What happens here
A worker is observed meticulously compacting the newly added crushed stone backfill behind the outcropping blocks using a jumping jack compactor. This step is vital for removing any air voids within the aggregate, increasing its density, and thereby enhancing the overall stability and performance of the retaining wall. The geotextile fabric that was brought up behind the blocks is then folded over the top of the compacted crushed stone layer. This final wrap completely encloses the drainage material, effectively preventing any topsoil or fine particles from migrating into the clean crushed stone, ensuring the drainage system remains clear and functional over time.
Goal: Ensure the ultimate stability and long-term drainage functionality of the retaining wall.
Tools and materials
- Compactor — Compacting the crushed stone backfill to achieve maximum density and stability
- Crushed Stone — The backfill material being compacted
- Geotextile Fabric — Wrapping over the top of the backfill to prevent soil migration and protect the drainage layer
- Outcropping Retaining Wall Blocks — The retaining wall structure being completed
