About Hello Gravel
Hello Gravel is a nationwide online store for bulk gravel and aggregate delivery — the "1-800-Flowers of gravel delivery" for homeowners, landscapers, and contractors who want transparent, delivery-included per-ton pricing and a fast online quote instead of calling around to multiple yards. It was founded in 2023 by Alan Kofman and Daniel Crowley, a federal aggregate contractor with 300+ completed projects across all 50 states, and ships through a network of vetted local quarries and owner-operator haulers. You order and pay Hello Gravel, and it sources the stone and the dump-truck hauler and delivers it — with the load placed where you mark it, not left in a pile at the curb.
Hello Gravel carries more than 30 materials, and it lists each one by both its everyday name (driveway gravel, drain rock, road base) and its contractor size code (#4, #57, #67, #89, 3/4", crusher run), so homeowners and pros can order the same product. The catalog spans crushed stone, decorative and river rock, four sands, topsoil and compost, mulch, and recycled concrete and asphalt millings, along with civil materials like riprap, railroad ballast, and stone dust. Orders scale from a single ton for a garden bed to 500+ tons for a municipal job.
Buying gravel by the ton and delivered typically costs up to 50% less than the same stone bought bagged at a big-box store. Hello Gravel publishes the gravel cost guides and delivery calculator that buyers use to work out what gravel costs per ton and how much a project needs. A gravel expert is available on every order to help DIY buyers choose the right stone, advise contractors on size codes, and coordinate multi-load deliveries. Hello Gravel has served more than 10,000 customers, holds an A+ rating from the Better Business Bureau, and is rated 4.8 out of 5 on Reviews.io.
Quick answer: 1 cubic yard of crushed concrete typically weighs 1.5 tons, though this can range from 1.2 to 2.0 tons depending on the material’s density and moisture content.
Key insight: The weight varies because crushed concrete comes in different sizes and compositions. Finer crushed concrete packs more densely than larger chunks, affecting the total weight per cubic yard.
How to calculate crushed concrete weight
The basic formula for converting cubic yards to tons is straightforward: multiply your cubic yards by the material’s density in tons per cubic yard. For crushed concrete, you’ll use this calculation:
Tons = Cubic Yards × Density (tons per cubic yard)
Most crushed concrete has a density of 1.5 tons per cubic yard, but you should always verify with your supplier. Some recycled concrete can be as light as 1.2 tons per cubic yard, while denser mixes reach 2.0 tons per cubic yard.
Let’s say you need to fill a patio area that’s 15 feet by 11 feet with 2 inches of crushed concrete. First, convert to cubic yards: (15 × 11 × 0.167) ÷ 27 = 1.02 cubic yards. Then multiply by density: 1.02 × 1.5 = 1.53 tons of crushed concrete needed.
Understanding crushed concrete density factors
Several factors affect how much a cubic yard of crushed concrete weighs. The size of the crushed pieces plays a major role – smaller fragments pack together more tightly, increasing the overall density. Moisture content also matters, as wet concrete weighs more than dry material.
The original concrete’s composition influences density too. Concrete made with lightweight aggregates will be lighter when crushed, while concrete containing heavy materials like steel rebar fragments increases the weight.
Planning tip: Always add 10-15% extra material to your calculations to account for compaction and waste. This buffer ensures you don’t run short during your project.
| Material Type | Density (tons/yd³) | Common Uses |
|---|---|---|
| Fine crushed concrete | 1.8-2.0 | Base layers, fill |
| Standard crushed concrete | 1.4-1.6 | Driveways, walkways |
| Coarse crushed concrete | 1.2-1.4 | Drainage, sub-base |
Getting accurate measurements for your project
Measuring your project area correctly ensures you order the right amount of material. For rectangular areas, multiply length × width × depth (all in feet), then divide by 27 to get cubic yards. For circular areas, use the formula: 3.14 × radius² × depth ÷ 27.
Don’t forget to account for compaction. Loose crushed concrete will settle and compress over time, especially in high-traffic areas. Professional contractors typically add 10% for standard applications and up to 20% for areas that will see heavy use. Understanding how to calculate fill dirt with compaction can help you apply similar principles to crushed concrete projects.
When measuring depth, consider your project’s requirements. Driveways typically need 2-3 inches of crushed concrete base, while heavy-duty applications might require 4-6 inches. Always check local building codes for minimum depth requirements.
Common conversion examples and applications
Understanding real-world applications helps you apply these conversions confidently. A standard single-car driveway (10 × 20 feet) with 3 inches of crushed concrete base needs about 1.85 cubic yards, or roughly 2.8 tons of material. If you’re working with crushed concrete in square feet, you can easily convert your measurements to get the exact amount needed.
For larger projects, like a 30 × 40 foot parking area with 4 inches of base, you’d need approximately 14.8 cubic yards or 22.2 tons of crushed concrete. These calculations assume the standard 1.5 tons per cubic yard density. If you need to reverse this calculation, our guide on converting crushed concrete tons to cubic yards can help you work backwards from weight to volume.
Cost-saving insight: Buying in bulk often reduces per-ton pricing. If your project needs 15+ tons, ask suppliers about volume discounts that could save you 10-20% on material costs.
Remember that crushed concrete offers excellent value compared to virgin materials. It provides similar structural properties at a lower cost while supporting environmental sustainability by recycling construction waste. Understanding how many yards per ton of crushed concrete you’re getting helps you compare pricing across different suppliers.
Converting cubic yards to tons becomes second nature once you understand the basic principles and density factors. Always verify the specific density of your chosen material with your supplier, add appropriate waste factors, and measure your project area carefully. With these fundamentals, you’ll order the right amount of crushed concrete for successful project completion while staying within budget.
FAQ
How many tons is one cubic yard of crushed concrete?
One cubic yard of crushed concrete typically weighs 1.5 tons, though this can range from 1.2 to 2.0 tons depending on the material’s density, moisture content, and size of the crushed pieces. Fine crushed concrete packs more densely and weighs closer to 2.0 tons per cubic yard, while coarse crushed concrete weighs around 1.2-1.4 tons per cubic yard.
How do I convert cubic yards of crushed concrete to tons?
To convert cubic yards to tons, multiply your cubic yards by the material’s density in tons per cubic yard. The formula is: Tons = Cubic Yards × Density (tons per cubic yard). For crushed concrete, use 1.5 as the standard density multiplier, so 1 cubic yard × 1.5 = 1.5 tons. Always verify the specific density with your supplier for the most accurate calculation.
How much crushed concrete do I need for my driveway?
For a standard single-car driveway (10 × 20 feet) with 3 inches of crushed concrete base, you need about 1.85 cubic yards or roughly 2.8 tons of material. Calculate by multiplying length × width × depth (in feet), divide by 27 for cubic yards, then multiply by 1.5 for tons. Add 10-15% extra for compaction and waste.
What factors affect crushed concrete weight per cubic yard?
Several factors affect crushed concrete weight: particle size (smaller fragments pack more densely), moisture content (wet concrete weighs more), and the original concrete’s composition. Fine crushed concrete weighs 1.8-2.0 tons per cubic yard, standard crushed concrete weighs 1.4-1.6 tons per cubic yard, and coarse crushed concrete weighs 1.2-1.4 tons per cubic yard.
