Fort Worth's #1 Concrete Risk
Fort Worth's Blackland Prairie Vertisol clay has a Plasticity Index (PI) of 30–60+ — some of the highest shrink-swell potential in the US. During dry summers, these soils can shrink up to 4–6 inches at the surface, creating voids beneath unsupported slabs that collapse under load. Always pre-wet the subgrade to near-optimum moisture before pouring, install a minimum 4-in. compacted flex base, and use rebar or fiber mesh reinforcement on all slabs. Post-tensioned slab systems, now standard for new Fort Worth residential construction, significantly outperform conventionally reinforced slabs on Blackland clay.
How to Calculate Concrete for Fort Worth Projects
Measure length and width in feet and depth in inches. Multiply length × width × (depth ÷ 12) for cubic feet, then divide by 27 for cubic yards. Add at least 10% overage — Fort Worth suppliers including CEMEX, Martin Marietta (TXI), and Argos charge short-load fees of $100–$175 for orders under 3–5 cubic yards. For large commercial or foundation pours, get quotes from multiple Tarrant County suppliers — pricing competition in the active DFW market can save $10–$20 per yard on high-volume orders.
Example: 20 ft × 20 ft × 4 in = 133.3 cu ft ÷ 27 = 4.94 cu yd → Order 5.5 cu yd (w/ 10%)
⚠️ Fort Worth Blackland Clay & Extreme Heat Warning
Never pour concrete directly on dry, cracked Blackland clay — pre-wet the subgrade to within 2% of optimum moisture content and allow it to stabilize for 24–48 hours before pouring. In summer, never pour concrete when ambient temperature exceeds 90°F without ACI 305 hot-weather precautions. Fort Worth also experiences severe winter freezes — during rare but dangerous events like Winter Storm Uri (February 2021), temperatures dropped to 0°F. Never pour concrete when temperatures are forecast to drop below 40°F within 7 days without cold-weather protection per ACI 306.
Fort Worth Concrete Pricing — Current Reference
Fort Worth and Tarrant County sit in one of the most active and competitive ready-mix markets in the South Central US. The DFW Metroplex is served by major national producers including CEMEX, Martin Marietta (formerly TXI), Argos USA, Vulcan Materials, and several regional independents. Fort Worth pricing is generally slightly below DFW average due to the city's central location and good access to North Texas limestone aggregate. Pricing has risen moderately following post-pandemic construction demand and diesel cost increases, but remains well below coastal US markets.

Projects in unincorporated Tarrant County fall under county jurisdiction — confirm with Tarrant County for rural properties. Working without a permit risks Stop Work Orders and fines.
Fort Worth Concrete Project Tips
Pre-wet Blackland clay subgrade before every pour — Fort Worth's Vertisol clay soils are the #1 cause of premature concrete cracking in North Texas. In dry conditions, these soils shrink dramatically and create invisible voids below your slab. Always pre-wet the compacted subgrade to near-optimum moisture content (typically 20–25% by weight for Blackland clay) and allow it to stabilize 24–48 hours before pouring. Install a minimum 4-in. compacted crushed limestone or flex base over the prepared subgrade on all driveways, patios, and flatwork.
Always use rebar or fiber mesh on Fort Worth slabs — Unlike some southern markets where plain concrete is used for flatwork, Fort Worth's expansive Blackland clay makes reinforcement essential on virtually every slab. Use #3 or #4 rebar at 18 in. on center each way (on chairs, not laid on the ground), or specify fiber mesh admixture in the mix design. Unreinforced concrete slabs on Fort Worth clay have a documented service life of as little as 5–8 years before cracking becomes severe.
Schedule summer pours before 8 AM — Fort Worth averages 17+ days over 100°F annually. ACI 305 hot-weather provisions apply whenever air temperature exceeds 90°F. Schedule delivery before 8 AM during June–September, request a Type B retarder, and have your finishing crew fully staged before the truck arrives. Pre-cool mixing water or use ice in the mix design for large pours. Begin curing immediately with wet burlap or curing compound — Fort Worth's dry westerly winds can strip surface moisture from fresh concrete within minutes on hot, windy summer days.
Use proper control joint spacing for Texas thermal conditions — Fort Worth's temperature swing from winter lows near 20°F (during rare freeze events) to summer highs of 110°F means your concrete must accommodate extreme thermal expansion and contraction. Saw-cut or tooled control joints at intervals of 2.5× the slab thickness in feet (every 10 ft for a 4-in. slab) within 12–24 hours of placement. Inadequate control joint spacing causes uncontrolled random cracking on Texas flatwork, especially during the dramatic temperature swings of spring and fall.
