How to Build a Retaining Wall and 6 Reasons they Fail
What happens here
It is critical to ensure that water is directed away from the retaining wall, especially at vulnerable points. Failing to do so can lead to catastrophic wall failure due to saturated soil behind the wall. Two solutions are presented: either raising the height of the retaining wall in specific areas to redirect water from adjacent properties or creating a berm (an elevated ridge of earth) above the wall to prevent water from funneling into concentrated locations. Ignoring these measures can lead to soil erosion behind the wall, creating sinkholes and bowing out the wall.
Goal: Prevent water accumulation and soil erosion behind the retaining wall
