Perform Stone Backfill and Compaction

What happens here
Begin by ensuring the geotextile fabric is properly installed along the excavated trench, acting as a barrier between the native soil and the backfill material. Using a mini excavator, carefully deposit layers of stone backfill, such as crushed gravel or clean stone, into the trench behind the stone retaining wall. Each layer should be approximately 6 to 8 inches deep. After placing a layer of stone, use a plate compactor to thoroughly compact the material. Make multiple passes with the compactor to achieve maximum density. This process of layering and compacting should be repeated until the desired backfill height is reached, ensuring continuous stability for the retaining wall.
Goal: Achieve a dense and stable stone backfill behind the retaining wall.
