What happens here
Establish the retaining wall by carefully laying the first courses of blocks on a prepared gravel base, ensuring proper alignment and stability. Utilize specialized blocks, including 'split half blocks' for corner detailing, which provide a rough, aesthetically pleasing face. Employ a gas-powered concrete saw (Husqvarna K770) to precisely cut blocks for drain tile placement, creating custom slots that secure the drain tile within the wall structure. Implement geo-grid reinforcement behind the wall, layering it with gravel and compacted soil. The importance of compacting each layer of backfill with a plate compactor (Tomahawk or Wacker) is emphasized to prevent future settling, which can compromise the wall's integrity. Throughout this process, the excavator (Daewoo) and skid steer (Volvo) continue to manage and deliver materials efficiently.
Goal: This step details the construction of the retaining wall's foundational layers, involving the precise placement of blocks and strategic backfilling with granular material and soil.
