Question: When using an excavator to spread topsoil over a newly graded area, what is the best practice to achieve a uniform thickness and minimize future settlement and uneven growth?
Answer options:
- Spread the topsoil in one thick layer and then compact it heavily. ✅ Place topsoil in consistent, thin lifts (e.g., 150-300 mm or 6-12 inches) and lightly blend.
- Pile the topsoil in mounds and let weather conditions naturally spread it.
- Push large quantities of topsoil as quickly as possible with the bucket on the ground.
Correct answer: Place topsoil in consistent, thin lifts (e.g., 150-300 mm or 6-12 inches) and lightly blend.
Explanation: Spreading topsoil in consistent, relatively thin lifts helps ensure even distribution, allows for proper compaction by equipment weight or light tamping, and promotes uniform future growth and drainage.
