Use this Concrete Calculator in Shreveport, LA to estimate concrete for slabs, patios, driveways, sidewalks, parking pads, footings, piers and posts. Calculate cubic yards, cubic feet and cubic meters, add a project allowance, compare bag quantities and enter your own Shreveport ready-mix price for a simple material-cost estimate.
Estimate slabs and driveways, continuous footings, round piers/posts, or convert a known concrete volume into bags and cost.
Estimate patios, driveway slabs, parking pads, sidewalks and other rectangular flatwork.
Quantity estimate only. Thickness, reinforcement, joints, subbase, drainage and permit requirements must follow the actual Shreveport project.
Estimate continuous footing, grade-beam or trench-fill volume from total length, width and depth.
Use approved/project footing dimensions. Soil movement, loads, reinforcement and structural design are separate issues.
Calculate concrete for straight cylindrical piers, drilled holes and round post footings.
Straight-cylinder estimate only. Required pier/post diameter, depth, bearing and uplift resistance must be determined separately.
Convert a known volume into cubic yards, cubic feet, cubic meters, bag quantities and optional material cost.
Verify actual bag yield and obtain a current supplier quote. Delivery, short-load, pump, access and waiting charges are separate unless included.
A Concrete Calculator in Shreveport helps homeowners, contractors and estimators calculate material for patios, driveways, parking slabs, sidewalks, garage floors, footings, piers and post foundations. Shreveport sits in the Shreveport-Bossier region, where long hot summers, thunderstorms and occasional winter freezes can affect placement even though the geometric volume remains the same.
The calculator separates quantity from structural design. Enter the dimensions that apply to the actual project and use a current supplier quote for cost planning. Do not rely on a city-page calculator to choose slab thickness, foundation size, reinforcement or soil design.
Estimate patios, driveways, sidewalks and parking slabs from measured dimensions.
Calculate continuous footing and grade-beam quantity from approved dimensions.
Estimate cylindrical pier/post-hole concrete with optional post displacement.
Summer heat, thunderstorms and winter freezes can affect placement and curing plans.
For a rectangular slab, multiply length by width by thickness. Convert thickness from inches to feet before multiplying. The result is cubic feet. Divide cubic feet by 27 to get cubic yards.
Use actual dimensions from plans, forms or field measurements.
Divide slab thickness, footing width and footing depth by 12.
Use rectangular or cylindrical geometry.
Divide cubic feet by 27.
Use a field allowance appropriate to the actual conditions.
Length and width are in feet; thickness is entered in inches.
One cubic yard contains 27 cubic feet.
Assumes a constant rectangular cross-section.
Convert diameter and depth to feet before calculating.
Flatwork is one of the most common uses for a concrete calculator in Shreveport. Patios, garage floors, parking slabs, private walks and driveway sections can usually be divided into rectangles. If one area is thicker than another, calculate each zone separately.
A 200-square-foot slab at 4 inches thick contains about 2.47 cubic yards before allowance. At 6 inches thick, the same plan area contains about 3.70 cubic yards. Those numbers compare volume only; they are not thickness recommendations.
| Area | 4 in | 5 in | 6 in | Purpose |
|---|---|---|---|---|
| 100 ft² | 1.23 yd³ | 1.54 yd³ | 1.85 yd³ | Volume comparison |
| 200 ft² | 2.47 yd³ | 3.09 yd³ | 3.70 yd³ | Volume comparison |
| 400 ft² | 4.94 yd³ | 6.17 yd³ | 7.41 yd³ | Volume comparison |
| 600 ft² | 7.41 yd³ | 9.26 yd³ | 11.11 yd³ | Volume comparison |
Geometry examples only; not structural recommendations.
Driveways can widen near the garage, include parking bays or transition through a public approach before meeting the street. Divide irregular private paving into rectangles and add the volumes. Keep a driveway approach separate when it uses different dimensions or City requirements.
Shreveport's official building-permit FAQ states that if a new driveway is required, a permit must be obtained from the Office of the City Engineer. The Permits & Inspections Division can assist in determining whether a driveway permit is needed.
For a dedicated parking slab workflow, use the Concrete Parking Pad Calculator.
Shreveport Public Works maintains dedicated City streets, curb-and-gutter systems, public City building parking lots, sidewalks and roadside drainage. Its Streets & Drainage division also maintains roadside right-of-way ditches and driveway pipes within its jurisdiction.
This matters for concrete estimating because a private slab is not automatically the same as a public sidewalk, curb repair or street-connected driveway. When concrete affects City infrastructure, use the approved dimensions and coordinate with the appropriate City office before placement.
