Continued Wall Building and Extended Backfill Preparation

anatomy of a well-structured soil-retaining wall
What happens here
The construction of the retaining wall continues upwards, repeating the sequence of laying natural stones, placing geotextile fabric, and backfilling with compacted drainage gravel. The video shows the wall nearing its final height, with multiple layers of gravel and fabric already incorporated. The geotextile fabric is left exposed at the top, ready to be folded over the uppermost layer of drainage gravel, creating a protective cap. The extensive excavated area behind the wall is crucial, as the narrator indicates it will be filled with additional backfill to secure the structure.
Goal: Complete the main physical structure of the retaining wall and prepare for final integration with surrounding soil.
Tools and materials
- Large Natural Stones — Continuing the courses of the retaining wall
- Level — Ensuring stones are laid level and plumb
- Mini Excavator Kubota — Lifting and placing heavy stones, and moving earth and gravel
- Plate Compactor — Compacting successive layers of gravel backfill
- Drainage Gravel — Continued backfill to provide drainage and support
- Geotextile Fabric — Soil stabilization and separation of layers
