A retaining wall is a structure built to hold back soil (or other materials like rock or gravel) and resist the lateral pressure of the earth behind it.
Main purposes
- Stabilize slopes and prevent erosion — Stops soil from sliding or washing away on hillsides, embankments, or uneven ground.
- Create level, usable space — Turns a sloping yard into flat areas for patios, lawns, gardens, driveways, or outdoor living spaces (often by building terraces or steps).
- Manage water and drainage — Helps control runoff, reduce flooding risk, and protect foundations or lower areas from soil movement.
- Support structures or landscapes — Provides structural backing for roads, buildings, landscaping features, or to protect against landslides in hilly regions.
- Aesthetic and functional landscaping — Adds visual definition, seating, raised planters, or decorative elements while serving a practical role.
