What happens here
Before laying any blocks, ensure the ground where the accent wall will stand is properly excavated, leveled, and compacted. A stable base of crushed gravel or road base is typically laid, compacted, and then topped with a leveling sand layer. The first course of interlocking concrete wall blocks is then carefully placed on this level foundation, ensuring it is perfectly straight and level in all directions. This initial course is critical as it sets the alignment for the entire wall. Although not explicitly shown, the video implies this foundational work has been completed as subsequent courses are being laid.
Goal: Establish a stable and level base for the wall
Tools and materials
- Interlocking Concrete Wall Blocks — The building material for the wall's structure
- Level — Checking the level of the foundation and first course
- Measuring Tape — Measuring dimensions and ensuring consistent block placement
- Shovel — Excavating the trench for the wall foundation
- String Line and Line Level — Establishing straight lines and level for the block courses
- Tamper — Compacting the gravel and sand base
- Crushed Gravel — Creating a stable, well-draining base for the wall
- Leveling Sand — Providing a fine-tuned level surface for the first course of blocks
