Preparing the Base with Geotextile and Crushed Stone

What happens here
Geotextile fabric, also referred to as landscape fabric or filter fabric, is carefully unrolled and laid along the bottom and up the sides of the excavated trench. This fabric serves as a critical barrier, preventing the backfill material from mixing with the native soil while still allowing water to permeate and drain. A substantial layer of crushed stone (gravel) is then deposited over the fabric at the base of the trench. This layer provides a stable, permeable, and level foundation upon which the first course of retaining wall blocks will be placed. A worker uses a jumping jack compactor to thoroughly compact this crushed stone base, ensuring maximum density and a solid footing for the wall.
Goal: Create a stable, permeable and level foundation for the retaining wall blocks.
Tools and materials
- Compactor — Compacting the base material to achieve maximum density and stability
- Crushed Stone — Creating a stable, well-draining base for the wall
- Geotextile Fabric — Separating backfill from native soil, allowing water drainage
- Level — Checking the levelness of the base layer
- Shovel — Spreading and leveling the crushed stone
