New JerseyConcrete Calculator — Yards, Bags & Cost
Calculate cubic yards, bags needed, and NJ-accurate ready-mix costs for any New Jersey concrete project — driveways, sidewalks, patios, foundations, footings & more.
The New Jersey Concrete Calculator helps homeowners, contractors, and property owners estimate cubic yards, bag count, and ready-mix costs for any concrete project in New Jersey. NJ pricing typically runs $160–$225/yd — above the national average — due to high labor costs, dense suburban delivery conditions, and northern NJ freeze-thaw requirements.

New Jersey Concrete Calculator — What You Need to Know
New Jersey concrete projects span two climate zones: northern NJ (Bergen, Morris, Essex counties) experiences heavy freeze-thaw cycles requiring air-entrained mixes, while southern NJ (Cape May, Cumberland, Atlantic counties) is more temperate. The NJ Uniform Construction Code (UCC) governs all structural concrete work, adopting the International Building Code (IBC) with NJ amendments. Most residential concrete work requires a local municipal permit — check with your NJ Division of Codes & Standards or township office.
🔵 NJ UCC Minimum Concrete Requirements
Exterior flatwork (driveways, sidewalks): 3,500–4,000 PSI min · Structural exposed to weather: 4,000–4,500 PSI · Air entrainment: 4.5–7.5% for freeze-thaw zones (northern NJ) · W/C ratio: max 0.45 · Frost depth: 36 in. (north NJ), 24–30 in. (south NJ). Always confirm specs with your licensed NJ contractor or engineer.
🚗 NJ Driveway Concrete
A standard 10×20 ft NJ residential driveway at 6 inches needs ~3.7 cubic yards. NJ ready-mix cost: $680–$820. Municipal permits and driveway apron specs vary by township — always check local ordinances before pouring.
🏠 NJ Sidewalk & Walkway
NJ sidewalk slabs typically require 4 in. depth at 3,500–4,000 PSI with air entrainment in northern counties. A 20 ft × 4 ft walk uses ~1 cubic yard. Homeowners are responsible for sidewalk maintenance in most NJ municipalities.
🏗️ NJ Foundation & Basement
NJ basement floors and foundations require 4,000–4,500 PSI with waterproofing admixtures. Frost depth in northern NJ reaches 36 inches, so footings must be placed accordingly. NJ UCC structural permit is mandatory for all foundation work.
How to Calculate Concrete Volume in New Jersey
Break your project area into rectangles or cylinders (for columns and post holes). Measure in feet for length and width, and convert thickness from inches to feet before multiplying. Divide cubic feet by 27 to get cubic yards. Always add a 10% waste factor — NJ suppliers often have short-load minimums and re-orders can delay your pour by days.
Example: 20 ft × 10 ft NJ driveway × 6 in = 100 cu ft = 3.70 cu yd → Order 4.1 cu yd
⚠️ NJ Short-Load & Minimum Order Fees
Most NJ ready-mix suppliers charge a short-load fee of $100–$250 for orders under 4–6 cubic yards. For small jobs under 0.75 cu yd, bagged concrete (Quikrete or Sakrete) from Home Depot, Lowe's, or local building supply stores is more cost-effective. Break-even point is roughly a 10×10 ft, 4-inch slab.
New Jersey Concrete Pricing — Current Reference
NJ ready-mix pricing runs 15–40% above national averages due to high land costs for batching plants, elevated labor rates, and dense suburban delivery logistics. Northern NJ (near NYC metro) commands the highest prices, while southern NJ (near Philadelphia metro) is slightly more affordable.

New Jersey Concrete Cost by Region
NJ is split into distinct pricing regions driven by proximity to NYC, Philadelphia, and local batching plant density. Northern NJ generally commands a premium, while central and southern NJ offer more competitive rates. Use the table below as a regional starting point — always get 3 quotes from local suppliers.