Consider post-tensioned slab for any new construction on clay — Post-tensioned concrete slabs are the standard foundation system for new residential and commercial construction throughout Fort Worth and the DFW Metroplex. PT slabs use high-strength steel cables tensioned after the concrete cures to create a rigid, crack-resistant slab that performs dramatically better than conventional rebar slabs on Blackland clay. If building new construction, request quotes for PT slab design from a licensed Texas structural engineer — the modest cost premium typically pays for itself within 5–10 years in avoided repair costs.
Verify your contractor's TDLR license before hiring — Texas requires concrete and construction contractors to hold appropriate licensing through the Texas Department of Licensing and Regulation (TDLR). For larger projects, verify your general contractor's credentials at tdlr.texas.gov. Additionally, the Texas State License Board for Contractors regulates residential construction — always confirm licensing, insurance, and bonding before signing any concrete contract in Fort Worth.
Frequently Asked Questions — Fort Worth Concrete Calculator
How much does concrete cost per yard in Fort Worth, Texas?+
$130–$155 per cubic yard for standard 3,000 PSI ready-mix in Fort Worth/Tarrant County — slightly below the national average of $143–$158/yd. Higher-strength 4,000 PSI structural mix runs $148–$175/yd, and decorative stamped/colored runs $175–$245/yd. Short-load fees of $100–$175 apply for orders under 3–5 cubic yards. Fort Worth's competitive DFW Metroplex market and proximity to North Texas limestone aggregate keeps pricing attractive compared to coastal US markets.
What causes concrete to crack so much in Fort Worth?+
The primary cause is Fort Worth's Blackland Prairie Vertisol clay soils — extremely expansive clays with Plasticity Index values of 30–60+. These soils swell when wet and shrink dramatically during dry summers, creating voids beneath slabs that collapse under load and cause cracking. Secondary causes include: inadequate sub-base preparation, missing or improperly spaced control joints, summer heat causing rapid moisture loss during finishing, and insufficient reinforcement. Using a compacted flex base, proper rebar, pre-wetting the subgrade, and cutting control joints at correct intervals dramatically extends Fort Worth concrete service life.
What PSI concrete is required for Fort Worth driveways?+
3,000 PSI minimum for Fort Worth residential driveways per the Texas Building Code. Air entrainment is not required in Fort Worth's typically mild climate, though 3,500 PSI is recommended for driveways subject to heavy vehicles or occasional deicer use during rare winter freezes. Thickness should be 4–5 inches minimum over a 4-inch compacted flex base. Always use rebar or fiber mesh reinforcement on Fort Worth driveways — the Blackland clay soil makes reinforcement essential regardless of the neighborhood or lot conditions.
How many cubic yards for a typical Fort Worth driveway?+
A standard 20×20 ft Fort Worth driveway at 4 inches thick requires approximately 4.9 cubic yards (+ 10% waste = ~5.4 cu yd). At local pricing ($130–$155/yd), material cost runs approximately $702–$837. Full installed cost in Fort Worth including labor, flex base prep, rebar, forming, and finishing typically runs $3,500–$7,000 — lower than national average, reflecting Texas's competitive contractor labor market.
Do I need a permit for concrete work in Fort Worth?+
Yes, for most projects. Fort Worth Development Services requires permits for driveways, patio slabs, foundations, pool decks, and retaining walls over 4 ft. Apply online through Fort Worth Development Services. Standard residential flatwork permits process in 3–7 business days. Unpermitted work in Fort Worth can result in Stop Work Orders, required removal of the completed work, and fines — and creates disclosure problems when selling your home.
Should I use post-tensioned concrete for my Fort Worth foundation?+
Yes — strongly recommended. Post-tensioned (PT) slab-on-grade is the standard foundation system for new residential construction throughout Fort Worth and the entire DFW Metroplex, specifically because of the Blackland clay soil conditions. PT slabs create a rigid monolithic concrete slab that resists the differential movement caused by clay shrinkage and swelling far better than conventional rebar slabs. All major DFW homebuilders use PT foundations as standard practice. For existing slab repair or small additions, consult a licensed Texas structural engineer for specific reinforcement recommendations based on your parcel's soil conditions.
Who supplies ready-mix concrete in Fort Worth?+
Major ready-mix suppliers serving Fort Worth and Tarrant County include CEMEX (multiple DFW-area plants), Martin Marietta (formerly Texas Industries/TXI — the dominant North Texas producer), Argos USA, Vulcan Materials, and several strong regional independents. Martin Marietta controls significant North Texas limestone aggregate production, giving them a competitive advantage in ready-mix pricing across the Tarrant and surrounding counties. Always confirm delivery zones, minimum order quantities, short-load fees ($100–$175), and fuel surcharges when getting quotes for residential projects.
