What happens here
To manage water runoff effectively and protect the house foundation, lay down non-permeable black poly plastic sheeting over the prepared ground. Ensure the sheeting overlaps sufficiently to prevent water penetration and extends to direct water away from the building. Alongside the retaining wall, permeable heavy-duty boulder fabric is already installed, allowing water to drain through while holding soil in place. This two-layer approach ensures both drainage and structural integrity.
Goal: Create a robust drainage system to protect the foundation.
