What happens here
After the initial excavation, focus on constructing the foundational elements for the multi-level design. This includes building any necessary retaining walls and steps that define the different patio tiers. Level and compact a gravel base specifically for these structural elements. Then, lay the first course of retaining wall blocks or step risers, ensuring they are perfectly level both horizontally and front-to-back, and properly aligned. Use appropriate concrete adhesive or pins, as recommended by the block manufacturer, for stability. The video shows segments where retaining wall blocks are being set in place, defining the lower levels of the patio.
Goal: Build the structural retaining walls and steps for the multi-level patio.
Tools and materials
- Concrete Adhesive / Pins — Securing retaining wall blocks together, depending on the block system
- Level — Ensuring blocks are perfectly level
- Retaining Wall Blocks / Step Risers — Building the multi-level structures
- Rubber Mallet — Adjusting block placement without damage
- Shovel — Spreading gravel for wall/step bases
- String Line — Maintaining straight lines and alignment of blocks
- Tamper / Plate Compactor — Compacting the gravel base for retaining walls and steps
- Gravel N/A — Creating a stable base for retaining walls and steps
