What happens here
With the geotextile fabric properly installed, the next critical phase is to install the base stone layer. This typically consists of crushed aggregate (like 3/4-inch minus with fines, or Class II Road Base), which provides the primary structural support and drainage for the paver patio. The presenter explicitly instructs to apply the base stone in thin layers, specifically "3 inches at a time." After each 3-inch layer is spread evenly across the entire surface, it must be thoroughly compacted using the same heavy-duty vibratory plate compactor used for the subsoil. This spreading and compacting process is repeated sequentially for each subsequent 3-inch lift until the desired total depth of the base stone is achieved. A typical paver patio requires 4-8 inches of compacted base stone, meaning this step will involve multiple cycles of spreading, leveling, and compacting.
Goal: Build a strong, stable, and well-drained load-bearing base for the pavers.
Tools and materials
- Level — Checking the grade, slope, and overall evenness of the base stone layers
- Rake — Spreading, leveling, and fine-grading the base stone layers
- Screed Boards — To guide the precise leveling of each base stone layer and establish the correct slope
- Shovel — Spreading the base stone evenly across the patio area
- Vibratory Plate Compactor Various — Compacting each 3-inch layer of base stone to maximum density
- Water Hose — Lightly moistening base stone before compaction to improve density
- Base Stone — Creating the load-bearing structural layer and drainage layer for the patio
