Apply the Gravel Layer
Spread a layer of crushed rock about 3/4 inch thick throughout the excavation until level. Use a compaction plate to pack down the rock till the pieces mesh together, creating a strong foundation for the pavers. Check the gravel layer for level, shifting and compacting material as needed. Always wear ear protection and use caution when working with a compaction plate. If you're not confident of your ability to control this powerful tool, work with a helper or call in a pro.
