anatomy of a well-structured soil-retaining wall
What happens here
After placing a section of the wall stones, geotextile fabric is unrolled and laid along the excavated bank behind the wall, preventing soil erosion and separation. A layer of drainage gravel is then carefully poured behind the newly placed wall stones, on top of the geotextile fabric. A plate compactor is then used to thoroughly compact this layer of gravel, which is crucial for ensuring proper drainage, preventing settling, and providing structural stability to the wall. This process is repeated for each successive layer of wall stones.
Goal: Provide stable drainage and structural support behind the retaining wall.
