What happens here
Line the excavated trench with heavy-duty geotextile fabric, ensuring there is enough fabric to extend vertically behind the entire height of the wall, with extra to fold over the top. This fabric acts as a barrier, preventing native soil from mixing with the drainage gravel and maintaining the gravel's effectiveness. Next, lay down a substantial layer of crushed gravel or road base (typically 3/4 inch clean stone) as the foundation for the first course of stones. Spread the gravel evenly across the bottom of the trench, ensuring it is level and at the correct height for the wall's base.
Goal: Create a stable, well-draining base for the retaining wall.
