What's the difference between hydro excavation and air excavation?
Hydro excavation uses pressurized water to loosen soil and is usually faster in hard or compacted ground, but it creates slurry that needs disposal. Air excavation uses compressed air, leaves dry spoil that can often be reused as backfill, and works well in lighter soils. A provider recommends a method based on soil and site needs.
Key facts
- Hard soils / caliche: Can be slower
- Spoil: Dry, often reusable
- Water needs: No

|---|---|---|
| Hard soils / caliche | Generally faster | Can be slower |
| Spoil | Wet slurry, needs disposal | Dry, often reusable |
| Water needs | Yes | No |

Backfill considerations
Dry spoil from air excavation may be reused, which can reduce imported fill. Slurry from hydrovac generally can't be reused directly.
Availability
Hydrovac trucks are common in the Permian Basin. Ask providers which methods they offer.