NJ homeowners can verify licensed contractors through the NJ Division of Consumer Affairs at njconsumeraffairs.gov. Always request a copy of your contractor's NJ Home Improvement Contractor (HIC) registration and liability insurance certificate before any concrete work begins.
New Jersey Concrete Project Tips
Check municipal permits first — most NJ townships require permits for driveways, sidewalks, and any structural concrete work. Fines for unpermitted work vary widely by municipality.
Use air-entrained mix in northern NJ — Bergen, Morris, Passaic, and Essex counties see 30–50 freeze-thaw cycles per year. Non-entrained concrete will spall within 2–3 winters.
Set footings below frost line — 36 inches in northern NJ, 24–30 inches in central NJ. Shallow footings will heave and crack with ground frost movement.
Seal driveways after curing — NJ roads use heavy road salt (sodium chloride and calcium chloride). Seal concrete driveways with a penetrating sealer after 28-day cure to prevent salt damage.
Schedule pours in moderate temps — NJ summers can reach 95°F+, accelerating set time. Pour early morning and keep concrete moist for 7 days. Below 40°F, use heated enclosures per ACI 306.
Order 10% extra — NJ suppliers charge short-load fees for orders under 4–6 yards. It is cheaper to over-order slightly than to pay a second delivery charge.
Get 3 ready-mix quotes — NJ has dozens of regional suppliers (Eastern Concrete, Tilcon, Vulcan Materials, Irving Materials). Prices vary by $20–$40/yd between suppliers in the same county.
Frequently Asked Questions — New Jersey Concrete Calculator
How much does concrete cost per yard in New Jersey?+
$160–$230 per cubic yard for standard 3,500–4,000 PSI ready-mix in New Jersey, compared to the national average of $125–$165/yd. Northern NJ (Bergen, Morris, Hudson counties near NYC) commands the highest prices at $185–$230/yd. Short-load fees of $100–$250 typically apply for orders under 4–6 yards.
Do I need a permit for concrete work in New Jersey?+
Yes for most work. Under the NJ Uniform Construction Code (UCC), permits are required for foundations, structural slabs, retaining walls, and most driveways and sidewalks. Each NJ municipality enforces its own local ordinances — contact your township construction office or the NJ Division of Codes & Standards to confirm what requires a permit in your area.
What PSI concrete is required for NJ driveways?+
For NJ residential driveways exposed to weather and freeze-thaw cycles, 4,000 PSI with 4.5–7.5% air entrainment is the industry standard in northern NJ. Southern NJ can use 3,500 PSI where freeze-thaw is less severe. Most contractors default to 4,000 PSI statewide for durability. Minimum depth is 6 inches for vehicle traffic per ACI 330.
How deep must footings be in New Jersey?+
NJ frost depth varies by region: 36 inches in northern NJ (Bergen, Passaic, Morris, Sussex counties), 30 inches in central NJ (Monmouth, Somerset, Mercer), and 24 inches in southern NJ (Burlington, Camden, Atlantic). All footings for permanent structures must extend below the local frost line to prevent frost heave. Confirm exact depth requirements with your NJ municipal construction office.
Who supplies ready-mix concrete in New Jersey?+
Major NJ ready-mix suppliers include Eastern Concrete Materials (statewide), Tilcon New Jersey (northern/central NJ), Vulcan Materials (south/central NJ), Irving Materials, and numerous local independent yards. Many suppliers serve specific county zones, so local sourcing is often more affordable than large regional chains.
How many cubic yards for a standard NJ driveway?+
A typical NJ two-car driveway at 20 ft × 20 ft × 6 inches requires approximately 7.4 cubic yards (plus 10% waste = 8.2 cu yd). At current NJ pricing ($178–$215/yd for 4,000 PSI), material alone costs roughly $1,460–$1,760. Full installed cost including labor, gravel base, and forming typically runs $5,500–$11,000 in NJ.
How long does concrete take to cure in NJ?+
24 hrs foot traffic · 3 days form removal · 7 days light vehicles · 28 days full design strength. In NJ winters (below 40°F), insulating blankets and extended cure times are required per ACI 306. Keep concrete moist for at least the first 7 days and avoid de-icing salts for the first full winter season after placement.
