So exciting to watch this go up
What happens here
Once the site is properly assessed and planned, begin spreading the chosen sub-base material, which is typically 4 to 6 inches of gravel or crushed stone (like the aggregate seen in the video). This material is essential for providing a stable, load-bearing foundation for the concrete slab and for facilitating drainage. Use a wheelbarrow to transport the material and a shovel and heavy-duty rake to distribute it evenly across the entire slab area. Spread the material to a preliminary depth, ensuring there's enough volume for subsequent layers and precise grading.
Goal: Distribute the primary layer of gravel or crushed stone.
Tools and materials
- Rake — Rough leveling and spreading of the initial gravel layer
- Safety Gloves — Protecting hands from sharp aggregate and preventing blisters
- Shovel — Loading material into the wheelbarrow and spreading gravel across the area
- Wheelbarrow — Transporting the sub-base material from delivery point to the slab area
- Crushed Stone/Gravel — Serving as the primary sub-base material for stability and drainage
