Base
Budget compactable base for drives, pads and access roads.
A crushed blend of shell and limerock, lighter in colour than straight limerock and usually a little cheaper. It compacts well and is a long-standing Florida base material, especially on the coast.
It does not bind quite as hard as limerock base and the surface stays a touch looser, so it is the budget choice rather than the spec choice. For a residential driveway or a ranch road, the difference rarely matters.

How much to order
One cubic yard is 27 cubic feet. How far that goes depends entirely on how deep you are laying it.
| Depth | 1 cu yd covers | Yards per 500 sq ft |
|---|---|---|
| 2 in | 162 sq ft | 3.1 cu yd |
| 3 in | 108 sq ft | 4.6 cu yd |
| 4 in | 81 sq ft | 6.2 cu yd |
| 6 in | 54 sq ft | 9.3 cu yd |
| 12 in | 27 sq ft | 18.6 cu yd |
The arithmetic: length times width times depth, all in feet, divided by 27. A 40 by 20 ft area at 4 inches deep is 40 × 20 × 0.333 ÷ 27, which is about 9.9 cubic yards, so you order 10. Round up rather than down — coming up two yards short on a Friday costs a whole extra delivery.

Multiply length by width by depth, all in feet, and divide by 27 to get cubic yards. One cubic yard covers 162 sq ft at 2 inches, 108 sq ft at 3 inches, 81 sq ft at 4 inches or 54 sq ft at 6 inches. The calculator does it for you and converts to tons and truckloads.
Yes. Shell Rock is compacted in lifts, so it loses roughly a fifth of its loose volume once it is watered and rolled. Order 20 percent above your plan volume. Our calculator adds that automatically.
$27.50 per cubic yard, plus a flat $200 delivery per order across Palm Beach, Broward and Miami-Dade. Minimum order is one cubic yard.
About 1.50 tons per cubic yard. A tri-axle carries roughly 18 cubic yards or 22 tons, whichever it reaches first, so a full load of Shell Rock is about 14.7 cubic yards.
