Garage Slab Excavation — 24 × 24 × 1 ft
A shallow 24 × 24 ft garage slab excavation 1 foot deep removes about 21 cubic yards of material.
How to use this tool
- Enter excavation length, width, and depth in feet.
- The calculator returns volume in cubic feet, cubic yards, and estimated truck loads.
- Account for soil swell (excavated soil expands by 20–30% in volume).
Find how many cubic yards of soil are displaced for a standard two-car garage concrete slab.
Frequently asked questions
- How do I calculate excavation volume?
- Multiply length × width × depth in feet to get cubic feet. Divide by 27 to convert to cubic yards. A standard dump truck holds about 10–14 cubic yards.
- How many cubic yards fit in a dump truck?
- A standard single-axle dump truck holds about 10 cubic yards. Tandem and tri-axle trucks can carry 14–20 cubic yards.
