How Much Recycled Concrete Aggregate for 100 Square Feet?
How much recycled concrete aggregate for 100 square feet depends on depth. At 4 inches you need about 1.23 cubic yards, roughly 1.6 tons at 1.3 tons per yard. Going to 6 inches raises it to 2.4 tons.
Volume and tonnage calculator →Recycled concrete aggregate for 100 sq ft by depth
| Depth | Cubic yards | Tons | Tons +10% |
|---|---|---|---|
| 3 in | 0.93 | 1.2 | 1.3 |
| 4 in | 1.23 | 1.6 | 1.8 |
| 6 in | 1.85 | 2.4 | 2.6 |
Working it out
- 100 sq ft × (4 ÷ 12) ft = 33.3 cubic feet.
- ÷ 27 = 1.23 cubic yards.
- × 1.3 tons per yard = 1.6 tons.
About recycled concrete aggregate
Ask whether the recycled concrete has been screened for rebar and debris. Fresh-crushed concrete can also be alkaline, so keep it away from sensitive plantings and streams. Typical weight: 1.2 to 1.4 tons per cubic yard.
Getting the order right
- Measure odd shapes in pieces. Split curves and L-shapes into rectangles and add them.
- Add a margin. About 10 percent covers compaction and low spots.
- Bulk or bags. Bulk delivery is the practical choice here.
- Prep first. Remove sod, compact the subgrade and set edging before the stone arrives.
Use the volume and tonnage calculator for any other size.
Where recycled concrete aggregate fits
Best suited to:
- Driveway and pad bases
- Temporary construction entrances
- Fill under slabs when compacted in lifts
Less suited to:
- Near ponds, streams or sensitive plants, since fresh crush can raise pH
- Decorative top layers
- Drainage layers, unless the product is clean and screened
Quick reference numbers
- Per inch over 100 sq ft: about 0.40 tons of recycled concrete aggregate (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.0 tons.
- Another size for comparison: a 12x24 area at 2 inches takes about 2.3 tons.
- Weight used here: about 1.3 tons per cubic yard.
Mistakes that throw off the order
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