Shreveport's current Building Codes page states that construction must conform to the 2021 International Building Code, 2021 International Existing Building Code, 2021 International Residential Code, 2021 International Mechanical Code, 2021 International Plumbing Code, 2021 International Fuel Gas Code and the 2020 National Electrical Code, together with local ordinances and Louisiana state amendments.
Concrete work that is part of a building foundation, structural addition, retaining system or other regulated construction can involve plan review, inspections and code requirements far beyond cubic yards. Use the City code page and approved project documents for the permit date.
Footing quantity is calculated from total run length × width × concrete depth. Use approved project dimensions. Earth-formed trenches may consume more concrete if the excavation is oversized or soil sloughs into the trench.
Northwest Louisiana foundation work can involve expansive soils, building loads, reinforcement, drainage and movement considerations. This page does not size foundations or determine soil design. It converts known dimensions into cubic yards.
Round piers and post holes use cylindrical geometry. Enter diameter, depth and count. If a square or round embedded post occupies the full entered depth, the calculator can subtract a simplified displacement volume.
Fence posts, patio covers and structural piers do not share one universal size. Wind, uplift, bearing, loads and soil conditions matter. Use the project-required diameter and depth first, then calculate quantity.
For dedicated tools, use the Concrete Fence Post Calculator or Concrete Pier Size Calculator.
Shreveport has a humid subtropical climate with hot summers. National Weather Service Shreveport climate reports use the 1991–2020 normal period; a late-July normal daily maximum is about 95°F, illustrating the heat that can affect midsummer placement.
Heat does not change the geometric cubic yards, but high concrete temperature, sun and wind can increase slump loss and shorten finishing time. High humidity can reduce evaporation compared with very dry climates, yet hot exposed slabs can still require careful delivery, finishing and curing planning.
Coordinate delivery and finishing so fresh concrete is not delayed during high temperatures.
Warm-season humidity and thunderstorms can quickly change placement conditions.
Northwest Louisiana can still experience freezing weather, so cold-weather protection occasionally matters.
National Weather Service climate information for the Shreveport-Bossier area says normal annual rainfall is just over 51 inches, with monthly averages varying from under 3 inches in August to more than 5 inches in May and June.
Rain does not change the intended geometry, but runoff can soften subgrade, erode slab edges, widen footing trenches and affect post-hole dimensions. If significant rain occurs after excavation or grading, remeasure before finalizing the ready-mix order.
Shreveport Public Works also maintains roadside drainage ditches, underground drainage systems and driveway pipes within its jurisdiction, so public drainage work should be coordinated separately from this material-volume calculation.
Bagged concrete is practical for small post holes or repairs. The calculator uses approximate planning yields of 0.30 ft³ for a 40 lb bag, 0.45 ft³ for a 60 lb bag and 0.60 ft³ for an 80 lb bag. Verify the actual product label before purchase.
Several cubic yards usually favor ready-mix because hand mixing becomes labor intensive. Ask the supplier about minimum loads, short-load charges, truck access, pump needs, delivery windows and hot-weather scheduling.
A single “Shreveport concrete price per yard” can become outdated quickly. Mix design, strength, admixtures, order size, delivery, short-load fees, pumping, waiting time and site access can all change real cost.
The calculator leaves the price input blank so you can enter a current quote from the supplier or contractor serving the project.
Labor, formwork, reinforcement, excavation, permits, pumping, testing and tax are separate unless included in the quote.
Suppose a patio measures 20 feet by 12 feet and is 4 inches thick. The plan area is 240 square feet. Four inches equals one-third of a foot, producing about 80 cubic feet of exact concrete volume.
Divide 80 by 27 to get about 2.96 cubic yards. With a 10% allowance, planned quantity becomes about 3.26 cubic yards. Enter a current Shreveport supplier price to estimate the simple material value.
The example demonstrates geometry only; it does not determine whether 4 inches is the correct thickness.
Shreveport's location near the Red River and its network of urban drainage systems make site drainage an important planning issue on some properties. The concrete calculator should be used after finished elevations, slopes and drainage paths are established—not as a substitute for stormwater or floodplain design.
If a project is in a low area, near a drainage channel or tied to public storm infrastructure, verify the applicable City, parish and project requirements before changing grades or placing a large impervious slab. The volume formula tells you how much concrete fills the forms; it does not determine whether the finished site drains correctly.
Measure the actual section, convert inches to feet, calculate cubic feet and divide by 27.
Measure: use actual project dimensions.
Convert: inches ÷ 12 before multiplying by feet.
Calculate: use rectangular or cylindrical geometry.
Order: cubic feet ÷ 27, then add your allowance.
