Estimate concrete for driveways, patios and garage floors.
Calculate repeated foundation pads and post-support concrete.
Estimate straight concrete walls, curbs and rectangular sections.
Convert volume into bags, trucks and editable current pricing.
A Concrete Calculator in Providence starts with finished concrete dimensions. Measure the actual slab, footing, wall or pad rather than the entire excavation, gravel base or work zone. Select the project type above and enter the dimensions.
The calculator converts cubic feet into cubic yards and applies an optional planning allowance. Small projects can be translated into bag quantities, while larger pours can be checked against truck capacity and current supplier pricing.
Use finished concrete dimensions.
Choose slab, footing, wall or delivery.
Get cubic feet and cubic yards.
Account for normal field variation.
Confirm supplier, permit and inspection requirements.
Rectangular slabs use length × width × thickness. If length and width are measured in feet and thickness is entered in inches, divide thickness by 12 before multiplication.
Use finished dimensions for patios, driveway sections, garage floors and other flatwork.
A 20-foot by 12-foot slab at 4 inches thick covers 240 square feet. Four inches equals approximately 0.333 foot.
The final ready-mix order may need to be rounded to the supplier's accepted increment.
Driveways and patios are often easy to estimate as rectangular sections. If a driveway widens, contains a parking pad or has changes in thickness, calculate each section separately so the total matches the actual concrete footprint.
| Project | Example Size | Thickness | Approx. Exact Volume |
|---|---|---|---|
| Small Patio | 10 × 12 ft | 4 in | 1.48 yd³ |
| Large Patio | 20 × 16 ft | 4 in | 3.95 yd³ |
| Driveway Section | 20 × 10 ft | 5 in | 3.09 yd³ |
| Garage Floor | 20 × 20 ft | 4 in | 4.94 yd³ |
Use the Concrete Slab Calculator for slab-specific estimating and the Rectangular Concrete Calculator for several straight-sided sections.
The Footing & Pad panel estimates square or rectangular footings under posts, columns and other supports. Enter the dimensions of one footing, then multiply by the number of identical footings.
Convert inch-based depth to feet before calculating cubic feet.
Use the Concrete Footing Calculator for dedicated footing geometry. Final footing dimensions and reinforcement should come from the project design.
Straight walls and curbs with constant cross-section can be estimated as rectangular prisms. Multiply total length by height and thickness. Where the dimensions change, calculate each portion separately.
Divide thickness in inches by 12 before multiplying.
Use the Concrete Wall Calculator for wall-specific volume planning.
Small repair areas and isolated pads may be manageable with bagged concrete. Multi-yard slabs can require many bags and mixer cycles, so ready-mix may be more practical for continuous placements.
| Bag Size | Approx. Yield Used | Bags per yd³ |
|---|---|---|
| 40 lb | 0.30 ft³ | About 90 |
| 60 lb | 0.45 ft³ | About 60 |
| 80 lb | 0.60 ft³ | About 45 |
Verify the actual bag yield on the selected product before purchasing.
Mixer-truck capacity varies by producer, vehicle and route. Enter the supplier's usable capacity rather than assuming every truck carries the same volume.
The last load may be partial and may have different pricing or minimum-load charges.
For short-load fees and truck spacing, use the Concrete Delivery Calculator.
Ready-mix concrete cost can change with mix, order size, delivery distance, fuel, minimum-load rules and supplier policies. The calculator therefore leaves the local price field editable rather than hard-coding a Providence price.
Add per-truck delivery fees when applicable. Pumping, labor, reinforcement, finishing and permits are separate.
Concrete work that is part of a building, addition, foundation, structural wall, major alteration or other regulated construction may require permits and inspections through the City of Providence Department of Inspections and Standards. Providence's own service information directs residents with permit questions about current or previous building work to Inspections & Standards, including work involving interior or exterior renovations and building-code or use changes.
Providence also uses the ViewPoint Cloud platform for online permitting. The City has described ViewPoint as the same online permitting platform used for building permits and other municipal applications, allowing applicants to submit information, make payments and follow approval steps electronically.
Permitted concrete work and material estimating should be treated as separate parts of the project. The City of Providence Department of Inspections and Standards performs field inspections and administers code-enforcement functions, while permit questions for current or prior building work are routed through that department.
For a regulated footing, foundation, structural slab or wall, verify the inspection sequence before the pour. Forms, reinforcement, excavation and other work may need to remain visible until the applicable inspection is completed. Use the Concrete Pouring Checklist to prepare materials and crew, but follow the permit documents and inspector instructions for timing.
Providence concrete projects can experience freezing winter temperatures, snow, rain, coastal wind, summer heat and repeated freeze-thaw cycles. These conditions do not change the geometric volume calculation, but they can affect placement timing, curing, surface protection and the concrete mixture specified for exterior work.
For winter placement planning, use the Concrete Cold Weather Calculator. For warmer conditions, use the Concrete Hot Weather Calculator where applicable. Mix selection, air entrainment, strength, curing and exposure requirements should follow project specifications and qualified concrete guidance.
Foundation work may contain strip footings, isolated pads, foundation walls, piers and slabs. Estimate each geometry separately instead of applying one average thickness to the entire foundation.
Related tools include the Concrete Foundation Calculator, Concrete Pier Calculator, Concrete Rebar Weight Calculator and Concrete Control Joint Calculator.
Providence projects may involve older neighborhoods, narrow streets, tight driveways, limited curb space, active traffic and restricted staging areas. Before ordering ready-mix, confirm where the mixer can safely stop, whether a pump or conveyor is needed and how quickly the crew can discharge each load.
Winter parking restrictions, snow events and street access can also affect delivery planning. For large pours, coordinate truck spacing so loads do not arrive faster than the crew can place and finish them. Use the Concrete Delivery Calculator for truck count and the Concrete Mixer Capacity Calculator for site-mixed batches.
Concrete projects that affect a public street, sidewalk, curb, utility area or other City-controlled space may involve the Department of Public Works in addition to building-permit review. Providence's current PVD311 information says Public Works Engineering, Highway, Sewer, Traffic and Parking services now operate from the Department's Chapman Street location, and permit applications or document drop-offs can be handled there when an in-person visit is needed.
Before ordering concrete for a driveway approach, sidewalk repair, curb, utility cut or other public-space work, verify which City department controls the work and whether a separate approval is needed. The concrete calculator estimates material only; it does not determine public-right-of-way authorization.
For concrete design, construction and ready-mix information, consult the American Concrete Institute (ACI) and National Ready Mixed Concrete Association (NRMCA). Final dimensions, thickness, concrete strength, reinforcement and structural details should follow approved project requirements.
Measure the project, calculate cubic yards, add a planning allowance and verify supplier and City requirements.
